MC10124
Quad TTL to MECL
Translator
The MC10124 is a quad translator for interfacing data and control
signals between a saturated logic section and the MECL section of
digital systems. The MC10124 has TTL compatible inputs, and
MECL complementary open–emitter outputs that allow use as an
inverting/ non–inverting translator or as a differential line driver.
When the common strobe input is at the low logic level, it forces all
true outputs to a MECL low logic state and all inverting outputs to a
MECL high logic state.

Power supply requirements are ground, +5.0 Volts, and –5.2 Volts.
Propagation delay of the MC10124 is typically 3.5 ns. The dc levels
are standard or Schottky TTL in, MECL 10,000 out.

An advantage of this device is that TTL level information can be
transmitted differentially, via balanced twisted pair lines, to the MECL
equipment, where the signal can be received by the MC10115 or
MC10116 differential line receivers. The MC10124 is useful in
computers, instrumentation, peripheral controllers, test equipment,
and digital communications systems.
