JIANGSU CHANGJING ELECTRONICS TECHNOLOGY CO., LTD. Dual Retriggerable Monostable Multivibrator with Reset CJ74HC/HCT123 Logic 1 Introduction 3 Features The CJ74HC/HCT123 are high-speed Si-gate CMOS devices and are pin compatible with Low-power • DC triggered from active HIGH or active LOW inputs Schottky TTL (LSTTL). • Retriggerable for very long pulses up to 100% The CJ74HC/HCT123 are dual duty factor retriggerable monostable multivibrators with output pulse width control by three methods: 1. The basic pulse is programmed by selection of an • Direct reset terminates output pulse • Specified from -40°C to +125°C external resistor (REXT) and capacitor (CEXT). 4 Applications 2. Once triggered, the basic output pulse width may be • Blu-ray Players and Home Theaters extended by retriggering the gated active LOW-going edge input (/nA) or the active HIGH-going edge input • Digital Video Cameras (DVC) • GPS: Personal Navigation Devices (nB). By repeating this process, the output pulse period • Wireless Headsets, Keyboard, and Mice (nQ=HIGH, /nQ=LOW) can be made as long as desired. Alternatively an output delay can be terminated at any time by a LOW-going edge on input /nRD, which also inhibits the triggering. 3. An internal connection from /nRD to the input gates makes it possible to trigger the circuit by a HIGH-going signal at input /nRD. 2 Available Packages PART NUMBER CJ74HC123 CJ74HCT123 REXT/CEXT PACKAGE SOP16 nA TSSOP16 nB SOP16 nRD TSSOP16 S T Q nQ Q nQ RD Note: For all available packages, please refer to the part Orderable Information. www.jscj-elec.com CEXT Logic diagram 1 Rev. – 1.0 PDF
