74ABTH162245ADGG:1

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74ABTH162245ADGG:1 is a 16-bit bus transceiver featuring integrated 30 Ω series termination resistors and 3-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V. The device supports BiCMOS technology for high-speed performance and direct TTL level interfacing. Key electrical parameters include an output capability of +12 mA/-32 mA, propagation delays ranging from 1.0 ns to 4.9 ns depending on direction and transition, and latch-up performance exceeding 500 mA per JESD 78 Class II Level B. It incorporates IOFF circuitry for partial power-down applications and bus-hold data inputs.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Incorporates bus-hold data inputs to eliminate the need for external pull-up resistors on unused inputs
• Features integrated 30 Ω series termination resistors for signal integrity
• Provides IOFF circuitry to disable outputs and prevent backflow current during partial power-down
• Utilizes multiple VCC and GND pins to minimize switching noise and ground bounce

Buffers, Drivers, Receivers, Transceivers Applications

• High-speed bidirectional bus interfaces
• Partial power-down system architectures
• Mixed voltage environments requiring direct TTL level interfacing

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required package variant and temperature range. Confirm that the 'H' designation in the part number corresponds to the inclusion of bus-hold functionality, as this distinguishes it from the non-bus-hold version. Ensure compatibility with the 4.5 V to 5.5 V supply voltage requirements for your target application design.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit wide interface with integrated termination is required. The presence of bus-hold inputs simplifies PCB layout by removing the need for external pull-up components on floating lines. Consider the BiCMOS technology benefits for applications demanding both high speed and strong output drive capabilities within a standard 5 V logic environment.

Buffers, Drivers, Receivers, Transceivers Part Context

This component belongs to the 74ABT/ABTH162245A family of 16-bit bus transceivers manufactured by Nexperia. It is designed for high-performance digital systems requiring reliable data transmission across wide buses. The TSSOP48 package (SOT362-1) provides a compact footprint suitable for space-constrained designs while maintaining thermal efficiency through distributed power and ground pins.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74ABT162245ADGG:1 serves as the non-bus-hold equivalent within the same family. Verify if the absence of bus-hold functionality is acceptable for the specific application before substituting.
