FCT162823CTPACTE4

Overview

The FCT162823CTPACTE4 is an 18-bit bus interface register from the FCT family, manufactured by Texas Instruments. It utilizes advanced dual metal CMOS technology to provide high-speed, low-power performance suitable for replacing older ABT functions. The device features balanced output drivers with ±16mA current capability and reduced system switching noise. It operates within an extended commercial temperature range of -40°C to +85°C and requires a VCC supply of 5V ±10%. Key electrical characteristics include typical output skew less than 250ps and low input/output leakage currents not exceeding 1µA maximum.

Feature Summary

• Balanced output drivers reduce system switching noise
• High-speed operation with typical output skew under 250ps
• Low power consumption compatible with standard CMOS logic levels

Applications

• High-speed data bus interfaces in computing systems
• Telecommunications equipment requiring reliable signal latching
• Industrial automation control modules

Procurement Notes

Verify that the component matches the specific automotive-grade or industrial-grade variant requirements for your application environment. Confirm package integrity upon receipt, as moisture sensitivity may require proper handling procedures during assembly. Ensure compatibility with existing PCB footprints and soldering profiles before initiating production runs.

Selection Notes

Select this component when an 18-bit latch with balanced drive strength is required to minimize ground bounce effects. Consider its 5V operation and extended temperature range for environments where standard commercial parts may be insufficient. Evaluate the trade-off between its ±16mA drive capability and the higher drive options available in other FCT variants based on load requirements.

Part Context

This part belongs to the FCT (Fast CMOS) series, designed as a modern replacement for legacy ABT logic families. It integrates 18 bits of storage in a single package, offering significant board space savings compared to discrete solutions. The series is known for robust ESD protection and reliable performance in noisy digital environments.

Replacement Considerations

Direct substitutes include the IDT74FCT162823CTPA and generic FCT162823 equivalents. Verify pinout compatibility and electrical specifications before swapping manufacturers to ensure functional equivalence in the target circuit design.
