CD74HC123NSR

Multivibrators Overview

The CD74HC123NSR is a high-speed CMOS logic dual retriggerable monostable multivibrator with resets, manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and features a propagation delay of 25 ns. The device provides buffered Q and Q outputs with output currents of 5.2 mA for both high and low states. It supports triggering from the leading or trailing edge and includes an overriding reset function that terminates the output pulse. The component is housed in a 16-SOIC package and functions reliably across an operating temperature range of -55°C to 125°C.

Multivibrators Procurement Notes

Verify the specific suffix NSR indicates tape-and-reel packaging when sourcing. Confirm RoHS3 compliance status as per the latest manufacturer documentation. Check for obsolescence notices or product change notifications (PCN) regarding manufacturing site changes. Ensure the supplier provides valid traceability data for the 16-SOIC package variant.

Multivibrators Selection Notes

Select this component for applications requiring dual independent monostable circuits in a compact surface-mount package. Consider the 25 ns propagation delay for high-speed timing requirements. Verify that the 2 V to 6 V supply range aligns with the system power rails. Ensure the design accommodates the -55°C to 125°C operating temperature range if used in industrial environments.

Multivibrators Part Context

This part belongs to the Texas Instruments 74HC series of high-speed CMOS logic devices. It is functionally compatible with other 74HC123 variants but differs in packaging and reel specifications. The NSR suffix specifically denotes the tape-and-reel format suitable for automated assembly processes.
