Overview
The SN74AHC132DBR is a quad two-input NAND gate from Texas Instruments, utilizing advanced AHC CMOS technology. It operates within a supply voltage range of 2 V to 5.5 V and features Schmitt-trigger inputs for noise filtering. The device provides low output drive currents of ±8 mA and supports propagation delays as low as 9.7 ns at 5 V. Packaged in a 14-pin TSSOP surface-mount format, it functions reliably across an industrial temperature range of -40°C to +85°C.
Feature Summary
- Integrates four independent two-input NAND gates with Schmitt trigger functionality on all inputs.
- Utilizes advanced AHC CMOS technology to achieve high-speed operation while maintaining low power consumption.
- Provides robust noise filtering capabilities through defined input thresholds inherent to the Schmitt trigger design.
Applications
- Signal conditioning and waveform shaping for noisy digital environments
- Pulse width modulation (PWM) generation circuits
- Oscillator and timing circuit implementations
Procurement Notes
Verify the specific package suffix 'DBR' corresponds to the 14-TSSOP configuration with tape-and-reel packaging. Confirm that the operating voltage requirements align with the 2 V to 5.5 V specification. Ensure thermal management strategies account for the specified -40°C to +85°C ambient temperature range during integration.
Selection Notes
Select this component when high-speed logic switching is required alongside noise immunity provided by Schmitt triggers. The AHC series offers superior speed compared to standard HC logic while maintaining compatibility with similar form factors. Consider the TSSOP package constraints for PCB layout density and thermal dissipation requirements relative to the ±8 mA output drive capability.
Part Context
This part belongs to the SN74AHC132 family of quad NAND gates. It shares functional similarities with other Schmitt trigger NAND devices but distinguishes itself through the AHC process technology, which balances speed and power efficiency better than legacy families. It serves as a direct functional replacement for older Schmitt trigger NAND ICs in modern low-voltage designs.
Replacement Considerations
Compatible alternatives include the SN74AHC132DR (SOIC-14 package) and SN74AHC132PWR (TSSOP-14 package). Verify pinout compatibility and ensure the substitute package meets the mechanical footprint requirements of the existing design.
