SN74AHC32NSR

Overview

The SN74AHC32NSR is a commercial-grade quadruple 2-input positive-OR gate from the Texas Instruments SNx4AHC32 family. It operates within a supply voltage range of 2V to 5.5V and supports an operating temperature range of -40°C to +125°C. The device provides ±8mA output drive at 5V, with a maximum ICC of 10µA. Switching characteristics include a propagation delay of 5.3ns (typical) at 5V with 50pF load. It utilizes standard CMOS inputs and balanced push-pull outputs in a 14-pin NS package.

Feature Summary

• Performs Boolean OR logic functions using four independent gates
• Features balanced CMOS push-pull outputs for similar sourcing and sinking currents
• Includes negative clamping diodes on inputs and dual clamping diodes on outputs
• Standard CMOS inputs require termination to prevent undefined operational states

Applications

• Enable or disable digital signals
• Controlling indicator LEDs
• Translation between communication modules and system controllers

Procurement Notes

Verify that the specific ordering suffix matches the required package type and environmental rating. Confirm RoHS compliance status and lead finish specifications against current manufacturer documentation. Ensure the component meets the intended operating temperature range requirements for the target application environment before finalizing procurement decisions.

Selection Notes

Select this component when a wide supply voltage range from 2V to 5.5V is required for OR logic operations. Consider the -40°C to +125°C commercial temperature rating for industrial environments. Evaluate the 5.3ns typical propagation delay and 8mA drive capability against system timing and load requirements. Verify compatibility with standard CMOS input levels and ensure unused inputs are properly terminated.

Part Context

This part belongs to the SNx4AHC32 series of quadruple 2-input positive-OR gates manufactured by Texas Instruments. The 'SN' prefix indicates a commercial-grade device, while 'AHC' denotes the advanced high-speed CMOS technology. The 'NS' suffix specifies the 14-pin Small Outline Package (SOP). This series offers low power consumption and robust latch-up performance exceeding 250mA per JESD 17 standards.

Replacement Considerations

Direct replacements within the same family include SN74AHC32DR and SN74AHC32DBR. Alternative packages such as TSSOP (PW) or SSOP (DB) may be considered if pinout compatibility allows. Military-grade variants like SN54AHC32 offer extended temperature ranges but differ in qualification standards.
