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 th...
