PAL22V10Z-25CJTL

Overview

The TIBPAL22V10Z-25CJTL is a high-performance Impact E programmable array logic circuit from Texas Instruments. It features 22 inputs and 10 outputs with an average of 12 product terms per output. The device supports variable product term distribution for complex functions. Each output is user-programmable for registered or combinational operation, polarity, and output enable control. The -25CJTL suffix indicates a maximum propagation delay of 25 ns.

Feature Summary

• Second-generation PLD architecture with increased logic capacity
• Variable product term distribution allows implementation of complex functions
• TTL-level preload capability improves testability
• Extra terms provide logical synchronous set and asynchronous reset

Applications

• General-purpose digital logic implementation
• Address decoding and bus switching
• State machine design
• Interface logic conversion

Procurement Notes

Verify the specific suffix 'Z' against official Texas Instruments documentation to confirm if it denotes a specific package variant or environmental rating distinct from standard commercial grades. Ensure the source document explicitly lists this exact part number, as distributors may list generic family members like TIBPAL22V10AC or TIBPAL22V10AM. Confirm pinout compatibility with legacy designs referencing AMD AMPAL22V10 equivalents.

Selection Notes

Select this component when a 25 ns speed grade is required for PAL-based logic applications. The device offers 22 inputs and 10 outputs, suitable for moderately complex logic functions. Consider the registered or combinational output configuration options based on timing requirements. Verify that the TTL input levels match the system voltage standards. Compare against the functionally equivalent AMD AMPAL22V10AD if sourcing from alternative suppliers.

Part Context

This part belongs to the Texas Instruments Impact E series of simple programmable logic devices (SPLDs). These circuits utilize Ti-W fuses for programming, ensuring high reliability and yield. The family includes variants with different speed grades such as 25 ns, 30 ns, and 35 ns. The technology is designed for applications requiring fast programming and dependable quality, supporting both plastic and ceramic package options.

Replacement Considerations

The TIBPAL22V10Z-25CJTL is functionally equivalent to the AMD AMPAL22V10 and AMPAL22V10AD. When substituting, verify that the replacement device maintains the same 25 ns maximum propagation delay and pinout configuration. Ensure the substitute supports the same TTL input levels and output drive capabilities.
