SN74AHC32N

Overview

The SN74AHC32N is a commercial-grade quadruple 2-input positive-OR gate in a 14-pin PDIP package. It operates within a supply voltage range of 2V to 5.5V, with an operating temperature range of -40°C to +125°C. The device provides ±8mA output drive at 5V and features low power consumption with a maximum ICC of 10µA. Latch-up performance exceeds 250mA per JESD 17.

Feature Summary

• Contains four independent 2-input OR gates performing the Boolean function Y = A + B
• Features balanced CMOS push-pull outputs capable of sinking and sourcing similar currents
• Includes standard CMOS inputs requiring termination to VCC or GND when unused

Applications

• Enable or disable a digital signal
• Controlling an indicator LED
• Translation between communication modules and system controllers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current orderable addendum to confirm package type and status. The SN74AHC32N designation corresponds to the PDIP package. Confirm RoHS compliance and lead finish details such as NIPDAU for the specific lot. Check for any recent documentation updates or revision history changes that may affect pinout or thermal metrics.

Selection Notes

Select this component for applications requiring multiple independent OR logic functions in a through-hole format. Ensure the design accommodates the recommended input transition rates to prevent excessive power consumption. Verify that the load capacitance does not exceed 50pF to maintain specified switching characteristics. Unused inputs must be terminated to valid logic levels.

Part Context

This part belongs to the SNx4AHC32 family of quadruple 2-input positive-OR gates manufactured by Texas Instruments. The 'SN' prefix indicates commercial grade operation, while 'AHC' denotes the advanced high-speed CMOS technology. The 'N' suffix specifically identifies the 14-pin plastic dual-in-line package (PDIP).

Replacement Considerations

Check the orderable addendum for alternative packages like SOIC (DR) or TSSOP (PW) if surface mount is required. Other variants in the family include military grade SN54AHC32.
