CERAMIC PACKAGE
CASE 732–03
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 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 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.
