When LOAD goes high, the con- tents of 8-bit serial Shift Register will be decoded. 3 NP No pin 4 NP No pin 5 NP No pin 6 NP No pin 7 NP No pin 8 NP No pin 9 NP No pin 10 NP No pin 11 NP No pin 12 NP No pin 13 RST Asynchronous input, when low will clear the Multiplex Counter, User RAM and Data Register. Control Word Register is set to 100% brightness and the Address Register is set to select Digit 0. The display is blanked. 14 GND Power supply ground 15 CLK I/O Outputs master clock or inputs external clock. 16 CLKSEL H=internal clock, L=external clock 17 NP No pin 18 NC No connection 19 VCC Power supply 20 NP No pin 21 NP No pin 22 NP No pin 23 NP No pin 24 NP No pin 25 NP No pin 26 NP No pin 27 DATA Serial data input 28 GND Power supply ground |
