TIBPAL20R8-10CNT

Overview

The TIBPAL20R8-10CNT is a high-performance Impact-X PAL circuit manufactured by Texas Instruments. It features 12 inputs and 8 registered outputs with 3-state buffers, housed in a 24-pin plastic DIP package. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports an operating temperature range of 0°C to 75°C. Key electrical specifications include a maximum propagation delay of 10 ns, a typical supply current of 210 mA, and a maximum clock frequency of 71.4 MHz without feedback.

Feature Summary

• High-speed performance with 10 ns maximum propagation delay and 71.4 MHz max clock frequency
• Registered output architecture with preload capability for simplified testing
• Power-up clear feature sets all register outputs to low level upon initialization
• Security fuse implementation prevents unauthorized duplication of the design

Applications

• Complex state machine implementations requiring registered outputs
• High-speed counter designs utilizing internal feedback configurations
• System logic replacement for conventional TTL circuits
• Custom function design requiring compact board space reduction

Procurement Notes

Verify component authenticity through authorized distributors or TI direct channels. Confirm package integrity and pin alignment prior to installation. Ensure programming equipment compatibility with TI Impact-X fuse structures. Review datasheet SRPS008A for specific handling and storage requirements to maintain device reliability.

Selection Notes

Select this model when eight registered outputs with 3-state control are required. The 10C suffix indicates commercial temperature range operation (0°C to 75°C). Verify input count matches the 12-input constraint. Consider the TIBPAL20L8 variant if registered outputs are not needed, as it offers six I/O ports instead.

Part Context

This component belongs to the TIBPAL20xx-10C series, which includes variants like TIBPAL20L8-10C, TIBPAL20R4-10C, and TIBPAL20R6-10C. All share the same high-performance Impact-X architecture and 10 ns speed grade but differ in output registration and I/O port configurations.
