TC74HC30AF

The Toshiba TC74HC30AF is a silicon monolithic CMOS digital integrated circuit featuring an 8-input NAND gate. Fabricated with silicon gate C2MOS technology, it achieves high-speed operation comparable to LSTTL while maintaining low CMOS power dissipation. The internal circuit includes a buffer output stage, providing high noise immunity and stable output characteristics. All inputs are equipped with protection circuits against static discharge or transient excess voltage.

This device operates over a wide voltage range of 2 V to 6 V and features a typical propagation delay of 12 ns at 5 V. Its low power dissipation is characterized by a maximum supply current of 1 µA at 25°C. The TC74HC30AF is pin and function compatible with the 74LS30. It is available in DIP14 and SOP14 packages, with surface mount options.

Key electrical characteristics include a minimum high-level output voltage of 1.9 V at 2.0 V VCC and 4.4 V at 4.5 V VCC, with an output drive capability of 10 LSTTL loads. Input rise and fall times are specified up to 1000 ns at 2.0 V, decreasing to 400 ns at 6.0 V. The operating temperature range is from -40°C to 85°C.
