SN74ABT162244DL

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ABT162244DL is a 16-bit buffer and line driver from the Widebus family, housed in a 48-pin SSOP package. It operates within a supply voltage range of 4.5 V to 5.5 V. The device provides noninverting outputs with symmetrical active-low output-enable inputs. Outputs are capable of sourcing or sinking up to 12 mA and include equivalent 25-ohm series resistors. Propagation delay ranges from 3.2 ns to 4.0 ns at 5 V.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Integrated 25-ohm series resistors reduce overshoot and undershoot without external components
• Ioff circuitry prevents damaging current backflow when powered down
• Power-up 3-state ensures high-impedance state during power transitions
• Distributed VCC and GND pins minimize high-speed switching noise

Buffers, Drivers, Receivers, Transceivers Applications

• 3-state memory address drivers
• Clock drivers
• Bus-oriented receivers and transmitters

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DL' corresponds to the SSOP tube packaging configuration. Confirm that the required operating temperature range aligns with the -40°C to +85°C specification for this catalog version. Ensure input pins are tied to VCC or GND to prevent floating states.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring 16-bit buffering with integrated termination. The Widebus architecture optimizes PCB layout through flow-through design. Verify that the 12 mA drive capability meets load requirements and that the 4.5 V to 5.5 V supply range matches the system voltage.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to Texas Instruments' Widebus family, designed for high-density bus applications. It functions as a single 16-bit buffer or can be configured as four 4-bit buffers. The device supports hot-insertion scenarios due to its specific power-up and Ioff characteristics.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74ABT162244DGGR (TSSOP) and SN74ABT162244DLR (SSOP Tape & Reel) offer identical electrical performance with different packaging formats.
