74HCT123DB,112

Multivibrators Overview

The 74HCT123DB,112 is a dual retriggerable monostable multivibrator manufactured by Nexperia USA Inc. It operates within a supply voltage range of 4.5 V to 5.5 V and features Schmitt-trigger inputs for noise immunity. The device provides two independent circuits with a propagation delay of 77 ns. It supports surface mount installation in a 16-SSOP package and functions reliably across an operating temperature range from -40 °C to +125 °C.

Multivibrators Feature Summary

• Dual retriggerable monostable multivibrator configuration
• Schmitt-trigger action on inputs for slow signal tolerance
• Direct reset capability to terminate output pulses

Multivibrators Applications

• Pulse width generation and timing circuits
• Debouncing switches or contacts
• Frequency division and pulse stretching

Multivibrators Procurement Notes

This component is officially classified as End-of-Life (EOL) and is no longer manufactured by Nexperia. Procurement channels indicate restricted availability or discontinuation status. Buyers must verify current stock levels with authorized distributors and consider the long-term viability of this part for new designs due to its discontinued production status.

Multivibrators Selection Notes

Select this component only if legacy compatibility with the 74HCT123 logic family is required. Verify that the 16-SSOP package dimensions fit the target PCB layout. Ensure the design accounts for the TTL input level requirements specific to the HCT series rather than standard HC CMOS levels.

Multivibrators Part Context

This part belongs to the 74HCT123 series of dual monostable multivibrators. It is distinct from other packages like TSSOP or SOIC variants offered by Nexperia. The 'DB' suffix specifically denotes the SSOP-16 package type, differentiating it from other physical form factors within the same logical function family.

Multivibrators Replacement Considerations

Publicly confirmed substitute part numbers include 74HCT123PW,118 (TSSOP-16 package). Other potential alternatives may exist from different manufacturers, but direct pin-compatible replacements should be verified against official datasheets.
