SN74ALVCH16334DGVR

Overview

The SN74ALVCH16334DGVR is a 16-bit universal bus driver with 3-state outputs, part of the Widebus family. It operates at supply voltages from 1.65 V to 3.6 V and features active bus-hold circuitry on data inputs. The device includes latch-enable (LE) and clock (CLK) inputs for transparent or latched operation. Output port equivalent series resistors reduce overshoot and undershoot without external components. It is characterized for operation from -40°C to 85°C.

Feature Summary

• Active bus-hold circuitry eliminates the need for external pullup/pulldown resistors on data inputs.
• Output port includes equivalent series resistors to reduce signal overshoot and undershoot.
• Designed to comply with JEDEC SDRAM buffered DIMM specifications.

Applications

• SDRAM buffered DIMMs
• High-density data buses
• Universal bus drivers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product selection guide. Confirm package type and moisture sensitivity level requirements before procurement. Ensure the component status matches design intent, as availability may vary by region.

Selection Notes

Select this component for applications requiring 16-bit data buffering with low-voltage compatibility. Consider the internal series resistance for signal integrity in high-speed designs. Verify that the operating voltage range aligns with the system power rails.
