Texas Instruments SN75124

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. view all in datasheet
