SN74AHCT132DBR

Overview

The SN74AHCT132DBR is a quadruple positive-NAND gate with Schmitt-trigger inputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features an output drive capability of ±8 mA at 5 V. The device exhibits low power consumption with a maximum ICC of 10 μA. Propagation delay is specified at 6.5 ns. It is housed in a 14-SOIC surface-mount package and supports operation from very slow input transitions.

Feature Summary

• Quadruple positive-NAND logic function
• Schmitt-trigger inputs for noise immunity
• High output drive current of ±8 mA
• Low static power consumption

Applications

• Signal conditioning for noisy environments
• Pulse width modulation circuits
• Frequency division circuits
• Timing and control logic

Procurement Notes

Verify the specific suffix 'DBR' corresponds to the 14-SOIC tape-and-reel packaging configuration. Confirm that the operating voltage requirements strictly adhere to the 4.5 V to 5.5 V range, as this is an HCT variant compatible with 5 V CMOS systems. Ensure thermal management aligns with the SOIC-14 package thermal characteristics during high-frequency switching operations.

Selection Notes

Select this component when 5 V logic compatibility is required alongside Schmitt-trigger hysteresis for signal integrity. The AHCT series ensures TTL-compatible input thresholds while maintaining CMOS output levels. Consider the ±8 mA drive strength for moderate load driving needs without external buffers. Verify package availability matches the assembly line requirements for SOIC-14 components.

Part Context

This part belongs to the SN74AHCT132 family of quadruple NAND gates with Schmitt triggers. It is designed for 5 V applications, bridging TTL and CMOS logic families. The device provides robust noise rejection due to its input structure, making it suitable for industrial and consumer electronics where signal stability is critical across varying temperature conditions.

Replacement Considerations

SN74AHCT132DR (Texas Instruments) offers identical electrical specifications in a standard SOIC-14 reel format. SN74AHCT132D (Texas Instruments) provides the same die in a tube package rather than tape-and-reel. Cross-reference pinouts and electrical parameters to ensure functional equivalence before substitution.
