The SN74ALVC162834VR from Texas Instruments is a high-performance, 18-bit universal bus driver designed for 1.65-V to 3.6-V VCC operation. This integrated circuit is part of the advanced low-voltage CMOS (ALVC) family, which offers a desirable blend of speed, power efficiency, and noise immunity. It is particularly suitable for driving bus lines or buffer memory address registers.

This device features 18-bit universal bus drivers with 3-state outputs that can be independently controlled, making it highly versatile for various applications, including computing, networking, and telecommunications. The SN74ALVC162834VR is organized as two 1-bit to 9-bit drivers with separate output-enable (OE) inputs, which allow for the independent control of each section.

Designed with an edge-rate control circuit that significantly reduces noise due to output transition, this product ensures minimal disturbance on the bus lines. This makes it suitable for high-speed applications where signal integrity is paramount. The device operates at -40°C to 85°C, which allows it to be used in environments with a wide range of temperatures.

The SN74ALVC162834VR comes in a fine-pitch TSSOP (thin shrink small outline package) that is designed for space-saving on PCBs. Its pinout is optimized to reduce crosstalk and simplify the PCB layout. The inputs can tolerate voltages up to 5.5V, even when the device is powered off, adding to its robustness and reliability.

Key features of the SN74ALVC162834VR include:

• Operates from 1.65 V to 3.6 V
• Inputs accept voltages to 5.5 V
• Max tpd of 3.8 ns at 3.3 V
• ±24-mA output drive at 3.3 V
• Bus hold on data inputs eliminates the need for external pullup/pulldown resistors
• Latch-up performance exceeds 250 mA per JESD 17
• ESD protection exceeds JESD 22

The SN74ALVC162834VR is a testament to Texas Instruments' commitment to providing high-quality, reliable components for the electronics industry. Its advanced features and robust design ensure that it meets the demanding requirements of modern digital applications.
