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 V_CCA, while the B port is designed to track V_CCB. V_CCA and V_CCB can accept any supply voltage from 1.2 V to 3.6 V.

If either V_CC is switched off (V_CCA = 0 V and/or V_CCB = 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.
