74ABTH162245ADGG,1

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74ABTH162245ADGG,1 is a 16-bit bus transceiver with 30 Ω series termination resistors and 3-state outputs. It operates on a supply voltage range of 4.5 V to 5.5 V. The device features two output enables (1OE and 2OE) and two direction control inputs (1DIR and 2DIR). It incorporates bus-hold data inputs to eliminate external pull-up resistors. The package is TSSOP48 (SOT362-1), supporting surface mount installation.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Incorporates integrated 30 Ω series termination resistors for signal integrity
• Features bus-hold data inputs to maintain unused input states without external components
• Includes IOFF circuitry to prevent damaging backflow current during partial power-down
• Provides BiCMOS high-speed performance with direct interface capability to TTL levels

Buffers, Drivers, Receivers, Transceivers Applications

• High-speed bidirectional bus interfaces
• Partial power-down applications requiring controlled leakage
• Mixed-signal systems utilizing TTL level interfacing

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required temperature range and package variant. Confirm that the 'H' designation in the part number corresponds to the inclusion of the bus hold feature as specified in the manufacturer's documentation. Ensure compatibility with the intended PCB footprint and soldering profile for the TSSOP48 package.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit wide bus interface is required with integrated termination resistors. The presence of bus hold functionality distinguishes it from the non-bus-hold variant. Consider the 4.5 V to 5.5 V operating range and BiCMOS speed characteristics against system requirements. Verify ESD protection ratings meet the environmental standards of the target application.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74ABT/ABTH162245A family of 16-bit bus transceivers manufactured by Nexperia. It utilizes BiCMOS technology to achieve high-speed operation while maintaining strong output drive capabilities. The family supports configurations for both 8-bit and 16-bit data paths within a single package.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74ABT162245ADGG,1 serves as a functional substitute but lacks the bus hold feature found in the ABTH variant.
