SN74ALVC162834VR

Universal Bus Functions Overview

The SN74ALVC162834VR is an 18-bit universal bus driver with 3-state outputs from the Texas Instruments Widebus family. It operates from a supply voltage of 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 at 3.3 V. Outputs include equivalent 26-Ω series resistors to eliminate the need for external components. Latch-up performance exceeds 250 mA per JESD 17, and ESD protection meets JESD 22 standards.

Universal Bus Functions Feature Summary

• Supports data flow control via output-enable (OE) input and transparent or latched modes controlled by latch-enable (LE) and clock (CLK) inputs.
• Outputs feature integrated equivalent 26-Ω series resistors designed to reduce overshoot and undershoot without requiring external resistors.
• Provides high-impedance state when OE is high, ensuring safe power-up/down states when tied to VCC through a pullup resistor.

Universal Bus Functions Applications

• High-speed data buffering in portable systems
• Clock drivers and buffer circuits
• Multipoint bus transmission applications

Universal Bus Functions Procurement Notes

Verify the specific ordering suffix 'VR' corresponds to the TVSOP package and tape-and-reel quantity as defined in the manufacturer's documentation. Confirm that the component status remains active for new designs and check for any recent environmental compliance updates regarding lead-free specifications before finalizing procurement orders.

Universal Bus Functions Selection Notes

Select this component for designs requiring wide voltage operation between 1.65 V and 3.6 V with high-speed data transfer capabilities. Consider the integrated series resistance for simplified PCB layout and signal integrity management. Ensure the application environment stays within the recommended operating temperature range of -40°C to 85°C.
