DESCRIPTION

The SY10H351 is a quad translator for interfacing data

between a saturated logic selection and the PECL section

of digital systems when only a +5.0V VDC power supply

is available. The SY10H351 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 (≈ +3.2V) and all inverting

outputs to the PECL high logic state (≈ 4.1V).

The SY10H351 can also be used with the SY10H350

to transmit and receive TTL/NMOS information

differentially via balanced twisted pair lines.
