74HC1G14GW,165

Overview

The Nexperia 74HC1G14GW,165 is a single inverter with Schmitt-trigger input housed in a TSSOP5 (SOT353-1) package. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range from -40 °C to +125 °C. The device features CMOS low power dissipation, high noise immunity, and unlimited input rise and fall times. Propagation delay is typically 11 ns at 6.0 V with a 50 pF load. Input levels adhere to CMOS standards, and the component includes clamp diodes for interfacing with voltages exceeding VCC.

Feature Summary

• Schmitt-trigger inputs transform slowly changing signals into sharply defined jitter-free output signals
• Inputs include clamp diodes enabling current limiting resistors for voltages exceeding VCC
• High noise immunity with balanced propagation delays and symmetrical output impedance

Applications

• Wave and pulse shapers
• Astable multivibrators
• Monostable multivibrators

Procurement Notes

Verify the specific ordering suffix '165' against official Nexperia documentation, as standard listings often utilize suffixes like '125'. Confirm that the TSSOP5 package variant matches the required footprint dimensions and pin configuration for the target PCB layout. Ensure compliance with RoHS3 and REACH regulations as specified in the product data sheet.

Selection Notes

Select this component when a single inverter with hysteresis is required for noisy environments or slow signal transitions. The wide supply voltage range up to 6.0 V allows flexibility in system design compared to standard 5V-only logic. Verify that the CMOS input levels are compatible with the driving source voltage levels.

Part Context

This part belongs to the Nexperia 74HC family of high-speed CMOS logic devices. The 74HC1G14 series specifically provides single-gate inverters with Schmitt-trigger functionality. It is designed for general-purpose digital applications requiring noise immunity and signal conditioning in compact surface-mount packages.

Replacement Considerations

Direct replacements include the 74HC1G14GW,125 which shares the same functional specifications and TSSOP5 package. Other variants such as the 74HCT1G14 offer TTL-compatible input levels but require a narrower supply voltage range.
