SN74LVT16835DGGR

Overview

The SN74LVT16835DGGR is an 18-bit universal bus driver utilizing Advanced BiCMOS Technology (ABT) for 3.3-V operation with low static power dissipation. It supports mixed-mode signal environments, allowing 5-V input and output voltages alongside 3.3-V VCC. The device features 3-state outputs and operates from a supply voltage range of 2.7 V to 3.6 V. It includes active bus-hold circuitry on data inputs to eliminate external pullup or pulldown resistors. The component is characterized for operation within a temperature range of -40°C to +85°C.

Feature Summary

• Supports mixed-mode signal operation with 5-V tolerant I/O capabilities in a 3.3-V system environment.
• Features active bus-hold circuitry on data inputs to maintain valid logic levels without external components.
• Utilizes distributed VCC and GND pin configuration to minimize high-speed switching noise.
• Provides flow-through architecture to optimize printed circuit board layout efficiency.

Applications

• Mixed-mode signal processing between 5-V and 3.3-V logic systems
• Unregulated battery-powered equipment operation down to 2.7 V
• Live insertion applications requiring robust input protection

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and environmental compliance. Confirm that the NRND status does not conflict with long-term production requirements. Ensure design-in validation accounts for the recommended operating conditions specified in the official datasheet prior to final procurement.

Selection Notes

Select this component when designing interfaces requiring 18-bit data transfer between mixed-voltage domains. Verify that the 3.3-V supply voltage aligns with the target system architecture. Consider the TSSOP-56 package dimensions for PCB space constraints. Evaluate the ABT technology benefits regarding ground bounce performance and power consumption relative to standard CMOS alternatives.

Part Context

This device belongs to Texas Instruments' Widebus family, designed to provide high-density I/O functionality in compact packages. It represents the ABT logic series, which combines advanced BiCMOS technology with TTL-compatible interfaces. The DGGR suffix indicates a Thin Shrink Small-Outline Package (DGG) supplied in tape and reel format for automated surface-mount assembly processes.

Replacement Considerations

Consult the manufacturer's product selection guide for direct functional equivalents within the same logic family. Verify pin compatibility and electrical specifications before substituting with other wide-bus drivers. Cross-reference package dimensions to ensure mechanical fit during replacement scenarios.
