ITEM SPECIFICS
Brand: Fairchild Semiconductor
Model: 74LS74A PC
MPN: 74LS74A PC
Series: 74LS
Type: Dual D-Type Positive-Edge-Triggered Flip-Flop
Function: Dual D-Type Flip-Flop with Preset and Clear
Package: 14-Pin Plastic DIP
Marking: 8438A
Country/Region of Manufacture: West Germany
Quantity: 3
Condition: New old stock
DESCRIPTION
Lot of three Fairchild Semiconductor 74LS74A PC integrated circuits.
These are dual positive-edge-triggered D-type flip-flops with preset and clear functions in 14-pin plastic DIP packages. The devices are marked with the Fairchild logo, 74LS74A PC, 8438A, and W. Germany.
The chips are new old stock and show original vintage Fairchild markings. They are suitable for vintage electronics restoration, TTL logic repairs, digital logic projects, computer hardware repair, test equipment, and replacement applications requiring the 74LS74A part number.
No electrical testing has been performed. Please review all photos for exact markings, pin condition, and cosmetic condition. The lot includes the three integrated circuits shown.
COMPATIBILITY & CROSS-REFERENCE
The Fairchild 74LS74A PC is a 74LS74A-family dual D-type flip-flop with preset and clear in a 14-pin DIP for 5V TTL logic. Other 74LS74A and 74LS74AN devices share the same function and package, so they can serve as cross-references in 74LS74 sockets. It is not a drop-in for 74HC74 or 74S74 devices, which have different electrical characteristics. Use it to replace a failed 74LS74 in vintage computers, arcade boards, and TTL logic repair, and confirm the pinout against your board before installing.
Q: What does the Fairchild 74LS74A PC replace?
A: Other 74LS74A dual D flip-flops in 14-pin DIP sockets, including SN74LS74AN devices.
Q: How many flip-flops are in each chip?
A: Two independent D-type positive-edge-triggered flip-flops, each with preset and clear.
Q: Is it tested?
A: No. It is new old stock, untested and sold as shown.
DISCLAIMER
These items are new old stock. They may show minor cosmetic marks, oxidation, storage wear, or age-related appearance from long-term storage. Electrical performance has not been tested.
