DESCRIPTION

s Single 5V power supply

s All V

s Differentially drive balanced lines

s t

s Fully compatible with MC10H352

s Available in 20-pin PLCC package

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.
