DUAL MONOSTABLE MULTIVIBRATOR

Description The HCC4000B series is composed of close to 80 monolithic types built with Metal Oxide Complementary technology. It provides Designers with high voltage noise tolerant complete Logic series. It radiation hardness and immunity to Heavy Ions make this series to be usable in the

Dual retriggerable precision monostable multivibrator

GENERAL DESCRIPTION The 74HC/HCT4538 are high-speed Si-gate CMOS devices and are pin compatible with “4538” of the “4000B” series. They are specified in compliance with JEDEC standard no. 7A. FEATURES • Separate reset inputs • Triggering from leading or trailing edge • Output capa

Dual precision monostable multivibrator

DESCRIPTION The HEF4538B is a dual retriggerable-resettable monostable multivibrator. Each multivibrator has an active LOW trigger/retrigger input (I0), an active HIGH trigger/retrigger input (I1), an overriding active LOW direct reset input (CD), an output (O) and its complement (O), and two pin
