SN75138 四路总线收发器
              
The SN55138 and SN75138 quadruple bus transceivers are designed for two-way   data communication over single-ended transmission lines. Each of the four   identical channels consists of a driver with TTL inputs and a receiver with a   TTL output. The driver open-collector output is designed to handle loads up to   100-mA open collector. The receiver input is internally connected to the driver   output, and has a high impedance to minimize loading of the transmission line.   Because of the high driver-output current and the high receiver-input impedance,   a very large number (typically hundreds) of transceivers may be connected to a   single data bus. 
              The receiver design also features a threshold of 2.3 V (typical), providing a   wider noise margin than would be possible with a receiver having the usual TTL   threshold
