TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic

TC74HC14AP, TC74HC14AF

Hex Schmitt Inverter

The TC74HC14A is a high speed CMOS SCHMITT

INVERTER fabricated with silicon gate C2MOS technology.

It achieves the high speed operation similar to equivalent

LSTTL while maintaining the CMOS low power dissipation. Pin

configuration and function are the same as the TC74HC04A but

the inputs have 25% VCC hysteresis and with its schmitt trigger

function, the TC74HC14A can be used as a line receivers which

will receive slow input signals.

All inputs are equipped with protection circuits against static

discharge or transient excess voltage.

Features

• High speed: tpd = 11 ns (typ.) at VCC = 5 V

• Low power dissipation: ICC = 1 μA (max) at Ta = 25°C

• High noise immunity: VH = 1.1 V at VCC = 5 V

• Output drive capability: 10 LSTTL loads

• Symmetrical output impedance: |IOH| = IOL = 4 mA (min)

• Balanced propagation delays: tpLH ∼− tpHL

• Wide operating voltage range: VCC (opr) = 2 to 6 V

• Pin and function compatible with 74LS14
