Product Overview

Philips Semiconductor 74HCT32N is a high-speed Si-gate CMOS integrated circuit containing four independent 2-input positive-OR gates in a 14-pin dual in-line package. Engineered with TTL-compatible input switching thresholds, this device provides pin and logic compatibility with classic 74LS series bipolar circuits while delivering low CMOS power dissipation. It operates across a nominal 4.5V to 5.5V supply range and features standard push-pull outputs capable of directly driving TTL, NMOS, and CMOS inputs.

Key Features

• Four independent 2-input positive-OR logic gates
• TTL-compatible input voltage switching thresholds for direct drop-in replacement of 74LS32 gates
• Operating supply voltage range of 4.5V to 5.5V
• Standard 14-lead plastic dual in-line package (DIP-14)
• Push-pull outputs interface directly with TTL, NMOS, and CMOS logic families

Applications

• Replacing damaged logic gates on vintage computer mainboards and industrial controller boards
• Assembling digital logic prototypes and hobbyist breadboard computing sub-circuits
• Interfacing 5V TTL control stages with modern CMOS logic architectures

Frequently Asked Questions

Can the 74HCT32N replace a standard 74LS32 logic chip?

Yes. The 74HCT series features TTL-compatible input voltage levels and identical pin assignments, allowing direct drop-in substitution for 74LS32 bipolar OR gates in standard 5V circuits.

What supply voltage does this IC require?

The 74HCT32 operates within a standard VCC supply range of 4.5V to 5.5V.

Why buy a single genuine Philips 74HCT32N instead of a bulk lot?

For bench repairs, legacy restoration, or breadboard development, purchasing an individually cataloged, verified-marking component provides the exact part needed without excess inventory overhead. Shipping is $8 flat rate, free once the order passes $28, and orders leave the Idaho warehouse the same or next business day.

When you just need four honest OR gates to settle an old logic line, a genuine through-hole DIP-14 chip from the classic semiconductor era gets the job done cleanly.
