MM74C14

Hex Schmitt Trigger

General Description

The MM74C14 Hex Schmitt Trigger is a monolithic comple-

mentary MOS (CMOS) integrated circuit constructed with

N- and P-channel enhancement transistors. The positive

and negative going threshold voltages VT+ and VT−, show

low variation with respect to temperature (typ. 0.0005V/°C

at VCC = 10V), and hysteresis, VT+ − VT− ≥ 0.2 VCC is guar-

anteed.

All inputs are protected from damage due to static dis-

charge by diode clamps to VCC and GND.

Features

s Wide supply voltage range: 3.0V to 15V

s High noise immunity: 0.70 VCC (typ.)

s Low power: TTL compatibility:

0.4 VCC (typ.) 0.2 VCC guaranteed

s Hysteresis: 0.4 VCC (typ.): 0.2 VCC guaranteed
