TIBPAL22V10-10CFN

Overview

The TIBPAL22V10-10CFN 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, supporting complex functions equivalent to 500–800 gates. The device utilizes Advanced Low-Power Schottky technology and titanium-tungsten fuses for reliability. Key electrical specifications include a maximum propagation delay of 10 ns, a maximum external feedback frequency of 71 MHz, and operation within a supply voltage range of 4.75 V to 5.25 V. It operates in a commercial temperature range of 0°C to 75°C.

Feature Summary

• Second-generation PLD architecture with variable product term distribution (8–16 terms per output).
• Programmable Output Logic Macrocells allowing individual configuration as registered or combinational, with polarity and enable control.
• TTL-level preload capability for improved testability and logical verification.
• Integrated synchronous set and asynchronous reset product terms for all registers.

Applications

• Implementation of custom LSI functions requiring up to 800 equivalent gates.
• State-machine initialization and control logic design.
• High-speed digital logic replacement for conventional TTL circuits.

Procurement Notes

Verify the specific ordering suffix 'FN' corresponds to the plastic chip carrier package variant during procurement. Confirm that the component meets the required commercial operating temperature range of 0°C to 75°C for the intended application environment. Ensure programming equipment supports the titanium-tungsten fuse technology used in this IMPACT-X series.

Selection Notes

Select the TIBPAL22V10-10CFN when designs require a maximum propagation delay of 10 ns or higher speed requirements up to 71 MHz external feedback frequency. Choose this model over slower variants if the application demands the highest performance within the IMPACT-X family. Consider the 22-input and 10-output capacity against the specific logic complexity needs, noting the variable product term allocation flexibility.

Part Context

This component belongs to the Texas Instruments IMPACT-X series of programmable array logic devices. It is functionally equivalent to other PAL-type devices from the era but distinguished by its specific timing characteristics and macrocell architecture. The 'C' suffix indicates the commercial temperature grade, while 'FN' denotes the plastic chip carrier package option.

Replacement Considerations

Functionally equivalent devices include the AMD AMPAL22V10 and AMPAL22V10AD. When substituting, verify pin compatibility and ensure the replacement device supports the required 10 ns propagation delay and 22-input/10-output configuration.
