The Toshiba TC74VHCT245AFT is an ultra-high-speed CMOS octal bus transceiver built using silicon-gate CMOS technology. It offers low power consumption while achieving high-speed operation comparable to high-speed Schottky TTL. The device features Q&Q buffers to significantly reduce noise during switching.
Designed for connecting to bidirectional data buses of CPUs and other devices, this transceiver accelerates data transmission. The DIR input controls the direction of data flow between the A and B buses, while the G input enables or disables the outputs, placing them in a high-impedance state. All input/output terminals are protected against damage from overvoltage conditions, allowing for 5V input and output voltages regardless of the power supply voltage. This power-down protection feature enables applications such as 2-power supply interfaces, battery backup circuits, and live-board insertion.
Key electrical characteristics include a typical propagation delay of 4.9 ns at 5V, a maximum supply current of 4 µA at 25°C, and TTL-level inputs (VIL max 0.8V, VIH min 2.0V). It operates over a temperature range of -40°C to 85°C and requires a supply voltage of 4.5V to 5.5V. The device is available in a surface-mount SOP20 package.
