SN74F32D

Overview

The SN74F32D is a quad 2-input positive-OR gate manufactured by Texas Instruments. It belongs to the F/FAST logic series, utilizing bipolar technology for high-speed digital applications. The device operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range of 0°C to 70°C. It features push-pull outputs with a maximum low-level output current of 20mA and a maximum high-level output current of -1mA. Average propagation delay is typically between 5ns and 10ns at 5V.

Feature Summary

• Provides four independent 2-input OR logic functions in a single package
• Utilizes F/FAST bipolar technology for very high-speed switching performance
• Features push-pull outputs capable of driving standard TTL loads

Applications

• Digital signal processing circuits requiring logical OR operations
• High-speed data routing and selection logic
• General-purpose logic control systems

Procurement Notes

Verify the specific suffix (e.g., D, DR) to confirm package type and tape-and-reel configuration. Confirm RoHS compliance status as it varies by manufacturing revision. Ensure the supplier provides valid traceability documentation for the Texas Instruments part number. Check for any recent Product Change Notifications that may affect pinout or electrical characteristics.

Selection Notes

Select this component when high-speed OR logic is required in a standard 14-pin SOIC package. Compare against SN74LS32 if lower speed but higher noise immunity is acceptable. Consider SN74HC32 for lower power consumption requirements. Verify that the 20mA drive capability meets the load requirements of the downstream circuitry without exceeding absolute maximum ratings.

Part Context

This component is part of the SN74F family of high-speed logic devices. It serves as a direct functional replacement for older 74S32 equivalents with improved speed. The 'D' suffix indicates a 14-pin Small Outline Integrated Circuit (SOIC) package suitable for surface-mount assembly. It is widely used in industrial and consumer electronics where fast response times are critical.
