CD74FCT162245ATMT

Overview

The CD74FCT162245ATMT is a 16-bit bidirectional bus transceiver manufactured by Harris Corporation. It integrates two independent 8-bit transceivers within a single 48-pin TSSOP package. The device operates with a supply voltage range of 4.5V to 5.5V and features non-inverting logic. Outputs are three-state, allowing for safe disconnection from the bus. The component is designed for high-speed data transmission applications requiring balanced output drivers to reduce system switching noise.

Feature Summary

• Integrates two independent 8-bit bidirectional transceivers in a compact 48-pin TSSOP package
• Features balanced output drivers to minimize system switching noise
• Supports three-state outputs for effective bus isolation
• Operates within a standard 4.5V to 5.5V supply voltage range

Applications

• High-speed data bus interfaces
• Memory module data routing
• Bidirectional data transfer between microprocessors and peripherals

Procurement Notes

Verify the manufacturer designation as Harris Corporation on the component marking. Confirm the 48-TSSOP package type and the specific suffix ATMT for tape-and-reel packaging if required. Ensure the operating voltage requirements align with the 4.5V to 5.5V specification before integration into the design.

Selection Notes

Select this component when a 16-bit bidirectional interface is required with low noise characteristics. The balanced driver configuration makes it suitable for applications sensitive to switching noise. Verify that the 48-pin TSSOP footprint matches the PCB layout constraints and that the 5V logic family compatibility meets the system voltage levels.

Part Context

This part belongs to the FCT (Fast CMOS) logic family, known for high speed and low power consumption. It serves as a bridge between different logic families or buses, facilitating efficient data movement. The Harris Corporation variant maintains the electrical characteristics defined by the FCT standard while offering specific packaging options for surface mount assembly.

Replacement Considerations

Check for direct pin-compatible alternatives from other manufacturers such as Diodes Incorporated PI74FCT162245 series. Verify that any substitute maintains the same 48-pin TSSOP package and 3-state output functionality. Ensure the replacement supports the same 4.5V to 5.5V operating range.
