PAL16R6-7JC

Overview

The PAL16R6-7JC is a high-speed Programmable Array Logic (PAL) device manufactured by Vantis Corporation. It belongs to the PLUS16XX family, featuring an ultra-high-speed performance with a maximum propagation delay of 7.5 ns and a maximum clock frequency of 74 MHz. The device utilizes a TTL-compatible architecture housed in a 20-pin Plastic Quad Chip Carrier (PQCC/JC) package. It provides 10 input lines and 6 registered output lines, supported by 64 programmable AND gates and fixed OR gates. The component operates at a nominal supply voltage of 5 V and includes individual three-state control for outputs and registers.

Feature Summary

• Ultra-high-speed operation with 7.5 ns propagation delay and 74 MHz max clock frequency
• 10 inputs and 6 registered outputs with individual three-state control
• 64 programmable AND gates and 8 fixed OR gates architecture
• Compatible with standard PAL logic families including 16L8, 16R8, 16R6, and 16R4

Applications

• High-speed digital logic replacement
• State machine implementation
• Address decoding circuits
• Timing control logic

Procurement Notes

Verify the specific suffix 'JC' corresponds to the Plastic Quad Chip Carrier package variant when sourcing. Confirm RoHS compliance status as historical Vantis PAL devices may not meet current environmental standards. Ensure programming equipment supports the PLUS16XX family architecture for successful configuration.

Selection Notes

Select this component when registered outputs with three-state capability are required alongside high-speed performance. The 10-input/6-output ratio suits applications needing moderate I/O density. Compare against the PAL16R8-7 series if additional output lines are necessary, noting that the R6 variant offers fewer outputs but maintains identical speed characteristics.

Part Context

This part is part of the PLUS16XX series produced by Vantis, formerly AMD's programmable logic division. The PLUS16XX family was designed as a drop-in replacement for older Series 20 PAL devices, offering improved speed while maintaining pin compatibility. The JC suffix specifically denotes the quad flat no-lead or chip carrier package style used for surface-mount applications.

Replacement Considerations

Direct functional replacements include the PLUS16R8-7JC for increased output capacity. Older generation PAL16R6 devices may serve as pin-compatible alternatives if speed requirements are relaxed. Verify package footprint compatibility before substituting with other manufacturers' PLDs.
