Texas Instruments N8T14
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. 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.| Part No. | N8T14 |
