Each of the four identical channels consists 3 2 1 20 19 of a driver with TTL inputs and a receiver with a 1R 4 18 4R TTL output. The driver open-collector output is 1D 5 17 4D designed to handle loads up to 100-mA open NC 6 16 NC collector. The receiver input is internally 2D 7 15 S connected to the driver output, and has a high 2R 8 14 3D impedance to minimize loading of the 9 10 11 12 13 transmission line. Because of the high driver- B D CB R output current and the high receiver-input 2 N N3 3 G impedance, a very large number (typically hundreds) of transceivers may be connected to a NC – No internal connection 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. A strobe turns off all drivers (high impedance) but does not affect receiver operation. These circuits are designed for operation from a single 5-V supply and include a provision to minimize loading of the data bus when the power-supply voltage is zero. The SN55138 is characterized for operation over the full military temperature range of –55°C to 125°C. The SN75138 is characterized for operation from 0°C to 70°C.
