SN74AHC132RGYR

Overview

The SN74AHC132RGYR is a quad Schmitt-trigger NAND gate from Texas Instruments' AHC logic family, housed in a VQFN-14 package. It operates within a supply voltage range of 2V to 5.5V and supports an operating temperature range of -40°C to +85°C. The device features low static power consumption and high noise immunity characteristic of CMOS technology. Propagation delay is typically 6ns at 5V. Outputs provide 8mA drive capability for both high and low states, ensuring robust signal integrity in digital logic applications requiring hysteresis.

Feature Summary

• Integrates four independent 2-input NAND gates with Schmitt-trigger inputs for noise filtering
• Operates across a wide 2V to 5.5V supply voltage range compatible with various logic families
• Provides high noise immunity and clean transitions through defined input thresholds
• Utilizes low-power CMOS technology suitable for battery-operated systems

Applications

• Signal conditioning for noisy digital environments
• Wave shaping of slow-rise or slow-fall time signals
• Debouncing mechanical switches in digital interfaces
• Oscillator circuits requiring precise threshold control

Procurement Notes

Verify the specific suffix RGYR corresponds to the VQFN-14 package variant when sourcing. Confirm RoHS compliance status via the manufacturer's latest documentation. Ensure ESD handling protocols are followed due to CMOS sensitivity. Cross-reference the datasheet revision date to ensure alignment with current design specifications. Validate thermal performance requirements against the intended operating environment before final procurement.

Selection Notes

Select this component when Schmitt-trigger action is required for NAND logic functions. The AHC series offers faster speeds than standard HC devices while maintaining 5V compatibility. Consider the VQFN-14 package for space-constrained PCB layouts. Verify that the 2V minimum supply voltage meets the lowest system rail requirement. Compare propagation delays against timing constraints if high-speed operation is critical.

Part Context

This part belongs to the SN74AHC132 family of quad 2-input NAND gates with Schmitt triggers. The RGYR suffix denotes the specific VQFN-14 surface-mount package configuration. It is part of Texas Instruments' broader AHC logic portfolio designed for high-speed, low-power applications. The device serves as a direct replacement for older Schottky TTL equivalents in modern CMOS designs.
