74HCT1G14GW,125

Overview

The Nexperia 74HCT1G14GW,125 is a single inverter with Schmitt-trigger input housed in a 5-TSSOP package. It operates within a supply voltage range of 4.5V to 5.5V and supports an ambient temperature range from -40°C to +125°C. The device features TTL-level inputs, ensuring compatibility with standard logic families. Key electrical parameters include a maximum propagation delay of 51ns at 5V with 50pF load capacitance, static current consumption of up to 20µA, and output drive capabilities of 2mA for both high and low states.

Feature Summary

• Schmitt-trigger input action transforms slowly changing signals into sharply defined, jitter-free outputs
• TTL-level input thresholds ensure direct interface compatibility with standard digital logic systems
• Input clamp diodes enable safe interfacing with voltages exceeding the supply rail using current limiting resistors

Applications

• Wave and pulse shapers
• Astable multivibrators
• Monostable multivibrators

Procurement Notes

Verify the specific ordering suffix '125' against the manufacturer's latest documentation to confirm packaging details and marking codes. Ensure that the TSSOP5 (SOT353-1) footprint matches the target PCB design. Confirm RoHS3 compliance status and moisture sensitivity level requirements prior to final procurement authorization.

Selection Notes

Select this component when TTL-compatible logic levels are required alongside noise immunity provided by Schmitt triggers. The wide operating temperature range makes it suitable for industrial environments. Verify that the 51ns propagation delay meets the timing constraints of the specific application circuit before finalizing the design.

Part Context

This part belongs to the Nexperia 74HCT1G series of single-gate CMOS logic devices. It is designed as a compact solution for signal conditioning in space-constrained applications. The HCT designation indicates High-speed CMOS technology with TTL-compatible inputs, bridging the gap between older logic standards and modern low-power CMOS implementations.

Replacement Considerations

Check for equivalent parts such as the 74HC1G14 variant if CMOS input levels are acceptable instead of TTL.
