The TC74HC14AFN from Toshiba is a high-speed CMOS digital integrated circuit featuring six independent Schmitt Inverters. Fabricated with silicon gate C2MOS technology, it offers high-speed operation comparable to LSTTL while maintaining low CMOS power dissipation. Its schmitt trigger function makes it suitable for use as line receivers that can handle slow input signals.
Key electrical characteristics include a typical propagation delay of 11 ns at VCC = 5 V and a low quiescent current of 1 µA maximum at 25°C. The device supports a wide operating voltage range from 2 V to 6 V. It provides a high noise immunity with VH = 1.1 V at VCC = 5 V and has an output drive capability of 10 LSTTL loads. The symmetrical output impedance is |IOH| = IOL = 4 mA minimum.
This component is available in the SOP14-P-300-1.27 package, weighing approximately 0.18 g. It operates within a temperature range of -40°C to 85°C. All inputs are equipped with protection circuits against static discharge or transient excess voltage. The pin configuration and function are compatible with the 74LS14, but the inputs have 25% VCC hysteresis.
Applications for the TC74HC14AFN include signal conditioning, debouncing switches, and interfacing with noisy or slow input signals. Its robust design and performance characteristics make it a reliable choice for various digital logic applications.
