TICPAL22V10Z-25CNT

Overview

The TICPAL22V10Z-25CNT is a 24-pin CMOS programmable array logic circuit featuring 12 dedicated inputs and 10 user-definable outputs. It operates at a nominal 5 V supply with an industrial temperature range of -40°C to 85°C. In turbo mode, the maximum propagation delay from input to output is 25 ns, while clock-to-Q delay reaches 15 ns max. The device utilizes UV-erasable EPROM technology for reprogrammability.

Feature Summary

• Variable product term distribution allocates up to 16 terms per output for complex functions
• User-programmable macrocells support registered or combinational operation with polarity control
• Virtually zero standby power consumption in static conditions
• Programmable design security bit prevents unauthorized copying of stored logic

Applications

• Low-power digital logic replacement for high-performance TTL PLDs
• Custom LSI function development requiring flexible I/O configurations
• Systems requiring synchronous set and asynchronous reset capabilities
• Applications demanding full logical verification via output register preload

Procurement Notes

Verify that the specific suffix CNT corresponds to the plastic dual-in-line package variant within the TICPAL22V10Z series. Confirm the operating temperature grade matches the -40°C to 85°C specification required for the application environment. Ensure programming equipment supports the floating-gate avalanche injection technique and UV erasure requirements specified in the datasheet.

Selection Notes

Select this component when designing systems that require low static power dissipation combined with high-speed logic performance. The variable product term architecture allows for more complex implementations compared to fixed-term PALs. Consider the UV window requirement for erasure if field reprogramming is necessary, or utilize the design security feature for production protection.

Part Context

This device belongs to the EPIC (Enhanced Processed Implanted CMOS) family of programmable logic devices manufactured by Texas Instruments. It serves as a CMOS-compatible alternative to bipolar PLD architectures, offering similar pinouts and functionality with significantly reduced power consumption. The architecture supports direct interface to CMOS memory and ASIC devices without external pull-up resistors.

Replacement Considerations

Functionally equivalent to AMD AMPAL22V10 and AMPAL22V10AD devices. Verify pinout compatibility and electrical characteristics against existing designs when substituting. Note that the EPIC process offers lower standby power but requires UV exposure for erasure, unlike electrically erasable alternatives.
