SN74ALVC162334DL

Universal Bus Functions Overview

The SN74ALVC162334DL 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 supports an operating free-air temperature of -40°C to 85°C. The device features a maximum propagation delay (t_pd) of 3.8 ns at 3.3 V and provides ±12-mA output drive capability. Outputs include equivalent 26-Ω series resistors 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 the output path eliminate the need for external resistors, reducing signal overshoot and undershoot.
• Supports transparent mode when latch-enable is low, or latches data on the low-to-high transition of the clock input.
• Designed to meet JEDEC standards for 168-pin and 200-pin SDRAM buffered DIMM applications.
• ESD protection exceeds JESD 22 limits for human-body, machine-model, and charged-device models.

Universal Bus Functions Applications

• PC100 Register DIMMs
• SDRAM buffered DIMMs compliant with JEDEC 168-pin specifications
• SDRAM buffered DIMMs compliant with JEDEC 200-pin specifications

Universal Bus Functions Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the DL suffix denotes an SSOP package. Confirm RoHS compliance status and moisture sensitivity level ratings against current manufacturing data sheets before procurement. Ensure the component meets the required operating temperature range for the target application environment.

Universal Bus Functions Selection Notes

Select this component for high-speed 16-bit data bus applications requiring integrated termination resistors. It is suitable for systems operating between 1.65 V and 3.6 V where low propagation delay and controlled signal integrity are critical. Consider the 48-pin SSOP package constraints regarding board space and thermal dissipation requirements.

Universal Bus Functions Part Context

This device belongs to the Texas Instruments Widebus family of logic products. It functions as a universal bus driver providing both transparent and latched data paths through dedicated OE, LE, and CLK control inputs. The design integrates standard CMOS technology optimized for low-voltage operation and high-speed performance in memory interface circuits.

Universal Bus Functions Replacement Considerations

Direct substitutes include SN74ALVC162334DGGR and SN74ALVC162334DGVR. Verify pinout compatibility and electrical characteristics match the original design requirements when transitioning between different package types within the same product family.

Universal Bus Functions FAQ

How does the device handle data storage?

Data is stored in the internal latch/flip-flop on the low-to-high transition of the CLK input when the LE input is held high.

What is the purpose of the internal series resistors?

The equivalent 26-ohm resistors are included to reduce signal overshoot and undershoot, removing the need for external termination resistors.
