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.
