SN74LVT16835DLR

Overview

The SN74LVT16835DLR is an 18-bit universal bus driver utilizing Advanced BiCMOS (ABT) technology for 3.3-V operation. It supports mixed-mode signal environments with 5-V input and output voltage tolerance while operating on a 2.7-V to 3.6-V supply. The device features flow-through architecture, distributed VCC/GND pins to minimize switching noise, and active bus-hold circuitry on data inputs. It includes latch/flip-flop functionality controlled by OE, LE, and CLK signals, providing 3-state outputs.

Feature Summary

• Supports mixed-mode signal operation allowing 5-V tolerant interfaces with 3.3-V systems
• Active bus-hold circuitry eliminates the need for external pullup or pulldown resistors
• Distributed power and ground pin configuration minimizes high-speed switching noise
• Flow-through architecture optimizes printed circuit board layout

Applications

• High-density memory mapping
• Clock drivers
• Bus-oriented architectures

Procurement Notes

Verify the specific ordering suffix against current Texas Instruments documentation to confirm package type and status. The DL suffix indicates a shrink small-outline package. Confirm RoHS compliance and environmental classification details directly from the manufacturer's latest datasheet or packaging information addendum before finalizing procurement specifications.

Selection Notes

Select this component for designs requiring 18-bit data transfer with latching capabilities in a 3.3-V environment. Ensure the design accommodates the 5-V input tolerance if interfacing with legacy logic. Verify that the SSOP-56 package dimensions fit the available PCB real estate, considering the 25-mil center-to-center spacing provided by the shrink package option.

Part Context

This device belongs to the Widebus family of logic components, designed to provide increased I/O density within standard small-outline footprints. It is part of the ABT logic series, which combines advanced BiCMOS speed with low static power dissipation. The SN74LVT16835 serves as a bridge between lower voltage logic domains and 5-V system buses.

Replacement Considerations

Check for SN74LVT16835DGGR (TSSOP-56) if a thin shrink small-outline package is preferred over the standard shrink SSOP. Verify functional compatibility with other 18-bit universal bus drivers in the LVT or ALVCH families, ensuring voltage levels and pinouts match.
