CPL16R8-25 - CMOS-based Programmable Logic Device (PLD)

is a CMOS-based Programmable Logic Device (PLD) designed for high-speed, low-power applications. It belongs to a legacy category of logic chips used for replacing multiple standard discrete logic gates with a single programmable integrated circuit.

Technical Specifications

This IC features the following core specifications: 

• Architecture: CMOS Programmable Logic (CPL™).
• Speed: 25ns propagation delay (indicated by the "-25" in the part number).
• Power Class: Standard power (1/2 power or standard CMOS).
• Package Type: 20-pin Plastic One-Time Programmable (OTP) package.
• Operating Temperature: Commercial grade (indicated by "C").
• Configuration: 16R8, which typically denotes 16 inputs and 8 registered (clocked) outputs. 

Device Functionality

The CPL16R8 series is designed to implement complex logic functions. Reviewers and distributors such as DERF Electronics and UTSource categorize it as a General Purpose Programmable Logic component. 

• Registers: The "R8" suffix specifically indicates that all 8 outputs are connected to internal registers, making it suitable for state machines and synchronized logic circuits.
• Technology: Built using Samsung's CMOS technology, which was favored for lower power consumption compared to older bipolar PAL devices.
