The Toshiba TC74AC245FT is an advanced high-speed CMOS octal bus transceiver fabricated with silicon gate and double-layer metal wiring technology. It achieves high-speed operation similar to equivalent Bipolar Schottky TTL while maintaining low CMOS power dissipation. This transceiver is intended for two-way asynchronous communication between data busses. The direction of data transmission is determined by the level of the DIR input, and the enable input (G) can disable the device to isolate the busses.
Key features include a typical propagation delay of 3.9 ns at 5V, a wide operating voltage range from 2V to 5.5V, and low power dissipation with a maximum quiescent current of 8 μA at 25°C. It offers high noise immunity with VNIH and VNIL at 28% VCC minimum, and symmetrical output impedance of ±24 mA minimum, enabling it to drive 50 Ω transmission lines. All inputs are equipped with protection circuits against static discharge or transient excess voltage.
The TC74AC245FT is pin and function compatible with 74F245/640. It is available in a TSSOP package, weighing 0.08 g typically. Note that all floating bus terminals must have their input levels fixed by means of pull-up or pull-down resistors to prevent damage.
