SN74VMEH22501A-EP 增强型产品 8 位通用总线收发器和 2 个 1 位总线收发器

The SN74CVMEH22501A-EP 8-bit universal bus transceiver has two integral 1-bit three-wire bus transceivers and is designed for 3.3-V VCC operation with 5-V tolerant inputs. The UBTTM transceiver allows transparent, latched, and flip-flop modes of data transfer, and the separate LVTTL input and outputs on the bus transceivers provide 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.

The SN74CVMEH22501A-EP is pin-for-pin capatible to the VMEH22501, but operates at a wider operating temperature (-40°C to 85°C) range.

High-speed backplane operation is a direct result of the improved OECTM circuitry and high drive that has been designed and tested into the VME64x backplane model
