Description and Introduction

Programmable Array Logic 24-Pin Medium PAL Series -7,-5,and -4 The **PAL20R4-7JC** is a programmable array logic (PAL) device designed for digital logic applications. As part of the PAL family, it offers a flexible solution for implementing custom combinational and sequential logic circuits. The "20R4" designation indicates that the device features 20 inputs and 4 registered outputs, making it suitable for state machine designs and other timing-critical applications.  

Built with bipolar technology, the PAL20R4-7JC operates at a propagation delay of **7 ns**, ensuring high-speed performance for demanding logic operations. Its programmable AND array and fixed OR array structure allow designers to create tailored logic functions while maintaining efficiency. The device is housed in a **PLCC (Plastic Leaded Chip Carrier)** package, providing reliable mounting options for PCB integration.  

Key features include **electrically erasable (EE) programmability**, enabling easy modifications during development. The PAL20R4-7JC is commonly used in industrial control systems, telecommunications, and embedded computing, where fast, deterministic logic is essential.  

For engineers working with legacy systems or seeking a proven programmable logic solution, the PAL20R4-7JC remains a viable choice due to its balance of speed, flexibility, and reliability. Proper handling and programming tools are required to maximize its capabilities in circuit design.

Application Scenarios & Design Considerations

Alternative Part Number

  • GAL20V8B-15LJ --: Generic array logic device in a 24-pin PLCC package that can emulate the PAL20R4 architecture, offering a direct functional replacement with similar speed grade.
  • ATF20V8B-15JC --: Electrically erasable PLD compatible with 20R4-type PAL designs, same 24-pin PLCC footprint and comparable propagation delay, suitable as a drop-in substitute.
  • PAL20L8BCNS --: Classic bipolar PAL in the 20L8 family with a superset of the 20R4 logic capability, widely available and pin-compatible in DIP form for legacy board rework.
  • TIBPAL20R4-7JC --: TI second-source PAL20R4 device with matching 7 ns speed grade and JC package, functionally equivalent replacement.
  • PAL20R4-10JC --: Same PAL20R4 family and JC package but slower 10 ns grade; usable if timing margin allows.
  • GAL20V8B-7LJ --: Generic array logic device that can emulate the PAL20R4 logic with 7 ns speed in a PLCC package, offering a reprogrammable alternative.
