SN74ALVC162334DGG

Universal Bus Functions Overview

The SN74ALVC162334DGG is a 16-bit universal bus driver with 3-state outputs from the Texas Instruments Widebus family. 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 outputs 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 high reliability with latch-up performance exceeding 250 mA per JESD 17.

Universal Bus Functions Feature Summary

• Integrated 26-ohm series resistors in output ports to minimize signal overshoot and undershoot without requiring external components
• Transparent data flow controlled by OE input, with latching functionality enabled by LE and CLK inputs
• Compliance with JEDEC standards for 168-pin and 200-pin SDRAM buffered DIMM applications
• Robust ESD protection exceeding specified limits for human-body, machine, and charged-device models

Universal Bus Functions Applications

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

Universal Bus Functions Procurement Notes

Verify the specific package variant (TSSOP DGG) against the datasheet ordering information to ensure compatibility with PCB footprint requirements. Confirm that the supply voltage range of 1.65 V to 3.6 V aligns with the target system design. Ensure proper pullup resistor configuration on the OE pin during power-up to maintain the high-impedance state as recommended in the functional description.

Universal Bus Functions Selection Notes

Select this component when designing systems requiring 16-bit wide data buses with low propagation delay and integrated termination resistance. The device is suitable for applications needing transparent or latched data buffering with 3-state control. Consider the TSSOP-48 package dimensions and thermal characteristics if space constraints are critical. Verify that the input transition rates remain within the specified limits to ensure timing compliance.

Universal Bus Functions Part Context

This part belongs to the ALVC/VCX/A series of logic devices, specifically designed for low-voltage CMOS applications. It is part of the Widebus family, which focuses on high-density bus interfacing solutions. The SN74ALVC162334 complements other bus drivers and transceivers in the portfolio by offering combined buffering and latching capabilities in a single 48-pin package.

Universal Bus Functions Replacement Considerations

Check for SN74ALVC162334DLR or SN74ALVC162334DGVR as alternative package options within the same electrical specification family. Verify pinout compatibility before substituting with different package types.
