Texas Instruments Logic - Universal Bus Functions SN74VMEH22501ZQLR

The SN74VMEH22501ZQLR is an 8-bit universal bus transceiver designed for 3.3-V VCC operation with 5-V tolerant inputs. It features two integral 1-bit three-wire bus transceivers and supports transparent, latched, and clocked modes of data transfer. The device is compliant with VME64, 2eVME, and 2eSST protocols, making it suitable for high-speed backplane applications. This transceiver incorporates OEC,Ñ¢ circuitry to enhance signal integrity and reduce electromagnetic interference (EMI). It includes a split LVTTL port that provides a feedback path for control and diagnostics monitoring. The B-port outputs are optimized for driving large capacitive loads, while the device supports live insertion with I_off, power-up 3-state, and BIAS V_CC features to prevent backflow current and ensure high-impedance states during power transitions. The SN74VMEH22501ZQLR is designed for high-speed operation and is capable of achieving significant data transfer rates in VME systems, making it a viable option for engineers looking for reliable bus transceivers in their designs.
