SN74VMEH22501DGVR TI Universal Bus Transceiver | 48-TVSOP | 3.3V, 100MHz

Product Overview

The SN74VMEH22501DGVR is a 22-bit universal bus transceiver from Texas Instruments, designed for 3.3-V VME64x, VME320, and other high-performance backplane applications. It features two 11-bit transceiver channels with separate output-enable and direction-control pins, providing bidirectional voltage-level translation and signal buffering. Housed in a compact 48-pin TVSOP package, this device supports data rates up to 100 MHz and offers bus-hold circuitry to eliminate the need for external pull-up resistors.

Detailed Technical Specifications

Key Features

• Bidirectional voltage-level translation between 3.3-V and 5-V systems
• Bus-hold circuitry eliminates external pull-up/pull-down resistors
• Low propagation delay (3.5 ns typical) for high-speed operation
• Supports live insertion and hot-swap applications
• ESD protection exceeds JESD 22 (2000-V HBM, 1000-V CDM)
• Industrial temperature range (-40°C to +85°C)

Target Applications

• 5G base station backplane communication (e.g., Nokia AirScale, Ericsson Radio System)
• Automotive infotainment and dashboard systems (e.g., Tesla Model 3 central display)
