TIBPAL22V10ACNT

Overview

The TIBPAL22V10ACNT is a high-performance programmable array logic (PAL) circuit from the IMPACT-XE family by Texas Instruments. It features TTL-compatible inputs and outputs within a 28-pin LDCC plastic package. The device supports complex combinational and registered logic functions, offering high-speed performance suitable for digital control applications. It operates within standard industrial temperature ranges and provides reliable signal integrity for embedded systems requiring flexible logic implementation.

Feature Summary

• High-performance IMPACT-XE architecture for fast propagation delays
• TTL-compatible input and output levels ensuring broad compatibility
• Registered or combinational output configurations available
• 28-pin LDCC plastic package for surface-mount integration

Applications

• Digital logic replacement in legacy designs
• Address decoding and bus arbitration circuits
• Control logic for memory interfaces
• State machine implementation in industrial controllers

Procurement Notes

Verify the specific suffix 'CNT' against official Texas Instruments documentation to confirm package type and tape-and-reel specifications. Ensure the component matches the required speed grade and temperature range for your application environment. Cross-reference with the latest datasheet to confirm pinout compatibility and electrical characteristics before procurement.

Selection Notes

Select this component when a fixed-function PAL is insufficient but a full FPGA is unnecessary. Consider the number of available inputs, outputs, and product terms required for your logic design. Verify that the operating voltage and temperature range align with system constraints. Compare propagation delays against clock speeds to ensure timing margins are met.

Part Context

This part belongs to the Texas Instruments IMPACT-XE series of programmable logic devices. These components bridge the gap between discrete logic gates and complex programmable logic devices. They are designed for rapid prototyping and low-volume production where reprogrammability offers cost advantages over custom ASICs.

Replacement Considerations

Direct replacements include other variants within the TIBPAL22V10 series, such as different speed grades or package options like TIBPAL22V10-20MFN. Ensure functional equivalence regarding I/O count and logic capacity. Verify that any substitute maintains compatible electrical characteristics and package dimensions for existing PCB footprints.
