SN74LVTZ244中文资料具有总线保持、TTL 兼容型 CMOS 输入和三态输出的 8 通道、2.7V 至 3.6V 缓冲器数据手册TI规格书

描述 Description

These octal buffers/drivers are designed specifically for low-voltage (3.3-V) VCC operation with the capability to provide a TTL interface to a 5-V system environment.These devices are organized as two 4-bit line drivers with separate output-enable () inputs. Whenis low, the device passes data from the A inputs to the Y outputs. Whenis high, the outputs are in the high-impedance state.Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.The SN74LVTZ244 is available in TI's shrink small-outline package (DB), which provides the same I/O pin count and functionality of standard small-outline packages in less than half the printed-circuit-board area.The SN54LVTZ244 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74LVTZ244 is characterized for operation from -40°C to 85°C.
