7448 IC DATASHEET PDF

One single IC can be used to count form zero 0 to nine 9 directly on a Common Cathode type 7-segment display. The count can be increased by simply giving a high clock pulse; also more than one digit can be created by cascading more than one CD IC. So if you have a 7-segment CC display on which you have to display numbers that are being counted based on some condition then this IC will be a perfect choice. We have 7 output pins naming from Out A to Out G which is directly connected to the 7-segment display.

One single IC can be used to count form zero 0 to nine 9 directly on a Common Cathode type 7-segment display. The count can be increased by simply giving a high clock pulse; also more than one digit can be created by cascading more than one CD IC. So if you have a 7-segment CC display on which you have to display numbers that are being counted based on some condition then this IC will be a perfect choice. We have 7 output pins naming from Out A to Out G which is directly connected to the 7-segment display.

The 7-segment pins will increment the count by one number each time when the clock pin pin 1 is made high. They simply have to generate a pulse of low voltage 0V and high voltage 5V.

In the circuit below I have used a clock source of 1Hz to increment the count. The Reset pin pin 15 is used to reset the count back to zero when made high. There are three other output pins pin 5,4,14 which will be used only when the IC needs to be cascaded.

This small pulse can be used to drive the clock pin of a cascaded IC to display more than one digit. Used in 7-segment counter projects Can be used to count people or objects crossing a point Has capability to display a wide range of numbers from 0 - Used in project where Microcontrollers should be avoided 2D Model of CD PDIP Component Datasheet.

Gardabar A PWM pulse-width modulated signal can be applied to this pin to provided varying brightnesses to the LED datsheet being driven, allowing user control of LED dimming for applications such as power saving by decreasing the brightness during times of low ambient light.
