DESCRIPTION

The STLVDS47 is a quad CMOS flow-through
differential line driver designed for applications
requiring ultra low power dissipation and high data
rate. The device is designed to support data rates
in excess of 400Mbp s (200 MHz) utilizing Low
Voltage Differential Signaling (LVDS) techology.
The STLVDS47 accepts low voltage TTL/CMOS
input levels and translates them to low voltage

STLVDS47

SO-16 TSSOP

(350 mV) differential output signals. In addition,
the driver support a TRI-STATE function that may
be used to disable the output stage, disabling the
load current, and thus dropping the device to an
ultra low idle power state of 1.3mW typical. The
STLVDS47 has a flow-through pinout f or easy
PCB layout.
The E N and EN* inputs are AN Ded together and
control the TRI-STATE output.
TheSTLVDS47andcompanionlinereceiver
(STLVDS48) provide a new alternative to high
power pseudo-ECL devices for high-speed
point-to-point interface applications.
