74AHCT1G14GW,165

Overview

The Nexperia 74AHCT1G14GW,165 is a single inverter with Schmitt-trigger inputs housed in a TSSOP5 (SOT353-1) package. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL input switching levels. The device provides overvoltage tolerant inputs up to 5.5 V, enabling use as translators in mixed-voltage environments. It exhibits high noise immunity, CMOS low power dissipation, and symmetrical output impedance. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM). Latch-up performance exceeds 100 mA per JESD78 Class II Level A. Operating temperature ranges from -40 °C to +125 °C.

Feature Summary

• Schmitt-trigger action transforms slowly changing input signals into sharply defined jitter-free output signals.
• Overvoltage tolerant inputs allow direct interfacing with voltages exceeding the supply voltage.
• Suitable for wave and pulse shaping applications due to high noise immunity.

Applications

• Wave and pulse shapers
• Astable multivibrators
• Monostable multivibrators

Procurement Notes

Verify the specific ordering suffix '165' against official Nexperia documentation, as standard listings typically utilize suffixes such as '125'. Confirm package type SOT353-1 matches design requirements. Ensure compatibility with 4.5 V to 5.5 V supply rails and TTL logic levels. Check for automotive qualification status if required for the target application environment.

Selection Notes

Select this component when TTL-compatible input thresholds are required at 5 V operation. The Schmitt-trigger input is essential for cleaning noisy or slow-rising digital signals. Verify that the TSSOP5 footprint aligns with PCB layout constraints. Consider the overvoltage tolerance feature if interfacing with higher voltage domains without level shifters.

Part Context

This part belongs to the Nexperia 74AHC/AHCT1G14 family of single inverters. The AHCT variant specifically targets 5 V systems with TTL input levels, distinguishing it from the HC series which uses CMOS levels. The GW suffix indicates the TSSOP5 plastic thin shrink small outline package. This family supports mixed-voltage translation tasks due to its robust input characteristics.

FAQ

What is the function of the Schmitt trigger in this inverter?

The Schmitt trigger input converts slowly changing input signals into sharply defined output signals, eliminating jitter caused by noise or slow rise/fall times.

Can this device interface with voltages higher than VCC?

Yes, the inputs are overvoltage tolerant up to 5.5 V, allowing them to accept voltages higher than the supply voltage VCC.
