SN74AHC123AMDREP

Overview

The SN74AHC123AMDREP is a dual retriggerable monostable multivibrator from the Texas Instruments AHC logic series. It operates within a supply voltage range of 2 V to 5.5 V, supporting standard voltages of 2.5 V, 3.3 V, and 5 V. The device features propagation delays of 24.1 ns and 14 ns, with a maximum quiescent current of 4 uA. It provides output drive currents of 8 mA (low) and -8 mA (high). Operating temperatures span from -55°C to +125°C. The component is housed in a 16-pin SOIC-Narrow package.

Feature Summary

• Dual retriggerable monostable multivibrator configuration
• Extended military-grade temperature operation capability
• CMOS technology for low power consumption

Applications

• Military electronic systems requiring enhanced reliability
• Pulse timing and delay generation circuits
• Frequency division applications
• Timing error correction loops

Procurement Notes

Verify the specific suffix 'REP' indicates MIL-enhanced qualification status against the official manufacturer datasheet. Confirm RoHS compliance details as listed in the product specifications. Ensure the SOIC-Narrow-16 package dimensions match the design constraints. Validate that the operating temperature range meets the environmental requirements of the target application.

Selection Notes

Select this component when dual independent monostable circuits are required in a compact surface-mount format. The AHC series offers speed-performance comparable to ALS while maintaining CMOS low-power characteristics. Consider the extended temperature range if the application involves harsh environments. Verify input compatibility with the system logic levels before integration.

Part Context

This part belongs to the SN74AHC123A family of dual retriggerable monostable multivibrators. The 'AMDREP' designation specifies the SOIC-Narrow-16 package and MIL-enhanced processing. It serves as a robust timing solution for aerospace and defense electronics where standard commercial parts may not suffice for extreme thermal conditions.

Replacement Considerations

SN74AHC123AM is the non-rep variant. SN74AHC123ADREP is the wider SOIC package equivalent.
