Product Summary

The 74HC4538N is a high-speed Si-gate CMOS device and is pin compatible with 4538 of the 4000B series. It is specified in compliance with JEDEC standard no. 7A. The 74HC4538N is dual retriggerable-resettable monostable multivibrator. Each multivibrator has an active LOW trigger/retrigger input (nA0), an active HIGH trigger/retrigger input (nA1) , an overriding active LOW direct reset input (nRD), an output (nQ) and its complement (nQ), and two pins (nCTC and nRCTC) for connecting the external timing components Ct and Rt.
