TC74HC123APNEWF

Overview

The TC74HC123APNEWF is a dual retriggerable monostable multivibrator manufactured by Toshiba Semiconductor and Storage. It operates within a supply voltage range of 2.0 V to 6.0 V and features propagation delays of 210 ns, 42 ns, and 36 ns. The device provides output currents of 5.2 mA for both high and low states. It is housed in a 16-pin PDIP package designed for through-hole mounting. The component functions reliably across an operating temperature range from -40 °C to +85 °C.

Feature Summary

• Dual retriggerable monostable multivibrator architecture
• Schmitt trigger inputs on nA and nB terminals for noise tolerance
• Direct reset capability to terminate output pulses immediately
• CMOS logic compatibility with LSTTL pinout standards

Applications

• Pulse width modulation circuits
• Timing delay generation systems
• Debouncing switches for digital inputs

Procurement Notes

Verify the specific suffix (NEW,F) against official Toshiba documentation to confirm exact manufacturing revisions and compliance status. Ensure the procurement channel sources genuine components to avoid counterfeit risks. Confirm that the PDIP-16 through-hole package matches the target PCB footprint requirements before finalizing orders.

Selection Notes

Select this component when a dual-channel timing solution with Schmitt trigger input noise immunity is required. It is suitable for applications needing direct reset functionality and retriggerable pulse extension. Verify that the 2V to 6V supply range aligns with the system power rails and that the 5.2mA drive current meets load requirements.

Part Context

This part belongs to the TC74HC123 series of CMOS logic integrated circuits. It is compatible with the standard 74HC123 function set while adhering to JEDEC standards. The device utilizes Toshiba's silicon gate C²MOS technology to achieve high-speed operation combined with low power consumption characteristics typical of the HC logic family.

Replacement Considerations

Standard 74HC123 equivalents from other manufacturers may serve as functional substitutes if pinouts and electrical specifications match. Verify that alternative parts support the same retriggerable operation and Schmitt trigger input requirements.
