SN74LVC1G123YEPR

Overview

The SN74LVC1G123YEPR is a single retriggerable monostable multivibrator from the Texas Instruments LVC logic family. It operates within a supply voltage range of 1.65 V to 5.5 V and features Schmitt-trigger inputs for noise immunity. The device provides a low quiescent current of 20 µA maximum and supports output drive currents of ±32 mA. It is housed in an X2SON-8 package, suitable for space-constrained designs, and functions reliably across an industrial temperature range of -40°C to +125°C.

Feature Summary

• Single retriggerable monostable multivibrator configuration
• Schmitt-trigger inputs for enhanced noise filtering
• Low power consumption with minimal static current draw
• Wide operating voltage compatibility for diverse logic levels

Applications

• Pulse width generation and timing control circuits
• Debouncing switches and push-button interfaces
• Frequency division and pulse stretching applications
• Timing delays in digital signal processing systems

Procurement Notes

Verify the specific suffix YEPR against the manufacturer's official datasheet to confirm the X2SON-8 package type and tape-and-reel orientation. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the ordering part number with the latest TI documentation to avoid discrepancies in pinout or electrical characteristics due to manufacturing updates.

Selection Notes

Select this component when a compact, low-power solution for precise timing intervals is required. The Schmitt-trigger input makes it suitable for noisy environments where clean triggering edges are critical. Consider the X2SON-8 package for PCB area optimization compared to larger SOT or SSOP alternatives. Verify that the external timing resistor and capacitor values align with the desired pulse width specifications defined in the technical data.

Part Context

This device belongs to the SN74LVC1G123 series of single monostable multivibrators. It shares functional similarities with other members like the SN74LVC1G123DCTR but differs in packaging. The LVC series is designed for low-voltage CMOS applications, offering performance comparable to older TTL standards while consuming significantly less power. This specific variant utilizes a small footprint package ideal for portable electronics.

Replacement Considerations

Direct substitutes include SN74LVC1G123DCTR and SN74LVC1G123DCUR, which offer identical electrical functionality but utilize different packages such as SC70-5 or SSOP-8. When replacing, ensure the new package fits the existing PCB footprint or adjust the layout accordingly. Verify that the replacement part maintains the same voltage and temperature ratings.
