74HC4538D Description

Short technical summary and product information.

The 74HC4538D from Toshiba is a high-speed CMOS dual monostable multivibrator. Fabricated with silicon gate C2MOS technology, it offers high-speed operation while maintaining low power dissipation. This device features two trigger inputs, A (positive edge) and B (negative edge), which are valid for slow rise/fall time signals due to their Schmitt trigger nature.

 

The output remains in a monostable state for a time period determined by external resistor (RX) and capacitor (CX). A low level at the CD input breaks this stable state. The device supports retriggering, where a new trigger can extend the monostable period.

 

Key electrical specifications include a propagation delay of 25 ns (typical at 5V), low standby current of 4.0 µA (max), and active current of 350 µA (max) at 25°C. It operates over a wide voltage range of 2V to 6V and has an operating temperature range of -40°C to 125°C.

 

The 74HC4538D is supplied in a 16-SOIC package and is suitable for surface mount applications. It is designed with protection circuits against static discharge or transient excess voltage.
