74ABT162244DGGRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ABT162244DGGRG4 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 symmetrical active-low output-enable inputs. The device provides noninverting outputs capable of sourcing or sinking up to 12 mA. Outputs include equivalent 25-Ω series resistors to reduce overshoot and undershoot. It supports hot-insertion via Ioff and power-up 3-state circuitry.

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 3-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 FAQ

How does the device handle hot-insertion?

The device supports hot-insertion through Ioff circuitry, which disables outputs to prevent backflow current, and power-up 3-state circuitry, which maintains a high-impedance state during power transitions.

What is the function of the internal series resistors?

The outputs include equivalent 25-Ω series resistors designed to reduce signal overshoot and undershoot without requiring external components.
