SN74ALVCH162334VR

Overview

The SN74ALVCH162334VR is a 16-bit universal bus driver with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 3.6 V and supports data rates up to 150 MHz. The device features active bus-hold circuitry on data inputs, eliminating the need for external pullup or pulldown resistors. It includes equivalent 26-Ω series resistors at the output port to reduce overshoot and undershoot. The component is characterized for operation from -40 °C to 85 °C and utilizes an EPIC submicron CMOS process.

Feature Summary

• Integrated active bus-hold circuitry maintains valid logic levels on unused or floating data inputs without requiring external components.
• Built-in equivalent 26-Ω series resistors at the output port minimize signal overshoot and undershoot.
• Designed to comply with JEDEC specifications for buffered SDRAM DIMMs.
• Provides enhanced ESD protection exceeding 2000 V per MIL-STD-883 Method 3015.

Applications

• Buffered SDRAM DIMM designs
• High-speed data bus drivers
• Universal bus interface circuits

Procurement Notes

Verify the specific ordering suffix 'VR' corresponds to the TVSOP (DGV) package configuration when placing orders. Confirm that the required quantity aligns with the standard tape-and-reel packaging size specified in the manufacturer's documentation. Ensure compatibility with the designated operating temperature range and voltage requirements for your target application before finalizing procurement.

Selection Notes

Select this component for applications requiring 16-bit data buffering with latching capabilities and high-speed performance up to 150 MHz. Consider the integrated series resistors and bus-hold features if minimizing external passive components is a priority. Verify that the 1.65-V to 3.6-V supply voltage range matches the system power architecture and that the TVSOP package fits the available PCB footprint constraints.
