74FCT162244ATPAG

Overview

The 74FCT162244ATPAG is a CMOS bus driver manufactured by Renesas Electronics Corporation. It features four non-inverting buffers with three-state outputs, organized as two eight-bit sections within a 48-pin TSSOP package. The device operates on a single power supply ranging from 4.5V to 5.5V. It provides high drive capability with output currents of 24mA for both high and low states. The component supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Four independent non-inverting buffer channels providing signal isolation and amplification
• Three-state output control allowing multiple drivers to share a common bus line
• High current drive capability suitable for driving capacitive loads and transmission lines

Applications

• Parallel data bus buffering in computer systems
• Clock distribution networks requiring signal integrity
• Memory interface circuits for address and data lines

Procurement Notes

Verify the specific suffix 'TPAG' against the manufacturer's official datasheet to confirm pinout compatibility and package dimensions. Ensure the source document explicitly lists this part number as active or available, as logic families often undergo lifecycle changes. Cross-reference the RoHS status and moisture sensitivity level requirements with your assembly process specifications before ordering.

Selection Notes

Select this component when a 5V logic system requires robust buffering for wide parallel buses. The FCT series offers faster switching speeds compared to standard HC logic while maintaining compatible voltage levels. Consider the 48-pin TSSOP footprint for PCB layout constraints. Verify that the required drive current exceeds the load capacitance demands of the connected circuitry.

Part Context

This device belongs to the 74FCT logic family, designed for high-speed CMOS applications. It serves as a bridge between lower-speed control logic and high-speed peripheral interfaces. The 162244 designation indicates a quad buffer configuration, distinct from transceivers like the 245 which support bidirectional data flow.

Replacement Considerations

Public confirmed substitute part numbers include SN74ABT16374ADGGR.
