Single/Dual LVDS Line Receivers with
鈥淚n-Path鈥?Fail-Safe
General Description
The MAX9171/MAX9172 single/dual low-voltage differential
signaling (LVDS) receivers are designed for high-speed
applications requiring minimum power consumption,
space, and noise. Both devices support switching rates
exceeding 500Mbps while operating from a single 3.3V
supply.
The MAX9171 is a single LVDS receiver and the
MAX9172 is a dual LVDS receiver. Both devices con-
form to the ANSI TIA/EIA-644 LVDS standard and con-
vert LVDS to LVTTL/LVCMOS-compatible outputs. A
fail-safe feature sets the outputs high when the inputs
are undriven and open, terminated, or shorted. The
MAX9171/MAX9172 are available in 8-pin SO packages
and space-saving thin QFN and SOT23 packages.
For lower skew devices, refer to the MAX9111/ MAX9113
data sheet.
