The CD54HC4538F from Texas Instruments is a dual retriggerable and resettable monostable precision multivibrator designed for fixed voltage timing applications. The timing and accuracy are controlled by external resistors (R X ) and capacitors (C X ), allowing for a wide range of output pulse widths.
This device operates within a temperature range of -55°C to 125°C and is housed in a 16-pin CDIP (J) package. It offers features such as triggering from either the leading or trailing edge of an input pulse, separate resets, and buffered outputs. The propagation delays from trigger and reset inputs to the output are independent of R X and C X .
Suitable for various timing circuits, the CD54HC4538F provides flexibility through its adjustable pulse widths and Schmitt trigger inputs on A and B\ inputs. Unused 'A' inputs should be tied to GND, and unused 'B\' inputs should be tied to V CC . On power-up, the IC is reset.
