74AHCT132D,112

Overview

The Nexperia 74AHCT132D,112 is a quad 2-input NAND gate with Schmitt-trigger inputs. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL input levels. The device provides high noise immunity and overvoltage tolerant inputs up to 5.5 V. It is housed in an SO14 plastic small outline package (SOT108-1) with a body width of 3.9 mm. Propagation delay is specified at 1.0 ns to 10.0 ns depending on load capacitance. Operating temperature ranges from -40 °C to +125 °C.

Selection Notes

Select this component when TTL-compatible logic levels are required alongside Schmitt-trigger functionality. The AHCT series ensures compatibility with standard TTL outputs while maintaining CMOS low power dissipation characteristics. Ensure the application environment stays within the specified 4.5 V to 5.5 V supply voltage range for proper operation.

Part Context

This part belongs to the Nexperia 74AHC(A)HCT logic family, which combines the high-speed performance of AHC technology with the pinout and input compatibility of HCT devices. The 74AHCT132 variant specifically targets applications requiring robust noise immunity and clean signal transitions in mixed-voltage environments.

Replacement Considerations

Check for equivalent parts such as the 74HC132 if CMOS input levels are acceptable instead of TTL. Verify package compatibility (SO14/SOT108-1) and ensure thermal derating requirements are met for the target operating temperature.
