PAL16R6-7PC

Programmable Logic Device Pld Overview

The PAL16R6-7PC is a high-speed Programmable Array Logic (PAL) device manufactured by Vantis Corporation. It belongs to the PLUS16XX family, featuring registered outputs and an AND-OR architecture with 64 programmable AND gates and 8 fixed OR gates. The component operates at a maximum clock frequency of 74 MHz with a propagation delay of 7.5 ns. It utilizes a 20-pin Plastic Dual In-line Package (PDIP). The device supports TTL logic levels and requires a nominal 5 V power supply. It provides 10 dedicated inputs and 6 registered outputs, allowing for flexible I/O configurations through bidirectional pins.

Programmable Logic Device Pld Feature Summary

• Ultra-high speed performance with 7.5 ns propagation delay and 74 MHz maximum clock frequency
• Registered output configuration providing 10 inputs and 6 outputs in a 20-pin DIP package
• 100% pin-compatible with standard PAL16R6 devices while offering enhanced speed
• Individual 3-state control available for all outputs and registers

Programmable Logic Device Pld Applications

• High-speed digital state machine implementations
• Complex glue logic replacement in legacy systems
• Register file interfaces requiring fast clock cycles
• Address decoding circuits with registered output requirements

Programmable Logic Device Pld Part Context

The PAL16R6-7PC is part of the Philips Semiconductors (now NXP) PLUS16XX series, which was later produced under the Vantis brand following industry consolidations. This specific suffix '7' denotes the high-speed variant within the PLUS16R6 family. It serves as a direct functional upgrade to the standard PAL16R6, maintaining identical pinouts and logical structure but delivering significantly improved timing characteristics suitable for faster system buses.

Programmable Logic Device Pld Replacement Considerations

The PAL16R6-7PC is functionally and pin-compatible with the standard PAL16R6. Other compatible parts include the PAL16R6-10L and PAL16R6-15L, though these offer slower speeds. When replacing, ensure the target circuit can handle the 7.5 ns propagation delay; if slower switching is acceptable, lower speed variants may be used, but higher speed variants must not exceed the system's setup/hold time constraints.
