74AHCT32PW,118

Overview

The Nexperia 74AHCT32PW,118 is a quad 2-input OR gate in the 74AHCT logic family. It operates on a supply voltage range of 4.5 V to 5.5 V with TTL-compatible input levels. The device features balanced propagation delays and Schmitt-trigger action on all inputs for high noise immunity. It includes overvoltage tolerant inputs up to 5.5 V, allowing use as translators in mixed-voltage environments. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM). Latch-up performance exceeds 100 mA per JESD 78 Class II Level A. It is specified from -40 °C to +125 °C.

Feature Summary

• TTL-compatible input levels for direct interfacing with TTL devices
• Overvoltage tolerant inputs allow operation in mixed voltage environments
• Schmitt-trigger action on all inputs provides high noise immunity

Applications

• Translators in mixed voltage environments
• General-purpose logic applications requiring TTL compatibility
• Signal conditioning with high noise immunity requirements

Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature range. Confirm that the component status is active for production. Check for any recent Product Change Notifications regarding packaging or assembly updates. Ensure compliance with RoHS directives and REACH regulations for the target market.

Selection Notes

Select this part when TTL-level inputs are required alongside CMOS output drive capabilities. The 74AHCT series ensures compatibility with legacy TTL systems while offering improved speed and lower power consumption compared to standard 74HC variants. Verify that the operating voltage remains within the 4.5 V to 5.5 V range for proper functionality.

Part Context

This component belongs to the 74AHC/AHCT logic family, which combines the high-speed CMOS technology with the compatibility of TTL inputs. The 'PW' suffix indicates the TSSOP14 plastic thin shrink small outline package. The '118' suffix typically denotes tape and reel packaging, though verification against the manufacturer's current ordering information is recommended.

Replacement Considerations

Direct replacements include other manufacturers' 74AHCT32 parts in TSSOP14 packages. Cross-reference with 74HC32 only if TTL input thresholds are not strictly required. Verify pinout compatibility and electrical characteristics before substitution.
