74FCT162244CTPAG

Overview

The IDT74FCT162244CTPAG is a dual bus transceiver within the 74FCT logic series, packaged in a 48-pin TSSOP. It integrates two independent 8-bit transceivers, providing a total of 16 bidirectional data paths. The device operates on a supply voltage range of 4.5 V to 5.5 V and supports TTL input and output levels. Key electrical parameters include a maximum propagation delay of 3.5 ns at a 50 pF load, with balanced output drivers capable of sourcing -24 mA and sinking 24 mA. It functions within an industrial temperature range of -40 °C to +85 °C.

Feature Summary

• Dual configuration supporting two independent 8-bit bidirectional data buses
• High-speed CMOS technology enabling low power consumption and fast switching
• Balanced output drivers designed to minimize system switching noise
• Industrial temperature rating for reliable operation in demanding environments

Applications

• Memory address latching in computer systems
• I/O port buffering and driving
• Bus driver implementations for high-speed data transfer
• Clock buffers and line drivers

Procurement Notes

Verify the specific suffix 'CTPAG' against manufacturer documentation to confirm package type, lead finish, and RoHS compliance status. Ensure the source document explicitly identifies this part as a dual 8-bit transceiver rather than a single buffer variant. Cross-reference the manufacturer's current product status to determine if the component is active or obsolete before procurement.

Selection Notes

Select this component when a design requires two separate 8-bit bidirectional channels in a compact surface-mount package. It serves as a direct replacement for older ABT family devices where lower power consumption is required. Verify that the system's I/O voltage levels are compatible with the specified TTL thresholds and that the 48-pin TSSOP footprint fits the PCB layout constraints.

Part Context

This component belongs to the Integrated Device Technology (IDT) 74FCT series, which utilizes 0.5 micron CMOS technology. The series is engineered as a high-speed, low-power alternative to standard ABT logic families. The 74FCT162244 specifically provides buffered bidirectional connectivity, distinguishing it from unidirectional drivers like the 74FCT16244.

Replacement Considerations

Publicly confirmed substitute part numbers include Texas Instruments CY74FCT162244CTPVC and Diodes Incorporated PI74FCT162244ATV. These alternatives offer similar functional specifications and pinouts but may differ in manufacturing origin or specific package tolerances.
