description
The SN75ALS125 and SN75ALS127 are
monolithic seven-channel line receivers designed
to satisfy the requirements of the IBM System
360/370 input/output interface specifications.
Employing the IMPACT process allows low
supply-current requirements while maintaining
fast switching speeds and high-current TTL
outputs.
The SN75ALS125 and SN75ALS127 are
characterized for operation from 0°C to 70°C.
