Description

The N8T14, SN55122, and SN75122 are triple line receivers that are designed for digital data transmission over lines having impedances from 50 W to 500 W. They are also compatible with standard TTL-logic and supply voltage levels.

The N8T14, SN55122, and SN75122 have receiver inputs with built-in hysteresis to provide increased noise margin for single-ended systems. The high impedance of this input presents a minimum load to the driver and allows termination of the transmission line in its characteristic impedance to minimize line reflection. An open line will affect the receiver input as would a low-level voltage. The receiver N8T14, SN55122, and SN75122 can withstand a level of 0.15 V with power on or off. The other inputs of N8T14, SN55122, and SN75122 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, will hold the output low. The third receiver has only an A input that, if high, will hold the output low.

The SN55122 is characterized for operation over the full military temperature range of 55°C to 125°C. The N8T14 and SN75122 are characterized for operation from 0°C to 70°C.
