D OR N PACKAGE (TOP VIEW) The SN75125 and SN75127 are monolithic seven-channel line receivers designed to satisfy the requirements of the IBM System 360/370 input/output interface specifications.
Special low-power design and Schottky-clamped transistors allow for low supply-current requirements while maintaining fast switching speeds and high-current TTL outputs.
The SN75125 and SN75127 are characterized for operation from 0°C to 70°C.
