Quad TTL/NMOS to PECL*

Translator

The MC10H351 is a quad translator for interfacing data between a

saturated logic section and the PECL section of digital systems when only
a +5.0 Vdc power supply is available. The MC10H351 has TTL/NMOS
compatible inputs and PECL complementary openemitter outputs that
allow use as an inverting/noninverting translator or as a differential line
driver. When the common strobe input is at a low logic level, it forces all
true outputs to the PECL low logic state (

+3.2 V) and all inverting

outputs to the PECL high logic state (

+4.1 V).

The MC10H351 can also be used with the MC10H350 to transmit and

receive TTL/NMOS information differentially via balanced twisted pair
lines.

(1) Propagation delay is measured on this circuit from +1.5 volts on the input waveform to the 50% point on the output waveform.

NOTE:

Each MECL 10H series circuit has been designed to meet the dc specifications shown in the test table, after thermal equilibrium has been established. The
circuit is in a test socket or mounted on a printed circuit board and transverse air flow greater than 500 lfpm is maintained. Outputs are terminated through
a 50ohm resistor to VCC 2.0 Vdc.
