SN74LVTH16835DLR

Overview

The SN74LVTH16835DLR is an 18-bit universal bus driver from Texas Instruments, utilizing Advanced BiCMOS Technology (ABT) for 3.3-V operation. It features a wide supply voltage range of 2.7 V to 3.6 V and operates within a temperature range of -40°C to +85°C. The device provides three-state outputs with high drive capabilities, including a maximum output current of 32 mA at low levels and 64 mA at high levels. It is housed in a 56-pin SSOP package.

Feature Summary

• Supports 3.3-V operation using state-of-the-art Advanced BiCMOS Technology (ABT).
• Functions as an 18-bit universal bus driver with configurable direction control.
• Provides three-state outputs to facilitate efficient data transfer on buses.

Applications

• High-density data acquisition systems
• Memory mapping controllers
• Consumer products requiring 3.3-V logic interfacing

Procurement Notes

Verify the specific suffix 'DLR' corresponds to the tape-and-reel packaging configuration required for your assembly process. Confirm that the 3.3-V supply voltage aligns with your system design, as this component is not rated for 5-V logic levels. Ensure thermal management considerations are addressed given the power dissipation characteristics of 18-bit drivers under load.

Selection Notes

Select this component when designing systems that require 18-bit parallel data transmission at 3.3 V. It is suitable for applications needing robust drive strength and low static power consumption. Compare against standard CMOS alternatives if higher voltage tolerance or different pin configurations are required for your specific board layout constraints.

Part Context

This part belongs to the Widebus Family of logic ICs from Texas Instruments. It is designed to interface between microprocessors and peripheral devices in 3.3-V environments. The ABT technology offers improved performance over older LS or HC families, providing faster switching speeds and better noise immunity for modern digital systems.

Replacement Considerations

Check for direct cross-reference parts such as the SN74LVC16835 series if lower voltage operation (1.65 V to 3.6 V) is acceptable. Verify pin compatibility with the SN74ACT16825 if migrating from 5-V systems, noting significant voltage and drive current differences.
