SY10H352
SY10H352
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.
Single 5V power supply
All VCC pins isolated on chip
Differentially drive balanced lines
tpd 1.3ns typical
