DESCRIPTION/ORDERING INFORMATION
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.

SCES706A – SEPTEMBER 2008 – REVISED MARCH 2009............................................................................................................................................. www.ti.com
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 V to 3.6 V.
If either VCC is 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.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
The input voltage and output negative-voltage ratings may be exceeded if the input and output current ratings are observed.
The output positive-voltage rating may be exceeded up to 4.6 V maximum if the output current rating is observed.
The package thermal impedance is calculated in accordance with JESD 51-7.
The package thermal impedance is calculated in accordance with JESD 51-5.

B. Waveform 1 is for an output with internal conditions such that the output is low, except when disabled by the output control.
Waveform 2 is for an output with internal conditions such that the output is high, except when disabled by the output control.
C. All input pulses are supplied by generators having the following characteristics: PRRv10 MHz, ZO = 50 Ω, dv/dt ≥ 1 V/ns.
D. The outputs are measured one at a time, with one transition per measurement.
E. tPLZ and tPHZ are the same as tdis.
F. tPZL and tPZH are the same as ten.
G. tPLH and tPHL are the same as tpd.
H. VCCI is the VCC associated with the input port.
I. VCCO is the VCC associated with the output port.

The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.

RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
