TIBPAL22V10-7CFN

Overview

The TIBPAL22V10-7CFN is a high-performance IMPACT-X programmable array logic circuit manufactured by Texas Instruments. It features up to 22 inputs and 10 outputs with an average of 12 product terms per output. The device operates at a maximum propagation delay of 7.5 ns and supports external feedback frequencies up to 80 MHz. Each output macrocell is user-programmable for registered or combinational operation, polarity, and output enable control. It utilizes titanium-tungsten fuses for programming and includes TTL-level preload capabilities.

Feature Summary

• Second-generation PLD architecture with Advanced Low-Power Schottky technology
• Variable product term distribution (8 to 16 terms per output)
• Synchronous set and asynchronous reset capability for all registers
• Power-up clear function for registered outputs

Applications

• Custom LSI functions requiring 500 to 800 equivalent gates
• State-machine initialization and control logic
• High-speed digital logic replacement for conventional TTL circuits

Procurement Notes

Verify the device status as LIFEBUY, indicating discontinuation with a lifetime-buy period available. Confirm the package type FN corresponds to the 28-pin plastic J-leaded chip carrier. Ensure compliance with RoHS standards if applicable to the specific production lot. Check for lead finish specifications such as CU SNPB in ordering documentation.

Selection Notes

Select this component when designing systems requiring up to 22 dedicated inputs and 10 I/O lines. The 7C speed grade provides a maximum propagation delay of 7.5 ns. Consider thermal management requirements if operating at high frequencies with multiple switching outputs. Verify that the 0°C to 75°C operating temperature range meets system environmental constraints.

Part Context

This part belongs to the TIBPAL22V10 series of IMPACT-X programmable array logic devices. It is functionally equivalent to AMD AMPAL22V10 variants. The device represents a second-generation PLD offering increased logic power compared to earlier PAL architectures through variable product term distribution.

Replacement Considerations

Functionally equivalent parts include AMD AMPAL22V10 and AMPAL22V10AD. Verify pin compatibility and electrical characteristics before substitution. Other TI PAL variants may share architectural similarities but differ in speed grades or package options.
