SCES553H May 2004 – November 2020 SN74AVC32T245
This 32-bit noninverting bus transceiver uses two separate, configurable power-supply rails. The SN74AVC32T245 device is optimized to operate with VCCA/VCCB set from 1.4 V to 3.6 V. It is operational with VCCA/VCCB as low as 1.2 V. The A port is designed to track VCCA. VCCA and accepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to track VCCB. VCCB and 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 SN74AVC32T245 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 disable the outputs so the buses are effectively isolated.
The SN74AVC32T245 is designed so that the control pins (1DIR, 2DIR, 3DIR, 4DIR, 1 OE, 2 OE, 3 OE, and 4 OE) are supplied by VCCA.
