SN74AHC123AMDREPG4

Overview

The SN74AHC123AMDREPG4 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 and features a maximum quiescent current of 4 uA. The device provides low-level output currents of 8 mA and high-level output currents of -8 mA. Propagation delays are specified at 24.1 ns and 14 ns. It functions reliably across an operating temperature range of -55 °C to +125 °C and is housed in a 16-pin SOIC-Narrow package.

Feature Summary

• Dual retriggerable monostable multivibrator architecture
• Extended industrial temperature operation capability
• Low power consumption design

Applications

• Pulse timing circuits
• Frequency division applications
• Timing delay generation

Procurement Notes

Verify the complete part number including the EPG4 suffix against official Texas Instruments documentation to ensure correct RoHS compliance and specific manufacturing revision. Confirm that the SOIC-Narrow 16-pin package matches your PCB footprint requirements. Ensure the extended temperature rating aligns with your system's thermal environment specifications before finalizing procurement.

Selection Notes

Select this component when dual independent monostable circuits are required in a compact surface-mount form factor. The AHC series offers speed-performance comparable to older technologies while maintaining lower power dissipation. Verify that the 2 V to 5.5 V supply range covers all logic levels in your target application circuit.

Part Context

This device belongs to the SN74AHC123 family of dual retriggerable monostable multivibrators. It is part of the broader AHC logic product line, which utilizes advanced CMOS technology for high-speed operation. The specific AMDREPG4 designation indicates a tape-and-reel packaging format suitable for automated assembly processes.

Replacement Considerations

Check for SN74AHC123ADGVRE4 or SN74AHC123APWRE4 if different package types such as TVSOP-16 or TSSOP-16 are acceptable alternatives.
