74AHCT132PW,118

Overview

The Nexperia 74AHCT132PW,118 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 accepts TTL input levels. The device features overvoltage tolerant inputs up to 5.5 V, enabling use in mixed-voltage environments. Propagation delay ranges from 1.0 ns to 10.0 ns depending on load capacitance. It is housed in a TSSOP14 package (SOT402-1) and supports an ambient temperature range of -40 °C to +125 °C.

Feature Summary

• Quad 2-input NAND logic function with Schmitt-trigger action for noise immunity
• Overvoltage tolerant inputs allowing operation in mixed voltage systems
• CMOS low power dissipation characteristics
• ESD protection compliant with ANSI/ESDA/JEDEC standards

Applications

• Signal translation between TTL and CMOS logic domains
• Relaxation oscillator circuits utilizing feedback components
• Digital signal conditioning requiring hysteresis
• General-purpose logic processing in mixed-voltage embedded systems

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the application environment remains within the specified 4.5 V to 5.5 V supply voltage limits. Ensure thermal management accounts for total power dissipation derating above 81 °C for the TSSOP14 package. Validate compatibility with target system operating temperatures ranging from -40 °C to +125 °C before finalizing procurement.

Selection Notes

Select this component when TTL-compatible inputs are required alongside Schmitt-trigger noise immunity. The 74AHCT series specifically targets 5 V logic systems, distinguishing it from the broader 2.0 V to 5.5 V range of the 74AHC variant. Consider the TSSOP14 package for space-constrained surface-mount designs requiring a 4.4 mm body width.

Part Context

This part belongs to the Nexperia 74AHC/AHCT family of high-speed CMOS logic devices. The 'AHCT' designation indicates compatibility with TTL input voltage levels while maintaining CMOS output drive capabilities. The 'PW' suffix identifies the plastic thin shrink small outline package (TSSOP). This family provides balanced propagation delays and robust performance across industrial temperature ranges.

Replacement Considerations

Direct pin-to-pin replacements within the same package must maintain the 74AHCT132 logic function. Verify that alternative manufacturers offer equivalent TTL input thresholds and Schmitt-trigger characteristics. Ensure the substitute device supports the required 4.5 V to 5.5 V operating voltage and TSSOP14 footprint.
