SN74ALVC162334DGVR

Universal Bus Functions Overview

The SN74ALVC162334DGVR is a 16-bit universal bus driver with 3-state outputs manufactured by Texas Instruments. It operates from 1.65 V to 3.6 V and features a maximum propagation delay of 3.8 ns at 3.3 V. The device provides ±12-mA output drive capability and includes equivalent 26-Ω series resistors within the output ports to reduce overshoot and undershoot, eliminating the need for external components. Designed to comply with JEDEC 168-Pin and 200-Pin SDRAM buffered DIMM specifications, it ensures latch-up performance exceeds 250 mA per JESD 17. ESD protection exceeds JESD 22 standards, including 2000-V human-body model and 1000-V charged-device model ratings.
