SN74LVTH16835DL

Overview

The SN74LVTH16835DL is an 18-bit universal bus driver from Texas Instruments, operating within a 2.7 V to 3.6 V supply voltage range. It features three-state outputs and supports bidirectional data transmission with configurable direction control. The device utilizes ABT technology to achieve low power consumption while maintaining high-speed performance, with a maximum propagation delay of 3.5 ns at nominal voltage. It operates reliably across a temperature range of -40°C to +85°C and is housed in a 56-pin SSOP package.

Feature Summary

• Provides 18-bit universal bus driving capability for high-density data buses
• Supports bidirectional data flow with independent direction control inputs
• Features three-state outputs to facilitate direct connection to system buses
• Utilizes ABT technology for optimized power dissipation and speed

Applications

• High-performance computing systems requiring wide data bus interfaces
• Memory mapping and storage subsystems
• Industrial control networks with multiple data lines
• Communication equipment utilizing parallel data transfer

Procurement Notes

Verify the specific suffix 'DL' corresponds to the 56-SSOP package variant when sourcing. Confirm that unused control inputs are properly terminated to VCC or GND as per datasheet requirements to ensure stable operation. Check RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure the supply voltage remains strictly within the 2.7 V to 3.6 V limits to prevent device damage.

Selection Notes

Select this component when an 18-bit width is required for bus interfacing rather than standard 8-bit or 16-bit alternatives. Consider the ABT technology benefits over standard LVT series for improved switching characteristics. Evaluate the 56-SSOP footprint against available PCB space constraints. Compare propagation delays against system clock speeds to ensure timing margins are met for the target application frequency.

Part Context

This part belongs to the SN74LVTH family of 3.3-V ABT logic devices designed for high-speed digital applications. It complements other bus drivers like the SN74LVTH125 by offering greater bit-width capacity. The LVTH series focuses on balancing speed and power efficiency for modern embedded systems.

Replacement Considerations

Check for SN74LVTH16835DGGR which shares identical electrical specifications but differs in packaging type. Verify pinout compatibility before substituting different package variants to avoid board redesign.
