SN74LVTH16501DGG

Overview

The SN74LVTH16501DGG is an 18-bit universal bus transceiver from the Texas Instruments LVTH series, housed in a 56-pin SSOP package. It operates on a single power supply ranging from 2.7V to 3.6V. The device features three-state outputs with high drive capabilities of 32mA for high-level and 64mA for low-level states. Propagation delay is typically 5.6ns at 3.3V. It supports industrial temperature ranges from -40°C to +85°C and includes configurable VCC and GND pins for flexible system integration.

Feature Summary

• Provides 18-bit bidirectional data transmission capability within a single integrated circuit
• Features high-drive three-state outputs capable of driving buses and termination resistors directly
• Supports mixed-voltage operation allowing interfacing between 3.3V and 5V systems
• Configurable VCC and GND pins enable independent voltage selection for different bus segments

Applications

• Mobile applications requiring low-power data transmission
• Consumer products utilizing 3.3V or 5V logic interfaces
• Computing platforms needing high-density bus expansion
• Telecommunications equipment requiring reliable signal routing

Procurement Notes

Verify the specific suffix 'DGG' against official Texas Instruments documentation to confirm the exact pinout and mechanical dimensions associated with the 56-SSOP package variant. Ensure that the ordering information matches the required tape-and-reel or tube packaging specifications defined in the manufacturer's latest datasheet revision. Cross-reference the component marking code to distinguish it from similar ALVCH or ABT series devices.

Selection Notes

Select this component when designing systems that require 18-bit wide data paths with mixed-voltage compatibility. The LVTH series offers a balance of speed and drive strength suitable for general-purpose bus applications. Consider the 56-SSOP package constraints regarding board space and thermal dissipation. Verify that the operating voltage range aligns with the target system's power supply rails before finalizing the design.
