FUNCTION
Serial Clock Input. Apply an external clock to SCLK to facilitate communication through the serial
bus. SCLK may idle high or low.
Serial Data Output. DOUT presents serial data in response to register queries. Data shifts out on
the falling edge of SCLK. DOUT goes high impedance when CS is high.
Serial Data Input. Data present at DIN is shifted into the internal registers in response to a rising
edge at SCLK when CS is low.
Active-Low Chip-Select Input. Forcing CS low activates the serial interface. (See Table 8.)

LED-Display Segment-Driver Supply. Connect to a +2.7V to +5.25V supply. Bypass with a 0.1μF
capacitor to LEDG.

Active-High LED Enable. The MAX1366/MAX1368 display driver turns off when LED_EN is low.
The MAX1366/MAX1368 LED-display driver turns on when LED_EN is high.
-2.5V Charge-Pump Voltage Output. Connect a 0.1μF capacitor to GND.
Low-Battery-Voltage Monitor. When the LOWBATT input voltage is lower than 2.048V, the
LOWBATT bit in the status register is set to one.
Negative Reference Voltage Input. For internal reference operation, connect REF- to GND. For
external reference operation, bypass REF- to GND with a 0.1μF capacitor and
set V REF- from -2.2V to +2.2V (V REF+ > V REF- ).
Positive Reference Voltage Input. For internal reference operation, connect a 4.7μF capacitor from
REF+ to GND. For external reference operation, bypass REF+ to GND with a 0.1μF capacitor and
set V REF+ from -2.2V to +2.2V, provided that V REF+ > V REF- .
