PAL16R8CN

Programmable Logic Device Pld Overview

The PAL16R8CN is a Programmable Array Logic (PAL) device belonging to the PAL Series 24. It features an architecture with 8 inputs and 8 registered outputs, providing 64 product terms for logic implementation. The component operates at a maximum clock frequency of 25 MHz with a propagation delay of 25 ns. It utilizes TTL logic levels and requires a 5 V power supply. The device is housed in a 20-pin Plastic Quad Flat Pack (PQCC) package, specifically designated as J-20, suitable for surface-mount applications requiring high-speed digital logic processing.

Programmable Logic Device Pld Feature Summary

• PAL-Type architecture with 8 inputs and 8 registered outputs
• Maximum operating frequency of 25 MHz
• TTL logic compatibility with 5 V supply voltage
• 20-pin PQCC (J-20) surface mount package

Programmable Logic Device Pld Applications

• High-speed digital logic control circuits
• State machine implementations
• Address decoding networks

Programmable Logic Device Pld Procurement Notes

Verify RoHS compliance status, as specific listings indicate non-compliance. Confirm the manufacturer origin, noting that Vantis Corporation was acquired by National Semiconductor, which is now part of Texas Instruments. Ensure the ordering suffix corresponds to the correct package variant and speed grade before procurement.

Programmable Logic Device Pld Selection Notes

Select this component when a registered output PAL with 8 I/O lines is required. The 25 ns delay suits moderate-speed digital designs. Compare against the PAL16R8DPC or PAL16R8ACNL for equivalent performance in different packaging options such as DIP or PLCC if surface mount is not feasible.

Programmable Logic Device Pld Part Context

The PAL16R8CN is part of the broader PAL16R8 family, which includes variants like PAL16L8 and PAL16R6. These devices are standard high-speed PAL circuits originally developed by National Semiconductor and later produced under the Vantis brand following industry consolidations. They represent a transition from fixed-function logic to user-programmable solutions.

Programmable Logic Device Pld Replacement Considerations

Direct replacements include the PAL16R8ACNL and PAL16R8DPC. Verify pinout compatibility, particularly regarding ground pin placement in PLCC packages, to ensure seamless integration into existing PCB layouts without redesign.
