74AVC6T622Audio Codec AC'97 Voltage-Translation Transceiver | CODECS | 3 | Active | The SN74AVC6T622 is a voltage-level transceiver for interfacing 1.8 V audio codec (AC’97) controllers, the audio/analog modem functionality found in personal computers, with 3.3V AC’97 codec links. With the digital switching levels of today’s AC’97 codecs lowering to 1.8-V logic levels, the SN74AVC6T622 device can be used to bridge the gap between legacy 3.3-V AC’97 codecs and AC’97 controllers that are now operating at 1.8 V. The 6-bit wide SN74AVC6T622 device complies with the AC’97 electrical interface (both levels and timing) specification.
Two supply-voltage pins allow the A-port and B-port input switching thresholds to be configured separately. The A port is designed to track VCCA, while the B port is designed to track VCCB. VCCAand VCCBcan accept any supply voltage from 1.2 V to 3.6 V.
If either VCCis switched off (VCCA= 0 V and/or VCCB= 0 V), all outputs are placed in the high-impedance state to conserve power.
The SN74AVC6T622 is available in two 0.5-mm-pitch ball grid array (BGA) packages. The 20-ball package has dimensions of 3 mm × 2.5 mm, and the 24-ball package measures 3 mm × 3 mm. Memory cards are widely used in mobile phones, PDAs, digital cameras, personal media players, camcorders, set-top boxes, etc. Low static power consumption and small package size make the SN74AVC6T622 an ideal choice for these applications.

74AVC8T245Automotive Catalog 8-Bit Dual-Supply Bus Transceiver w/ Configurable Voltage Transl., 3-State Output | Logic | 12 | Active | This 8-bit noninverting bus transceiver uses two separate configurable power-supply rails. The SN74AVC8T245 is optimized to operate with V CCA/V CCB set at 1.4 V to 3.6 V. The device is operational with V CCA and V CCB as low as 1.2 V. The A port is designed to track V CCA. V CCA accepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to track V CCB. V CCB accepts any supply voltage from 1.2 V to 3.6 V. This allows for universal low-voltage bidirectional translation between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, and 3.3-V voltage nodes.
The SN74AVC8T245 is designed for asynchronous communication between data buses. The device transmits data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable ( OE) input can be used to disable the outputs so the buses are effectively isolated.
The SN74AVC8T245 is designed so that the control pins (DIR and OE) are supplied by V CCA.
The SN74AVC8T245 is compatible with a single-supply system and can be replaced later with a ’245 function, with minimal printed circuit board redesign.
This device is fully specified for partial-power-down applications using I off. The I off circuitry disables the outputs, thus preventing damaging current backflow through the device when it is powered down.
The V CC isolation feature allows both ports to be in the high-impedance state when either V CC input is at GND.
To put the device into the high-impedance state during power up or power down, tie OE to V CC through a pullup resistor; the current-sinking capability of the driver determines the minimum value of the resistor.

74AVCA406MMC, SD, Memory Stick, Smart Media, and XD-Picture Card Voltage Translation Transceiver | Translators, Level Shifters | 8 | Active | The SN74AVCA406 is a transceiver for interfacing microprocessors with MultiMediaCards (MMCs), secure digital (SD) cards, Memory Stick™ compliant products, SmartMedia cards, or xD-Picture Cards™. It integrates high ESD protection, which eliminates the need for external ESD diodes. Two supply-voltage pins allow the A-port and B-port input switching thresholds to be configured separately. The A port is designed to track VCCA, while the B port is designed to track VCCB0and VCCB1. VCCA,VCCB0and VCCB1can accept any supply voltage from 1.4 V to 3.6 V.
Memory card standards recommend high ESD protection for devices that connect directly to the external memory card. To meet this need, the SN74AVCA406 incorporates ±15-kV air-gap discharge and ±8-kV contact discharge protection on the card side. If VCCB0and VCCB1are switched off (no card inserted), the A-port outputs are placed in the high-impedance state to conserve power.
The SN74AVCA406 enables system designers to easily interface low-voltage microprocessors to different memory cards operating at higher voltages. The mode (MODE0 and MODE1) pins are used to configure the device to interface with different types of cards.
The SN74AVCA406 is offered in the 48-ball MicroStar Jr.™ ball grid array (BGA) package. This package has dimensions of 4 × 4 mm, with a 0.5-mm ball pitch for effective board-space savings.
