MC10H125
Quad MECL−to−TTL
Translator
Description
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.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.

NOTE: Device will meet the specifications after thermal equilibrium has been established when mounted in a test socket or printed circuit
board with maintained transverse airflow greater than 500 lfpm. Electrical parameters are guaranteed only over the declared
operating temperature range. Functional operation of the device exceeding these conditions is not implied. Device specification limit
values are applied individually under normal operating conditions and not valid simultaneously.

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 V
BB
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 V and
−5.2
V.
