74HCT123D,653

The 74HCT123D,653 from Nexperia is a dual retriggerable monostable multivibrator designed for versatile timing applications. It offers a wide supply voltage range from 2.0 V to 6.0 V, with specific operation noted between 4.5 V and 5.5 V. The device features a propagation delay of 77 ns and includes Schmitt-trigger action on its inputs, providing tolerance to slower input rise and fall times.

This monostable multivibrator is housed in a 16-SOIC package, suitable for surface mount applications. It is specified for operation across a temperature range of -40°C to 125°C. The dual nature of the device allows for independent timing circuits, programmable by external components. Its retriggerable design enables the extension of output pulses, supporting up to a 100% duty factor.

Key features include low power dissipation characteristic of CMOS technology and high noise immunity. The device also incorporates a direct reset function to terminate the output pulse. Its latch-up performance exceeds 100 mA per JESD 78 Class II Level B, and ESD protection is provided for both HBM and CDM classes.
