description
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
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.
