U74AVC4T245
DESCRIPTION
The UTC U74AVC4T245 is an 4-bit dual supply transceiver that enables bidirectional level translation. The A port is designed to track
X1QFN-16(1.8×2.6)
VCCA. VCCA accepts any supply voltage from 1.2V to 3.6V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.2V to 3.6V. The UTC U74AVC4T245 is optimized to operate with
VCCA/VCCB set at 1.4V to 3.6V. It is operational with VCCA/VCCB as low as 1.2V. 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 UTC U74AVC4T245 device is designed for asynchronous munication 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...
