Functional Description
Character Font
Segment Identification
The MM74C912 display controller is manufactured using
metal gate CMOS technology. A single 5V 74 series TTL
supply can be used for power and should be bypassed at
the V
CC
pin.
All inputs are TTL compatible; the segment outputs drive
the LED display directly through current limiting resistors.
The digit outputs are designed to directly drive the base of
a grounded emitter digit transistor without the need of a
Darlington configuration.
As seen in the block diagram, these display controllers
contain six 5-bit registers; any one of which may be ran-
domly written. The internal multiplexer scans the registers
and refreshes the display. This combination of write only
memory and self-scan display makes the display controller
a “refreshing experience” for an over-burdened micropro-
cessor.
