SN74VMEH22501ADGVR (TEXAS INSTRUMENTS)
Приемопередатчик шины, 8 каналов, 64мА, 3.15В до 3.45В, TVSOP-48
The SN74VMEH22501ADGVR is a 8-bit Universal Bus Transceiver has two integral 1-bit three-wire bus transceivers and is designed for 3.3V VCC operation with 5V tolerant inputs. The UBT™ transceiver allows transparent, latched and flip-flop modes of data transfer and the separate LVTTL input and outputs on the bus transceiver provides a feedback path for control and diagnostics monitoring. This device provides a high-speed interface between cards operating at LVTTL logic levels and VME64, VME64x or VME320 backplane topologies. high-speed backplane operation is a direct result of the improved OEC™ circuitry and high drive that has been designed and tested into the VME64x backplane model. The B-port I/Os are optimized for driving large capacitive loads and include pseudo-ETL input thresholds (1/2 VCC ±50mV) for increased noise immunity. These specifications support the 2eVME protocols in VME64x (ANSI/VITA 1.1) and 2eSST protocols in VITA 1.5.
