PACKAGE: DIL28S
DESCRIPTION
The DMX710 is an DMX512 transmitter with digital inputs. The values of the output
signal are 0 or 255 in digital mode and 0 – 255 in analoge mode, dependent on the
input signal. With the BLACKOUT input it is possible to set all DMX output channels
to 0.
To combine some DMX710 chips, connect the DMX output with the DTC input (DMX
transmitter chain) from the next chip. More informations about the DTC you can find
in the separate document.

RESET
Reset input. A low level on this pin for more then 50ns will
generate a reset, even if the clock is not running. Shorter pulses
are not guaranteed to generate a reset
DTC-SIGNAL
Input for the DMX Transmitter Chain (DTC). If not used, this pin
must connect to GND.

This example illustrates how to use the DMX710 with a 8MHz crystal. The value of
the capacitors should be in the range of 12-33pF.
Digital And Analog Input Configuration

DIGITAL IN
ANALOG IN
Some of the pins of the DMX710 can be used as digital or analog inputs. In the digital
mode you have to connect a switch to GND. The analoge mode permit a signal from
GND to VCC.

The DMX710 is cascadeable, as the DMX exit is connected with the DTC entrance of
the next component. The last DMX exit goes to a line driver. It is possible to use one
oszillator for all DMX710.
