The PAL16L8H-15PC is a Programmable Array Logic (PAL) device, manufactured by Rochester Electronics. It is a widely used logic device that provides a flexible and cost-effective solution for implementing custom digital circuits. The '16L8' designation indicates a specific architecture with 16 inputs and 8 outputs, where the 'L' denotes active-low outputs. The '-15' signifies a propagation delay of 15 nanoseconds, representing the device's speed. The 'PC' likely refers to the package type, most probably a plastic DIP (Dual In-line Package).

Applications

• Address decoders
• Chip Select logic
• State machines
• Combinatorial logic functions
• Interface controllers

Features

• Programmable AND array
• Fixed OR array
• 16 inputs
• 8 active-low outputs
• 15ns propagation delay
• DIP package

Benefits

• Reduces component count compared to discrete logic gates.
• Simplifies circuit design and debugging.
• Allows for easy modification of logic functions through reprogramming.
• Provides a cost-effective solution for implementing custom logic.

The PAL16L8H-15PC is programmed using a PAL programmer, which blows fuses within the AND array to define the desired logic functions. It's important to use the correct programming algorithm and verify the programmed logic after programming. Due to its non-volatile nature, the programmed logic is retained even when power is removed. For detailed information on programming, timing characteristics, and pinout information, consult the device datasheet available from Rochester Electronics or other reliable sources. This device is often employed in legacy systems and can be difficult to replace with newer technology without significant redesign.
