Texas Instruments SN74VMEH22501 8-Bit Universal Bus Transceiver and Two 1-Bit Bus Transceivers with 3-State Outputs 74VMEH22501DGGRE4

The SN74VMEH22501 is an 8-bit universal bus transceiver that includes two integral 1-bit bus transceivers, designed for 3.3-V operation with 5-V tolerant inputs. It supports multiple data transfer modes, including transparent, latched, and clocked modes, making it versatile for various applications. The device features a split LVTTL port that provides a feedback path for control and diagnostics monitoring, enhancing system reliability. This transceiver is compliant with VME64, 2eVME, and 2eSST protocols, making it suitable for high-speed backplane applications. It is optimized for driving large capacitive loads and includes active bus-hold circuitry to maintain valid logic states on unused inputs. The device supports live insertion capabilities, with features such as I_{off} and power-up 3-state outputs to prevent driver conflicts during power transitions. The SN74VMEH22501 is characterized by its improved signal integrity and reduced electromagnetic interference due to its OEC,Ñ¢ circuitry. It is fully specified for high-speed operation and is designed to minimize switching noise through distributed power and ground pins. This product is available in various package options, including TSSOP and BGA, and is suitable for applications requiring robust performance in demanding environments.
