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.
