SN74ALVTH16821VR TI Bus Driver | 56-TVSOP | 2.3-3.6V, 32mA

Product Overview

The SN74ALVTH16821VR is a high-performance 20-bit bus interface driver from Texas Instruments, designed for 2.3V to 3.6V VCC operation. It features 3-state outputs, bus-hold circuitry, and supports partial power-down (Ioff) to prevent backflow current. Housed in a 56-pin TVSOP package, it is ideal for high-speed data bus applications in telecom, computing, and industrial systems.

Detailed Technical Specifications

Key Features

• 20-bit bus interface with 3-state outputs
• Bus-hold circuitry eliminates external pull-up/pull-down resistors
• Partial power-down (Ioff) supports live insertion
• ESD protection exceeds JESD 22 (2000V HBM)
• Latch-up performance exceeds 100mA per JESD 78
• Low static power consumption (ICC = 40µA max)

Target Applications

• 5G base station control boards (e.g., data bus between FPGA and processor)
• Automotive dashboard display interfaces (e.g., connecting MCU to LCD driver)
• Industrial PLC backplane buses
• Telecommunications line cards
