HI3-050616-Channel, 8-Channel, Differential 8-Channel and Differential 4-Channel, CMOS Analog MUXs with Active Overvoltage Protection | Analog Switches, Multiplexers, Demultiplexers | 3 | Obsolete | The HI-506A, HI-507A, HI-508A and HI-509A are analog multiplexers with active overvoltage protection. Analog input levels may greatly exceed either power supply without damaging the device or disturbing the signal path of other channels. Active protection circuitry assures that signal fidelity is maintained even under fault conditions that would destroy other multiplexers. Analog inputs can withstand constant 70VP-Plevels with ±15V supplies. Digital inputs will also sustain continuous faults up to 4V greater than either supply. In addition, signal sources are protected from short circuiting should multiplexer supply loss occur. Each input presents 1kΩ of resistance under this condition. These features make the HI-506A, HI-507A, HI-508A and HI-509A ideal for use in systems where the analog inputs originate from external equipment, or separately powered circuitry. All devices are fabricated with 44V dielectrically isolated CMOS technology. The HI-506A is a single 16-channel multiplexer, the HI-507A is an 8-channel differential multiplexer, the HI-508A is a single 8-channel multiplexer and the HI-509A is a differential 4-channel multiplexer. If input overvoltage protection is not needed the HI-506/507/508/509 multiplexers are recommended. For further information see Application Note AN520. |
HI3-0507Single 16 and 8/Differential 8-Channel and 4-Channel CMOS Analog Multiplexers | Analog Switches, Multiplexers, Demultiplexers | 3 | Obsolete | The HI-506/HI-507 and HI-508/HI-509 monolithic CMOS multiplexers each include an array of sixteen and eight analog switches respectively, a digital decoder circuit for channel selection, voltage reference for logic thresholds, and an enable input for device selection when several multiplexers are present. The Dielectric Isolation (DI) process used in fabrication of these devices eliminates the problem of latchup. DI also offers much lower substrate leakage and parasitic capacitance than conventional junction isolated CMOS (see Application Note AN520). The switching threshold for each digital input is established by an internal +5V reference, providing a guaranteed minimum 2. 4V for logic 1 and maximum 0. 8V for logic 0. This allows direct interface without pullup resistors to signals from most logic families: CMOS, TTL, DTL and some PMOS. For protection against transient overvoltage, the digital inputs include a series 200Ω resistor and diode clamp to each supply. The HI-506 is a single 16-channel, the HI-507 is an 8-channel differential, the HI-508 is a single 8-channel and the HI-509 is a 4-channel differential multiplexer. If input overvoltages are present, the HI-546/HI-547/HI-548/ HI-549 multiplexers are recommended. |
