SEMICONDUCTOR TECHNICAL DATA
The MC10H125 is a quad translator for interfacing data and control signals
between the MECL section and saturated logic section of digital systems. The
10H part is a functional/pinout duplication of the standard MECL 10K family
part, with 100% improvement in propagation delay, and no increase in
power–supply current.
Outputs of unused translators will go to low state when their inputs are left
open.
• Propagation Delay, 2.5 ns Typical • Voltage Compensated
• Improved Noise Margin 150 mV • MECL 10K–Compatible

MC10H125
APPLICATION INFORMATION
The MC10H125 incorporates differential inputs and
Schottky TTL “totem pole” outputs. Differential inputs
allow for use as an inverting/non–inverting translator or
as a differential line receiver . The VBB reference voltage
is available on Pin 1 for use in single–ended input biasing.
The outputs of the MC10H125 go to a low–logic level
whenever the inputs are left floating, and a high–logic
output level is achieved with a minimum input level of 150
mV
.
p–p
An advantage of this device is that MECL–level
information can be received, via balanced twisted pair
lines, in the TTL equipment. This isolates the MECL–logic
from the noisy TTL environment. Power supply
requirements are ground, +5.0 volts and –5.2 volts.
