1 / 6 page SN75124 TRIPLE LINE RECEIVER SLLS058B – SEPTEMBER 1973 – REVISED MAY 1995 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Meets or Exceeds the Requirements of IBM ™ System 360 Input/Output Interface Specification D Operates From Single 5-V Supply D TTL Compatible D Built-In Input Threshold Hysteresis D High Speed . . . Typical Propagation Delay Time = 20 ns D Independent Channel Strobes D Input Gating Increases Application Flexibility D Designed for Use With Dual Line Driver SN75123 D Designed to Be Interchangeable With Signetics N8T24 description The SN75124 triple line receiver is specifically designed to meet the input/output interface specifications for IBM System 360. It is also compatible with standard TTL logic and supply voltage levels. The SN75124 has receiver inputs with built-in hysteresis to provide increased noise margin for single-ended systems. An open line affects the receiver input as does a low-level input voltage, and the receiver input can withstand a level of – 0.15 V with power on or off. The other inputs are in TTL configuration. The S input must be high to enable the receiver input. Two of the line receivers have A and B inputs that, if both are high, hold the output low. The third receiver has only an A input that, if high, holds the output low. See the SN751730 for new IBM 360/370 interface designs. The SN75124 is characterized for operation from 0 °C to 70°C.
