The MAX3372E–MAX3379E and MAX3390E–MAX3393E ±15kV ESD-protected level translators provide the level shifting necessary to allow data transfer in a multivoltage system. Externally applied voltages, VCCand VL, set the logic levels on either side of the device. A low-voltage logic signal present on the VLside of the device appears as a high-voltage logic signal on the VCCside of the device, and vice-versa. The MAX3374E/MAX3375E/MAX3376E/MAX3379E and MAX3390E–MAX3393E unidirectional level translators level shift data in one direction (VL→ VCCor VCC→ VL) on any single data line. The MAX3372E/MAX3373E and MAX3377E/MAX3378E bidirectional level translators utilize a transmission-gate-based design (Figure 2 in the full data sheet) to allow data translation in either direction (VL⇔ VCC) on any single data line. The MAX3372E–MAX3379E and MAX3390E–MAX3393E accept VLfrom +1.2V to +5.5V and VCCfrom +1.65V to +5.5V, making them ideal for data transfer between low-voltage ASICs/PLDs and higher voltage systems.All devices in the MAX3372E–MAX3379E, MAX3390E–MAX3393E family feature a three-state output mode that reduces supply current to less than 1µA, thermal shortcircuit protection, and ±15kV ESD protection on the VCCside for greater protection in applications that route signals externally. The MAX3372E/MAX3377E operate at a guaranteed data rate of 230kbps. Slew-rate limiting reduces EMI emissions in all 230kbps devices. The MAX3373E–MAX3376E/MAX3378E/MAX3379E and MAX3390E–MAX3393E operate at a guaranteed data rate of 8Mbps over the entire specified operating voltage range. Within specific voltage domains, higher data rates are possible. (See theTiming Characteristicstable in the full data sheet.)The MAX3372E–MAX3376E are dual level shifters available in 3 x 3 UCSP™, 8-pin TDFN, and 8-pin SOT23 packages. The MAX3377E/MAX3378E/MAX3379E and MAX3390E–MAX3393E are quad level shifters available in 3 x 4 UCSP, 14-pin TDFN, and 14-pin TSSOP packages.ApplicationsCell PhonesCell-Phone CradlesGPSLow-Cost Serial InterfacesLow-Voltage ASIC Level TranslationPortable Communication DevicesPortable POS SystemsSmart Card ReadersSPI, MICROWIRE, and I²C Level TranslationTelecommunications Equipment

The MAX338/MAX339 are monolithic, CMOS analog multiplexers (muxes). The 8-channel MAX338 is designed to connect one of eight inputs to a common output by control of a 3-bit binary address. The dual, 4-channel MAX339 is designed to connect one of four inputs to a common output by control of a 2-bit binary address. Both devices can be used as either a mux or a demux. On-resistance is 400Ω max, and the devices conduct current equally well in both directions.These muxes feature extremely low off leakages (less than 20pA at +25°C), and extremely low on-channel leakages (less than 50pA at +25°C). The new design offers guaranteed low charge injection (1.5pC typ) and electrostatic discharge (ESD) protection greater than 2000V, per method 3015.7. These improved muxes are pin-compatible upgrades for the industry-standard DG508A and DG509A. For similar Maxim devices with lower leakage and charge injection but higher on-resistance, see the MAX328 and MAX329.The MAX338/MAX339 operate from a single +4.5V to +30V supply or from dual supplies of ±4.5V to ±20V. All control inputs (whether address or enable) are TTL compatible (+0.8V to +2.4V) over the full specified temperature range and over the ±4.5V to ±18V supply range. These parts are fabricated with Maxim's 44V silicon-gate process.ApplicationsCommunication SystemsData Acquisition SystemsGuidance and Control SystemsHeads-Up DisplaysMilitary RadiosPBX, PABXSample-and-Hold CircuitsTest Equipment

The MAX3380E/MAX3381E are +2.35V to +5.5V-powered EIA/TIA-232 and V.28/V.24 communication interfaces with low power requirements, high data-rate capabilities, and enhanced electrostatic discharge (ESD) protection on both the TTL and RS-232 sides. The MAX3380E/MAX3381E have two receivers and two transmitters. All RS-232 inputs, outputs, and logic input pins are protected to ±15kV using IEC 1000-4-2 Air-Gap Discharge method and the Human Body Model, and ±8kV using IEC 1000-4-2 Contact Discharge method.The proprietary low-dropout transmitter output stage enables true RS-232 performance from a +3.1V to +5.5V supply with a dual charge pump. The parts reduce the transmitter output levels to RS-232-compatible levels with no increase in supply current for supplies less than +3.1V and greater than +2.35V. The +2.35V to +5.5V operating range is fully compatible with lithium-ion (Li+) batteries. The charge pump requires only four small 0.1µF capacitors for operation.The MAX3380E/MAX3381E transceivers use Maxim's revolutionary AutoShutdown Plus™ feature to automatically enter a 1µA shutdown mode. These devices shut down the on-board power supply and drivers when they do not sense a valid signal transition for 30 seconds on either the receiver or transmitter inputs.The MAX3380E is capable of transmitting data at rates of 460kbps while maintaining RS-232 output levels, and the MAX3381E operates at data rates up to 250kbps. The MAX3381E offers a slower slew rate for applications where noise and EMI are issues. The MAX3380E/MAX3381E have a unique VLpin that allows interoperation in mixed-logic voltage systems down to +1.65V. Both input and output logic levels are referenced to the VLpin. The MAX3380E/MAX3381E are available in a space-saving TSSOP package.ApplicationsCellular Data CablesDigital Still CamerasGPS ReceiversPDA Data Lump Cables
