Description
General part information
SN74AVCH4T245-Q1 Series
This 4-bit noninverting bus transceiver uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.08V to 3.6V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.08V to 3.6V. The SN74AVCH4T245-Q1 is optimized to operate with VCCA/VCCB set at 1.08V to 3.6V. It is operational with VCCA/VCCB as low as 1.08V. This allows for universal low voltage bidirectional translation between any of the 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V voltage nodes.
The SN74AVCH4T245-Q1 is designed for asynchronous communication between two data buses. The logic levels of the direction-control (DIR) input and the output-enable (OE) input activate either the B-port outputs or the A-port outputs or place both output ports into the high-impedance mode. The device transmits data from the A bus to the B bus when the B-port outputs are activated, and from the B bus to the A bus when the A-port outputs are activated. The input circuitry on both A and B ports is always active and must have a logic HIGH or LOW level applied to prevent excess ICC and ICCZ.
The SN74AVCH4T245-Q1 device control pins (1DIR, 2DIR, 1OE, and 2OE) are supplied by VCCA.
