General Description
These CMOS counters consist of a 4-digit counter an internal output latch NPN output sourcing drivers for a 7-segment display and an internal multiplexing circuitry with four multiplexing outputs The multiplexing circuit has its own free-running oscillator and requires no external clock The counters
Key Features
- Y Y Y Y Wide supply voltage range Guaranteed noise margin High noise immunity High segment sourcing current Internal multiplexing circuitry 3V to 6V 1V 0 45 VCC (typ ) 40 mA VCC b 1 6V VCC e 5V Y Design Considerations Segment resistors are desirable to minimize power dissipation and chip heating The DS75492 serves as a good digit driver when it is desired to drive bright displays When using this driver with a 5V supply at room temperature the display can be driven without segment resistors t.
