SN74AVC6T622PWR Datasheet PDF - TI

●The SN74AVC6T622PWR is a Voltage Level Transceiver for interfacing 1.8V 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 1.8V logic levels, the SN74AVC6T622 device can be used to bridge the gap between legacy 3.3V AC"97 codecs and AC"97 controllers that are now operating at 1.8V. This 6-bit wide 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. VCCA and VCCB can accept any supply voltage from 1.2 to 3.6V. If either VCC is switched off (VCCA = 0V and/or VCCB = 0V), all outputs are placed in the high-impedance state to conserve power.

● Configurable I/O switching levels with dual-supply pins
