For proper operation, ensure that +1.65V ≤ V
+5.5V and +1.1V ≤ V
(V
+ 0.3V) does not damage the device. The speed of the
rise time accelerator circuitry limits the maximum data
rate for the MAX13046E/MAX13047E to 16Mbps.
The MAX13046E/MAX13047E have an internal rise-time
accelerator, allowing operation up to 16Mbps. The rise-
time accelerators are present on both sides of the
device and act to speed up the rise time of the input
and output of the device, regardless of the direction of
the data. The triggering mechanism for these accelera-
tors is both level and edge sensitive. To guarantee
operation of the rise time accelerators the maximum
parasitic capacitance should be less than 200pF on the
I/O lines.
Drive SHDN low to place the MAX13046E/MAX13047E
in shutdown mode and drive SHDN high for normal
operation. Activating the shutdown mode disconnects
the internal 10kΩ pullup resistors on the I/O V

allow for use in a multidrop network. The MAX13046E/
MAX13047E have a diode from each I/O to the corre-
sponding supply rail and GND. Therefore, when in shut-
down mode, do not allow the voltage at I/O V
