SN74VMEH22501ADGGR TI Universal Bus Transceiver | 48-TSSOP | 3.3V, 8-Bit

Product Overview

The SN74VMEH22501ADGGR is a high-performance 8-bit universal bus transceiver from Texas Instruments, designed for bidirectional voltage-level translation and data communication between two independent buses. Housed in a compact 48-TSSOP package, this device operates at a nominal supply voltage of 3.3V and supports mixed-voltage systems with 5V tolerance on I/O pins. It features direction control (DIR) and output enable (OE) inputs, making it ideal for asynchronous communication in high-speed digital systems. The device is part of TI's VMEH family, optimized for VMEbus and other backplane applications, offering robust signal integrity and low propagation delay.

Detailed Technical Specifications

Key Features

• Bidirectional voltage-level translation between 3.3V and 5V systems
• Low propagation delay (3.5 ns typical) for high-speed data transfer
• High output drive capability (±24 mA) for driving heavily loaded buses
• Power-off protection: inputs and outputs are high-impedance when VCC = 0V
• 5V tolerant inputs for mixed-voltage environments
• ESD protection exceeds JESD 22 (2000V HBM, 1000V CDM)
• Supports partial power-down mode (Ioff) to prevent backflow current
• Packaged in 48-TSSOP for space-constrained designs

Target Applications

• VMEbus and VXS backplane systems
• 5G base station control and data boards
• Automotive infotainment and dashboard clusters
• Industrial automation PLC and I/O modules
