SN74ABT162244DLR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ABT162244DLR is a 16-bit buffer and line driver from the Widebus family, designed for high-performance memory address drivers, clock drivers, and bus-oriented receivers. It operates at a supply voltage of 4.5 V to 5.5 V with an operating temperature range of -40°C to +85°C. The device features noninverting outputs capable of sourcing or sinking up to 12 mA, including equivalent 25-Ω series resistors to reduce overshoot and undershoot. Propagation delays are typically 3.2 ns (tPLH) and 4.0 ns (tPHL) at VCC = 5 V.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Integrated 25-ohm series output resistors minimize external component requirements while reducing signal overshoot and undershoot.
• Ioff circuitry disables outputs during power-down to prevent damaging current backflow through the device.
• Power-up three-state circuitry ensures outputs remain in a high-impedance state during power transitions to prevent driver conflicts.
• Distributed VCC and GND pins are utilized to minimize high-speed switching noise.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the ordering suffix 'DLR' corresponds to the SSOP-48 package and tape-and-reel packaging format. Confirm the specific revision level matches the design requirements. Ensure the supply voltage remains within the 4.5 V to 5.5 V range. Check for RoHS compliance status if required by the manufacturing process. Validate thermal impedance specifications against the PCB layout constraints.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit noninverting buffer with integrated series resistance is required. The Widebus architecture optimizes PCB layout through its flow-through pin configuration. Consider the Ioff and power-up three-state features for hot-insertion applications. Verify that the 12 mA drive capability meets the load requirements of the destination circuits.
