TC74VHCT244AF Description

Short technical summary and product information.

The TC74VHCT244AF is an advanced high-speed CMOS octal bus buffer from Toshiba, fabricated using silicon gate C2MOS technology. It achieves high-speed operation comparable to bipolar Schottky TTL while maintaining low CMOS power dissipation. This non-inverting buffer features two active-low output enables and is designed for applications such as 3-state memory address drivers.

 

Key electrical characteristics include a typical propagation delay of 6.1 ns at 5V VCC and a maximum supply current of 4 μA at 25°C. The inputs are compatible with TTL voltage levels (VIL max 0.8V, VIH min 2.0V). The device offers power-down protection on all inputs and outputs, and can interface between 3.3V and 5V systems.

 

Available in multiple package types including SOP20, TSSOP20, and VSSOP20, the TC74VHCT244AF is suitable for various board space requirements. Its input and output circuits allow for 0 to 5.5V to be applied without regard to the supply voltage, preventing device destruction due to mismatched voltages.
