SN74LS245中文资料八路总线收发器数据手册TI规格书

描述 Description

These octal bus transceivers are designed for asynchronous two-way communication between data buses. The control-function implementation minimizes external timing requirements.
The SNx4LS245 devices allow data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE) input can disable the device so that the buses are effectively isolated.

特性 Features

• 3-State Outputs Drive Bus Lines Directly
• PNP Inputs Reduce DC Loading on Bus Lines
• Hysteresis at Bus Inputs Improves Noise Margins
• Typical Propagation Delay Times Port to Port, 8 ns
