74AHCT14PW,112

Overview

The Nexperia 74AHCT14PW,112 is a hex inverting Schmitt trigger belonging to the AHCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and accepts TTL input levels. The device features overvoltage tolerant inputs up to 5.5 V, ensuring compatibility in mixed-voltage environments. It provides balanced propagation delays and high noise immunity with specified performance from -40 °C to +125 °C.

Feature Summary

• Hex inverter configuration with Schmitt-trigger inputs for signal conditioning
• TTL-compatible input levels for direct interfacing with legacy logic systems
• Overvoltage tolerant inputs allowing operation in mixed voltage environments

Applications

• Wave and pulse shapers
• Astable multivibrators
• Monostable multivibrators

Procurement Notes

Verify the specific ordering suffix

Selection Notes

Select this component when TTL-level interface is required alongside Schmitt-trigger action. The AHCT series ensures CMOS low power dissipation while maintaining compatibility with standard TTL logic families. Verify that the operating environment remains within the specified temperature range and supply voltage limits.

Part Context

This part belongs to the 74AHC/AHCT logic family, which combines the high speed of AHC technology with the TTL-compatible input levels of HCT devices. The PW suffix indicates a TSSOP14 package (SOT402-1), suitable for surface-mount applications requiring a compact footprint with 14 leads.

Replacement Considerations

Direct pin-compatible replacements include the 74AHC14PW and 74HCT14PW. Ensure the alternative matches the required input logic level (CMOS vs. TTL) and verify package compatibility.
