Frequently Asked Questions
What is the 74ALVC16834DGVRE4 and what is it used for?
The 74ALVC16834DGVRE4 is an 18-bit universal bus driver with 3-state outputs from Texas Instruments. It is used to drive data buses in digital systems, providing unidirectional data flow with active-low enable control, making it suitable for applications such as memory interfaces, bus expansion, and high-speed logic level translation in 3.3V systems.
What package does the 74ALVC16834DGVRE4 come in and how many pins does it have?
The 74ALVC16834DGVRE4 is housed in a 56-pin SSOP (Small Outline Package with Shrink pitch) package, designated by the JESD-30 code R-PDSO-G56. This compact surface-mount package is well-suited for high-density PCB designs where board space is at a premium.
What are the key electrical characteristics of the 74ALVC16834DGVRE4?
The 74ALVC16834DGVRE4 supports a load capacitance of 50 pF and provides a maximum output sink current (I(ol)) of 24 mA. It belongs to the ALVC/VCX/A logic family, which is optimized for low-voltage, high-speed operation, typically supporting supply voltages of 1.65V to 3.6V and offering excellent signal integrity for demanding bus applications.
Is the 74ALVC16834DGVRE4 RoHS compliant?
Based on the JESD-609 code 'e4' associated with this part, the 74ALVC16834DGVRE4 is manufactured with lead-free (Pb-free) solder materials in compliance with RoHS (Restriction of Hazardous Substances) directives. However, the Pbfree Code field indicates 'No' for an older product variant, so it is recommended to verify the specific compliance status with Texas Instruments or your distributor before use in restricted applications.
