SN74ALVC162334DLR

Universal Bus Functions Overview

The SN74ALVC162334DLR is a 16-bit universal bus driver with 3-state outputs manufactured by Texas Instruments. It operates from a supply voltage range 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 and includes equivalent 26-Ω series resistors within the output ports to reduce overshoot and undershoot without requiring external components. It is designed to comply with JEDEC 168-pin and 200-pin SDRAM buffered DIMM specifications.

Universal Bus Functions Feature Summary

• Integrated 26-ohm series resistors in output ports eliminate the need for external resistors to manage signal integrity issues like overshoot and undershoot.
• Supports transparent mode when latch-enable input is low, allowing data storage in the internal latch/flip-flop on the clock transition when latch-enable is high.
• High ESD protection performance exceeding JESD 22 standards for human-body, machine, and charged-device models.

Universal Bus Functions Applications

• PC100 Register DIMMs
• JEDEC 168-pin SDRAM buffered DIMMs
• JEDEC 200-pin SDRAM buffered DIMMs

Universal Bus Functions Procurement Notes

Verify that the SSOP package variant matches the specific pinout requirements for the target PCB layout. Confirm that the operating temperature range aligns with the environmental conditions of the final assembly. Ensure that the OE pin is properly biased during power-up sequences to maintain the required high-impedance state as specified in the datasheet guidelines.

Universal Bus Functions Selection Notes

Select this component for applications requiring wide voltage operation between 1.65 V and 3.6 V. The integrated series resistance simplifies board design by removing the need for discrete damping components. Consider the 48-pin SSOP package constraints regarding thermal dissipation and physical space availability on the circuit board.

Universal Bus Functions Part Context

This device belongs to the Texas Instruments Widebus family of logic products. It serves as a specialized buffer solution for high-speed memory interfaces where signal integrity and precise timing control are critical. The inclusion of built-in termination characteristics distinguishes it from standard bus drivers that require external matching networks.
