74AHCT1G14GW,125

Overview

The Nexperia 74AHCT1G14GW,125 is a single inverting Schmitt trigger integrated circuit manufactured by Nexperia USA Inc. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL input switching levels. The device is housed in a TSSOP5 plastic thin shrink small outline package (SOT353-1) with five leads and a body width of 1.25 mm. It supports an ambient operating temperature from -40 °C to +125 °C. Key electrical characteristics include a maximum propagation delay of 9.0 ns at 5.5 V with a 15 pF load, high noise immunity, and overvoltage tolerant inputs up to 5.5 V.

Feature Summary

• Incorporates Schmitt-trigger inputs to provide hysteresis for improved noise immunity and signal conditioning.
• Features overvoltage tolerant inputs capable of handling voltages up to 5.5 V, facilitating use in mixed-voltage environments.
• Provides symmetrical output impedance and CMOS low power dissipation characteristics.
• Includes robust ESD protection exceeding 2000 V per the Human Body Model and 1000 V per the Charged Device Model.

Applications

• Wave and pulse shapers
• Astable multivibrators
• Monostable multivibrators

Verify the specific ordering suffix

Selection Notes

Select this component when TTL-compatible logic levels are required in a 5 V system. The AHCT series ensures compatibility with standard TTL outputs while offering CMOS performance benefits. Ensure the design accommodates the specified 4.5 V to 5.5 V supply range and verify that the TSSOP5 package dimensions fit the PCB layout constraints.

Part Context

This part belongs to the Nexperia 74AHC/AHCT1G1x series of single-function logic gates. The 'AHCT' designation indicates Advanced High-speed CMOS technology with TTL-compatible input thresholds, distinguishing it from the standard AHC series which uses CMOS input levels. The 'GW' suffix identifies the TSSOP5 package variant, while '1G14' denotes the single inverter with Schmitt trigger function within the family.

Replacement Considerations

Direct functional equivalents within the same package include the 74AHC1G14GW,125, though it requires CMOS input levels rather than TTL. Other package variants such as 74AHCT1G14GV,125 (SC-74A) or 74AHCT1G14GZ,125 (XSON5) offer the same electrical functionality but require different footprint considerations.
