CD74FCT162245ATMT96

Overview

The CD74FCT162245ATMT96 is a Fast CMOS (FCT) 16-bit bidirectional bus transceiver manufactured by Harris Corporation. It integrates two independent 8-bit transceivers within a single package, facilitating data transfer between two 8-bit buses. The device operates with a supply voltage range of 4.75 V to 5.25 V and supports an extended commercial temperature range from -40 °C to +85 °C. Key electrical characteristics include a typical propagation delay of 4.6 ns and a load capacitance rating of 50 pF. It utilizes a 48-pin Thin Shrink Small Outline Package (TSSOP).

Feature Summary

• Dual 8-bit architecture providing two independent bidirectional data paths for efficient system interconnects.
• Bus hold inputs eliminate the need for external pull-up resistors on unused or floating lines.
• Power-off disable feature allows outputs to be disabled when VCC is off, supporting live insertion.

Applications

• High-speed memory bus architectures requiring bidirectional data flow.
• Clock distribution networks utilizing the bus hold functionality.
• Bidirectional gate drivers in complex digital logic systems.

Procurement Notes

Verify the manufacturer designation as Harris Corporation, noting that this entity was acquired by Intersil and subsequently Renesas. Confirm the specific suffix '96' corresponds to the intended tape-and-reel packaging configuration. Ensure the component meets the required RoHS status, as indicated by the 'e0' JESD-609 code in related datasheets, which may imply lead-based composition depending on the production era.

Selection Notes

Select this component when a dual-channel 16-bit transceiver is required for high-speed CMOS applications. It serves as a direct replacement for older ABT series devices, offering improved speed and lower power consumption. The inclusion of bus hold inputs simplifies PCB layout by removing the necessity for discrete pull-up components on control lines.

Part Context

This part belongs to the FCT (Fast CMOS) family, designed to replace faster Bipolar TTL technologies like ABT. The CD74 prefix indicates it is a Harris Corporation product. The '162245' designation specifies a dual 8-bit non-inverting transceiver with bus hold capabilities. This family bridges the performance gap between standard 74F and 74ACT logic families.

Replacement Considerations

Compatible substitutes include IDT74FCT162245ATE and PI74FCT162245T. Verify pin compatibility and ensure the alternative manufacturer's package dimensions match the 48-pin TSSOP form factor.
