DESCRIPTION
The SY10H352 is a quad translator for interfacing data
between a CMOS logic section and the PECL section of
digital systems when only a +5.0V VDC power supply is
available. The SY10H352 has CMOS 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 (≈ +3.2V) and all inverting outputs to the
PECL high logic state (≈ +4.1V).
The SY10H352 can also be used with the SY10H350
to transmit and receive CMOS information differentially
via balanced twisted pair lines.
