Data Decode
For up-to-date product info visit our web site at www.marktechopto.com All specifications subject to change.
The TB62709F utilizes two basic modes of operation. In the DECODE MODE, data encoded in
data bits D7~D0 is decoded to display preset characters per table 8. This mode is activated as
illustrated in table 5. With D15~D8 programmed as 21 Hex and D7~D4 as 1 Hex the DECODE
MODE is selected.
In the DIRECT DRIVE MODE the ability to decode data to preset characters for display is
bypassed giving the programmer direct control of the 8 constant current sink outputs. This mode
may be used to drive discrete LEDs or to display characters not included in the character set.
“x” indicates that data is required in this field to execute the function. “-” indicates that data in
this field is not required and not recognized.
This programming step is performed simultaneously with the DIGIT SELECTION decision (table
4) which utilizes D3~D0.The initial state, upon power up, is the DECODE mode.
Table below illustrates the input / output relationship in the DIRECT DRIVE mode. A Logic 1
data state turns the respective output on and a Logic 0 data state turns the respective output off.
