PAL16R4BCJ

Programmable Logic Device Pld Overview

The PAL16R4BCJ is a high-performance Programmable Array Logic (PAL) device manufactured by Vantis Corporation. It belongs to the OT PLD family, featuring a TTL-compatible architecture with a maximum propagation delay of 25 ns and a maximum clock frequency of 25 MHz. The component utilizes a 20-pin Plastic Dual In-Line Package (PDIP). It provides 12 dedicated inputs and 8 registered outputs, organized into 64 product terms. The device operates at a nominal supply voltage of 5 V and is rated for commercial temperature ranges.

Programmable Logic Device Pld Feature Summary

• TTL-compatible PAL architecture with 25 ns propagation delay
• 12 dedicated inputs and 8 registered outputs in a PDIP-20 package
• 64 product terms for complex logic implementation
• Registered output function for synchronous design applications

Programmable Logic Device Pld Applications

• Synchronous state machine implementations
• Address decoding logic in computer systems
• Bus control interface circuits
• General-purpose digital logic replacement

Programmable Logic Device Pld Procurement Notes

Verify the specific suffix 'CJ' against manufacturer documentation to confirm package material and temperature grade. Ensure compatibility with existing 5V logic levels. Check for RoHS compliance status as older PAL devices may not meet current environmental standards. Confirm lead availability through authorized distributors due to potential end-of-life status.

Programmable Logic Device Pld Selection Notes

Select this component when registered outputs are required for timing synchronization. Compare propagation delays against system clock requirements; the 25 ns delay suits moderate-speed applications. Verify input count sufficiency for the target logic complexity. Consider alternative packages if surface-mount technology is preferred over through-hole DIP.

Programmable Logic Device Pld Part Context

This part is part of the PAL16R4 series, a widely used line of simple programmable logic devices. Vantis Corporation produced these components following the acquisition of earlier PAL technologies. The device serves as a drop-in replacement for legacy PAL16R4 designs in industrial and consumer electronics.

Programmable Logic Device Pld Replacement Considerations

Direct pin-compatible replacements include the Lattice GAL16V8B or AMD PAL16R4 variants. Verify electrical characteristics such as output drive strength and input thresholds before substitution. Ensure programming tool compatibility for re-flashing if field-programmable capabilities are needed.
