Overview
The Nexperia 74AHCT32D,112 is a quad 2-input OR gate in the 74AHCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and accepts TTL-level inputs. The device features overvoltage tolerant inputs up to 5.5 V, Schmitt-trigger action on all inputs, and balanced propagation delays. It is housed in an SO14 (SOT108-1) package with a body width of 3.9 mm. The component supports ambient temperatures from -40 °C to +125 °C and includes ESD protection exceeding 2000 V (HBM) and 1000 V (CDM).
Feature Summary
- TTL-compatible input levels for direct interfacing with Transistor-Transistor Logic systems.
- Overvoltage tolerant inputs allowing operation in mixed-voltage environments without external components.
- Schmitt-trigger action on all inputs to enhance noise immunity and signal integrity.
Applications
- Mixed-voltage logic translation between CMOS and TTL domains.
- Signal buffering and conditioning in digital control circuits.
- Implementation of Boolean logic functions in industrial automation equipment.

Selection Notes
Select this component when TTL-level compatibility is required alongside high-speed performance. The AHCT series bridges the gap between standard AHC speed and legacy TTL input thresholds. Ensure the application environment remains within the specified 4.5 V to 5.5 V supply range to maintain correct logic threshold definitions.
Part Context
This part belongs to the 74AHCT32 family of quad 2-input OR gates manufactured by Nexperia. It shares functional characteristics with the 74AHC32 variant but differs in input threshold specifications to support TTL interfaces. The D,112 designation specifically identifies the SO14 plastic small outline package configuration.
Replacement Considerations
Nexperia datasheet lists 74AHC32D as a related variant with CMOS input levels. Cross-referencing with other manufacturers requires verifying that the substitute maintains TTL-compatible input voltage thresholds (VIH/VIL) and matches the SO14 package dimensions.
FAQ
What is the input logic level specification for the 74AHCT32?
The 74AHCT32 is designed with TTL-level input thresholds, allowing it to interface directly with standard Transistor-Transistor Logic outputs.
Does the 74AHCT32D,112 include Schmitt triggers?
Yes, all inputs on the 74AHCT32 feature Schmitt-trigger action to improve noise immunity.
