MM74C912 6-Digit BCD Display Controller/Driver October 1987 Revised January 1999 MM74C912 6-Digit BCD Display Controller/Driver General Description The MM74C912 display controllers are interface elements, with memory, that drive a 6-digit, 8-segment LED display. The display controllers receive data information through 5 data inputs A, B, C, D and DP, and digit information through 3 address inputs K1, K2 and K3. The input data is written into the register selected by the address information when CHIP ENABLE, (CE), and WRITE ENABLE, (WE), are LOW and is latched when either CE or WE return HIGH. Data hold time is not required. A self-contained internal oscillator sequentially presents the...
