TICPAL22V10Z-25CFN

Overview

The TICPAL22V10Z-25CFN 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 0°C to 75°C. Propagation delays are specified as 25 ns maximum in Turbo mode and 35 ns maximum in Zero-Power mode for input-to-output transitions. Clock-to-Q delays reach 15 ns in Turbo mode.

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
• UV-erasable floating-gate technology enables reconfigurable logic and design security bits
• Turbo and Zero-Power modes allow optimization between speed and standby power consumption

Applications

• Low-power digital logic replacement for legacy TTL circuits
• Custom state machine implementation with synchronous set and asynchronous reset capabilities
• Interface bridging between CMOS and TTL logic families
• Prototyping of medium-complexity LSI functions requiring reprogrammability

Procurement Notes

Verify the device package matches the Plastic Chip Carrier (FN) designation, as the suffix indicates specific physical form factors. Confirm that the -25C speed grade aligns with system timing requirements for the intended operating temperature range. Ensure programming equipment supports UV erasure and floating-gate avalanche injection techniques required for this EPIC architecture.

Selection Notes

Select this component when low standby power is critical alongside moderate switching speeds. The variable product term architecture offers greater flexibility than fixed-term PALs for complex decoding. Consider the -30I variant if extended temperature ranges are necessary. Verify that the application can accommodate UV exposure for erasure if field reprogramming is required.

Part Context

This device belongs to Texas Instruments' EPIC family of CMOS PLDs, combining enhanced processed implanted CMOS processes with UV-erasable memory. It serves as a direct functional substitute for older bipolar PAL devices while offering significantly reduced power dissipation. The architecture supports high-density logic implementation within a compact 24-pin footprint.

Replacement Considerations

Functionally equivalent devices include the AMD AMPAL22V10 series. When substituting, verify pinout compatibility and ensure the replacement supports the required voltage levels and signal integrity characteristics. Note that bipolar predecessors may have different switching behaviors and power profiles compared to this CMOS implementation.
