双单稳多谐振荡器 Dual Monostable Multivibrator

General Description

The MM dual monostable multivibrator is a monolithic complementary MOS integrated circuit. Each multivi

brator features a negative-transition-triggered input and a positive-transition-triggered input, either of which can be used as an inhibit input, and a clear input.

Features

■Wide supply voltage range: 4.5V to 15V

■Guaranteed noise margin: 1.0V

■High noise immunity: 0.45 VCCtyp.

■Low power TTL compatibility: fan out of 2 driving 74L
