Data input. Data is programmed into the 16Bit shift register on the rising CLK edge
8 digit driver lines that sink the current from the common cathode of the display. In shutdown
mode the AS1100 switches the outputs to V
Both GND pins must be connected.
Strobe input. With the rising edge of the LOAD signal the 16 bit of serial data is latched into
the register.
Clock input. The interface is capable to support clock frequencies up to 10MHz. The serial
data is clocked into the internal shift register with the rising edge of the CLK signal. On the
DOUT pin the data is applied with the falling edge of CLK.
Seven segment driver lines including the decimal point. When a segment is turned off the
output is connected to GND.
The current into ISET determines the peak current through the segments and therefore the
brightness.
Positive Supply Voltage (+5V)
Serial data output for cascading drivers. The output is valid after 16.5 clock cycles. The
output is never set to high impedance.
