description
The N8T14, SN55122, and SN75122 are triple
line receivers that are designed for digital data
transmission over lines having impedances from
50
to 500
. 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 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, 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.
