TIBPAL22VP10-20CFN

Overview

The TIBPAL22VP10-20CFN is a high-performance Impact-XE Programmable Array Logic (PAL) circuit manufactured by Texas Instruments. It features a PAL-type architecture with TTL logic compatibility, housed in a 28-pin LDCC plastic package. The device supports up to 22 input lines and 10 registered output lines, providing complex logic implementation capabilities. Designed for industrial temperature ranges, it operates at a maximum clock frequency of 20 MHz with a propagation delay of 20 ns. The component utilizes a 5 V nominal supply voltage and includes registered outputs for synchronous application support.

Feature Summary

• Impact-XE PAL architecture with 22 inputs and 10 registered outputs
• TTL-compatible logic levels for standard digital interfacing
• 20 ns maximum propagation delay supporting 20 MHz operation
• 28-pin LDCC plastic package suitable for surface mount applications

Applications

• Synchronous state machine implementations
• Address decoding logic in embedded systems
• Data bus buffering and protocol conversion
• Timing control circuits requiring registered outputs

Part Context

This component belongs to the Texas Instruments Impact-XE family of simple PLDs. These devices are designed to replace fixed-function logic gates with reconfigurable solutions. The 'V' suffix indicates registered outputs, while 'FN' denotes the specific 28-pin LDCC package variant. This family offers higher performance compared to earlier Impact series parts.

Replacement Considerations

Direct pin-to-pin replacements within the same package require verifying logic function equivalence. Other variants in the TIBPAL22VP10 series may offer different speed grades or temperature ranges. Ensure that any substitute maintains the 22-input/10-output configuration and registered output capability.
