SN74ALVCH162334DL

Overview

The SN74ALVCH162334DL 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 an operating temperature range from -40 °C to 85 °C. The device utilizes the EPIC submicron process and belongs to the Widebus family. It features active bus-hold circuitry on data inputs, eliminating the need for external pullup or pulldown resistors. The output port includes equivalent 26-Ω series resistors to reduce overshoot and undershoot without requiring external components.

Feature Summary

• Integrated active bus-hold circuitry maintains valid logic levels on unused or floating data inputs, removing the requirement for external pullup or pulldown resistors.
• Output port incorporates equivalent 26-Ω series resistors designed to minimize signal overshoot and undershoot, negating the need for additional external resistance.
• Complies with JEDEC specifications for 168-pin and 200-pin SDRAM buffered DIMM applications.

Applications

• Buffered DIMM designs for 168-pin and 200-pin SDRAM configurations
• High-speed data bus driving in low-voltage systems
• Universal bus drivers requiring transparent and latched modes

Procurement Notes

Verify component authenticity through authorized distributors or TI direct channels. Confirm package type matches design requirements, as the DL variant uses SSOP packaging. Check current production status and availability, as lead times may vary based on manufacturing schedules. Ensure compliance with RoHS standards and moisture sensitivity level ratings before procurement.

Selection Notes

Select this component for applications requiring 16-bit data buffering with both transparent and latched functionality. Consider the 1.65-V to 3.6-V operating range for compatibility with various low-voltage logic families. Evaluate the integrated series resistors and bus-hold features to simplify board layout and reduce external component count compared to standard drivers.

Part Context

This device is part of Texas Instruments' Widebus family, utilizing Enhanced-Performance Implanted CMOS (EPIC) technology. It provides a versatile solution for managing high-density data buses in memory systems. The SN74ALVCH162334DL specifically denotes the Plastic Shrink Small-Outline (DL) package variant, offering surface-mount installation options suitable for automated assembly processes.

Replacement Considerations

Direct substitutes include other SN74ALVCH162334 variants such as SN74ALVCH162334GR (TSSOP) and SN74ALVCH162334VR (TVSOP). Verify pinout compatibility and thermal characteristics when switching between package types. Ensure that any alternative meets the same electrical specifications and JEDEC compliance requirements.
