i did a digital clock circuit and need some help in resetting the 74LS90 IC.i know that the 74LS90 can be reset when a HIGH input is connected to pin2 and pin3..but in my clock circuit..i had to connect a AND gate to the pin2 and pin3 as i want the second IC in the following picture to only count from 0 until 5 (the tenth part to count the seconds)...hope someone could help me here...i need help to reset the second IC in the following pic which counts from 0till 5....
The AND gate is not needed. You just need to set the second IC as to mod 6. To do that connect pin 2 to pin 9 and pin 3 to pin 8 and it will count 0 to 5 and reset to zero. As for resetting the IC, you should be able to input the high to pins 2 and 3 even when connected to other pins or gates.
