Product Overview

The ITT 14473557 is a high-speed TTL triple 3-input positive-AND gate housed in a standard 14-pin dual in-line package. Produced as a house-numbered component corresponding to Burroughs mainframe documentation, this microcircuit is functionally equivalent to industry-standard 74H11 and SN74H11N logic devices. It provides high-speed bipolar logic switching across three independent positive-AND gates for vintage computing maintenance and classic digital circuit repairs.

Key Features

• High-speed TTL (74H Series) logic architecture
• Triple 3-input positive-AND gate configuration
• Standard 14-pin through-hole DIP package
• Marked ITT 7628 with Burroughs part number 14473557
• Direct functional cross to 74H11 and SN74H11N logic gates

Applications

• Restoring legacy mainframe computer systems and period industrial controller boards.
• Replacing failed high-speed AND gates in vintage 7400-series TTL processing hardware.
• Breadboarding discrete logic circuits and educational computing demonstrations without modern surface-mount adapters.

Frequently Asked Questions

What is the industry-standard equivalent for this part number?

Part number 14473557 is a manufacturer cross for the 74H11 and SN74H11N triple 3-input positive-AND gate in a DIP-14 package.

What do the date and factory markings indicate?

The top line reads ITT 7628 5, indicating manufacture by ITT during the 28th week of 1976. The lower line carries the stylized Burroughs logo and part number 14473557.

Why choose this individually photographed logic IC over an untested bulk lot?

Sourcing vintage 74H series logic often means buying unpredictable bulk grabs. This chip is visually verified with readable part numbers and intact leads, priced individually so you get what you need without dead stock. Orders ship from our Idaho warehouse the same or next business day for an $8 flat rate, or free once your total passes $28.
