SN74ALVCH162344DLR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVCH162344DLR is a 1-bit to 4-bit address driver with 3-state outputs, operating from 1.65 V to 3.6 V. It features a maximum propagation delay of 4.4 ns at 3.3 V and ±12-mA output drive capability. The device includes equivalent 26-Ω series resistors to reduce overshoot and undershoot without external components. Bus hold on data inputs eliminates the need for external pullup/pulldown resistors. Latch-up performance exceeds 250 mA per JESD 17.
