- Control inputs VIH/VIL levels are referenced to VCCA Voltage, all input pins cannot be suspended

- VCC isolation Feature – if either VCC input is at GND, all are in the high-impedance state

- Fully configurable dual-rail design allows each port to operate over the full 1.65 V to 5.5 V power supply range

- Recommended temperature range: -40°C to 125°C




This 8-bit noninverting bus transceiver uses two separate power-supply rails. The GT74LVC8T245 is optimized to operate with VCCA and VCCB set at 1.65 V to 5.5 V. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.65 V to 5.5 V. The B port is designed to track VCCB. VCCB accepts any supply voltage from1.65 V to 5.5 V. This allows for universal low-voltage bidirectional translation between any of the 1.8 V,2.5 V, 3.3 V, and 5.5 V voltage nodes. The logic levels of the direction-control (DIR) input and the output-enable (OEB) 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 have a logic HIGH or LOW level applied to prevent excess ICC and ICCZ. The GT74LVC8T245 is designed so that the control pins  are supplied by VCCA.
