74HC32N,652

Overview

The NXP USA Inc. 74HC32N,652 is a quad 2-input OR gate manufactured by Nexperia under the 74HC logic series. It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device features CMOS low power dissipation, high noise immunity, and symmetrical output impedance with balanced propagation delays. Inputs include clamp diodes for interfacing voltages exceeding VCC. Static characteristics specify input leakage current up to ±1 µA at 6.0 V and supply current up to 40 µA at +125 °C. Dynamic performance includes a maximum propagation delay of 27 ns at 4.5 V and 23 ns at 6.0 V with a 50 pF load.

• Microcontroller peripheral interfaces

Procurement Notes

Verify the specific package type against the ordering information table in the datasheet, as the 'N' suffix typically denotes a PDIP package which was removed from the latest revision (v10). Confirm the manufacturer is Nexperia, as the business formerly operated under NXP Semiconductors. Ensure compliance with RoHS3 specifications and check for any recent Product Change Notices regarding marking or assembly updates.

Selection Notes

Select this component for applications requiring standard OR logic functions with wide voltage tolerance. The 74HC series offers CMOS-level inputs suitable for modern digital systems. Consider the 74HCT32 variant if TTL-level input compatibility is required. Verify that the chosen package option matches the PCB footprint requirements, noting that older PDIP packages may have been discontinued in favor of SO or TSSOP variants.

Part Context

The 74HC32 belongs to the widely used 74HC family of high-speed CMOS logic devices. Originally developed by Philips Semiconductors and later NXP, the standard product business was transferred to Nexperia. This family provides a balance of speed, power consumption, and noise immunity, making it a staple in general-purpose digital electronics design across consumer, industrial, and computing markets.
