FIN1532
5V LVDS 4-Bit High Speed Differential Receiver
General Description
This quad receiver is designed for high speed intercon-
nects utilizing Low Voltage Differential Signaling (LVDS)
technology. The receiver translates LVDS levels, with a typ-
ical differential input threshold of 100 mV, to LVTTL signal
levels. LVDS provides low EMI at ultra low power dissipa-
tion even at high frequencies. This device is ideal for high
speed transfer of clock and data.
The FIN1532 can be paired with its companion driver, the
FIN1531, or any other LVDS driver.

s Low power dissipation
s Power-Off protection for inputs and outputs
s Fail safe protection for open-circuit, shorted and termi-
nated receiver inputs
s Meets or exceeds the TIA/EIA-644 LVDS standard
s Pin compatible with equivalent RS-422
and PECL devices
s 16-Lead SOIC and TSSOP packages save space
