SN74AHCT32DBR

Overview

The SN74AHCT32DBR is a quadruple 2-input positive-OR gate manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features low input current due to CMOS construction. The device utilizes a 14-pin SOIC package and supports surface-mount installation. It functions across an extended temperature range from -40°C to +85°C, ensuring reliable performance in industrial applications.

Feature Summary

• Contains four independent 2-input OR logic gates within a single integrated circuit
• Compatible with standard CMOS outputs while accepting TTL-level inputs for mixed-signal interfacing
• Provides high noise immunity and low power consumption characteristics typical of HCT logic families

Applications

• General-purpose digital logic signal processing
• Data acquisition systems requiring logical OR operations
• Industrial control circuits operating at 5V logic levels

Procurement Notes

Verify the specific suffix 'DR' corresponds to the standard 14-SOIC package variant when sourcing. Confirm RoHS compliance status as manufacturing processes may update component specifications over time. Ensure the supplier provides official datasheets matching the exact part number to avoid confusion with similar HCT series devices.

Selection Notes

Select this component when designing 5V logic circuits requiring multiple OR gates in a compact surface-mount form factor. It serves as a suitable replacement for legacy 74HCT32 equivalents in modern PCB layouts. Consider thermal management requirements if operating near the upper temperature limit of the specified range.
