BIT
NAME
DESCRIPTION
D6
CH1
Channel 1 Write Enable. Set to 1 to update
the control byte for channel 1. Set to 0 to
make no changes to channel 1.
D5
CH2
Channel 2 Write Enable. Set to 1 to update
the control byte for channel 2. Set to 0 to
make no changes to channel 2.
D4
LLEAK
Low-Leakage Select. Set to 1 to put driver,
load, and clamps into low-leakage mode.
Comparators remain active in low-leakage
mode. Set to 0 for normal operation.
D3
TMSEL
Termination Select. Driver termination select
bit. Set to 1 to force the driver output to the
DTV_ voltage (term mode) when RCV_ = 1.
Set to 0 to place the driver into high-
impedance mode (high-Z) when RCV_ = 1.
See Table 1.
D2
SC1
D1
SC0
Driver Slew Rate Select. SC1 and SC0 set the
driver slew rate. See Table 2.
D0
LDCAL
Load Calibrate. Overrides LDEN to enable load.
Set LDCAL to 1 to enable load. Set LDCAL to 0
for normal operation. See Table 4.
Analog control input THR sets the threshold for the
input logic, allowing operation with CMOS logic as low
as 0.9V. Leaving THR unconnected results in a nomi-
nal threshold of 1.25V from an internal reference, pro-
viding compatibility with 2.5V to 3.3V logic.
Temperature Monitor
The MAX9961/MAX9962 supply a temperature output
signal, TEMP, that asserts a nominal output voltage of
3.43V at a die temperature of +70°C (343K). The out-
put voltage increases with temperature at 10mV/°C.
Heat Removal
Under normal circumstances, the MAX9961/MAX9962
require heat removal through the exposed pad by use
of an external heat sink. The exposed pad is electrical-
ly at VEE potential, and must be either connected to
VEE or isolated. The pad is located on the top of the
MAX9961, and on the bottom of the MAX9962.
