FEATURES
DESCRIPTION
The DS90C031B is a quad CMOS differential line
driver designed for applications requiring ultra low
power dissipation and high data rates. The device
supports data rates in excess of 155.5 Mbps (77.7
MHz) and uses Low Voltage Differential Signaling
(LVDS) technology.

>155.5 Mbps (77.7 MHz) switching rates
High impedance LVDS outputs with power-off
±350 mV differential signaling
Ultra low power dissipation
400 ps maximum differential skew (5V, 25°C)
3.5 ns maximum propagation delay
Industrial operating temperature range
The DS90C031B accepts TTL/CMOS input levels and
translates them to low voltage (350 mV) differential
output signals. In addition the driver supports 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
11 mW typical.
Pin compatible with DS26C31, MB571 (PECL)
and 41LG (PECL)

Conforms to ANSI/TIA/EIA-644 LVDS standard
Offered in narrow body SOIC package
Fail-safe logic for floating inputs
In addition, the DS90C031B provides power-off high
impedance LVDS outputs. This feature assures
minimal loading effect on the LVDS bus lines when
VCC is not present.
The DS90C031B and companion line receiver
(DS90C032B) provide a new alternative to high
power pseudo-ECL devices for high speed point-to-
point interface applications.
