description

The N8T14, SN55122, and SN75122 are triple

line receivers that are designed for digital data

transmission over lines having impedances from

50 Ω to 500 Ω. They are also compatible with

standard TTL-logic and supply voltage levels.

NC–No internal connection

THE N8T14 AND SN75122 ARE NOT

RECOMMENDED FOR NEW DESIGN

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.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
