Pin Definition.

Name Symbol Pin Name Pin No. Description

S1,S2    Logic power supply    1,3    connected to VCC

G1,G2   control pins          2,4     active low

D1,D2    output pins        5--8 output line power



 

   In display applications, pins 1, 3 are VDD; pins 2, 4 are low (L) before 56, 78 are output.


actual led display maintenance case: there are two lines are always on, do not exclude is the gate is broken, G1 and D1 conductive.


Example: conventional P10 monochrome cell board has four 4953, one control 4 lines, D1 control 2 lines of the first and the ninth line, D2 control 2 lines of the second and the tenth line.
