74FCT162245CTPACT

Overview

The Texas Instruments 74FCT162245CTPACT is a high-speed, low-power CMOS bus transceiver belonging to the 74FCT logic family. It integrates two independent bidirectional data paths, each handling eight bits for a total of sixteen channels. The device operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible input and output levels. It provides balanced output drive currents of 24 mA for both sourcing and sinking. The component is housed in a 48-pin TSSOP package with a maximum propagation delay of 3.5 ns at a 50 pF load.

Feature Summary

• Dual 8-bit bidirectional architecture providing 16-bit data transfer capability
• TTL-compatible input and output logic levels for system integration
• Balanced output drivers ensuring symmetric signal integrity

Applications

• High-speed memory bus interfaces
• Microprocessor-to-peripheral communication links
• Bidirectional data buffering in computing systems

Procurement Notes

Verify the specific suffix 'CTPACT' against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Ensure the procurement source provides original manufacturer documentation rather than generic distributor descriptions. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process before finalizing orders.

Selection Notes

Select this component when a 16-bit bidirectional interface is required with TTL-level compatibility. The balanced 24 mA drive strength supports moderate capacitive loads typical in standard digital systems. Consider the 48-pin TSSOP package constraints regarding board space and thermal dissipation during the design phase.

Part Context

This part belongs to the industry-standard 74FCT series, designed as a Fast CMOS alternative to older transistor-transistor logic families. It offers improved switching speeds while maintaining power consumption characteristics suitable for general-purpose digital applications. The device serves as a bridge between different logic domains requiring bidirectional data flow.

Replacement Considerations

Cross-reference with IDT74FCT162245CTPAG or PI74FCT162245T for equivalent functionality from other manufacturers. Verify that substitute parts maintain the same 48-pin TSSOP footprint and 4.5V-5.5V operating voltage range.
