SN74AVC4T774RGYR Datasheet PDF - TI

●The SN74AVC4T774RGYR is a 4-bit dual-supply Bus Transceiver with configurable voltage-level shifting and 3-state outputs. The non-inverting bus transceiver uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.2 to 3.6V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.2 to 3.6V. It is optimized to operate with VCCA/VCCB set at 1.4 to 3.6V. It is operational with VCCA/VCCB as low as 1.2V. 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 in the high-impedance mode. The device transmits data from the A bus to the B bus when the B outputs are activated and from the B bus to the A bus when the A 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.

● Designed for asynchronous communication between data buses

● IOFF Supports partial power-down-mode operation

● Control inputs VIH/VIL levels are referenced to VCCA voltage

● Each channel has an independent DIR control input

● Latch-up performance exceeds 100mA per JESD 78, class II

● Fully configurable dual-rail design allows port to operate over full 1.2 to 3.6V power-supply range

● I/Os are 4.6V tolerant

● Green product and no Sb/Br
