Dot matrix format Pin Function Definition 1 SDCLK Loads data into the 8-bit serial data register on a low to high transition. 2 LOAD Low input enables data clocking into 8-bit serial shift register. When LOAD goes high, the contents of 8-bit serial Shift Register will be decoded. 3 NC No connection 4 NC No connection 5 NC No connection 6VCC Power supply/heat sink 7 NP No pin 8 NP No pin 9VCC Power supply/heat sink 10 NC No connection 11 NC No connection 12 NC No connection 13 RST Asynchronous input, when low will clear the Multi- plex 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 NC No connection 18 NC No connection 19 VCC Power supply/heat sink 20 VCC Power supply/heat sink 21 NP No pin 22 NP No pin 23 VCC Power supply/heat sink 24 NC No connection 25 NC No connection 26 NC No connection 27 DATA Serial data input 28 GND Power supply ground 0.100 (2.54) 0.033 (0.84) typ. 0.011 (0.28) typ. 0.022 (0.56) typ. 0.145 (3.68) R0 R1 R2 R3 R4 C0 C1 C2 C3 C4 Dimensions in inches (mm) TOLERANCE : .XXX= ±.010 (.25) |
