Hi everyone
I have a monostable 555 circuit that is used to generate an LED lamp test
signal. The signal is a single positive going 5v pulse of about 2 seconds and is generated at power up.
I need a POR signal to intialize a couple of 74HCT74 D flip flops (set Q to 0) and also clear a
74HCT163 chip (set all Q outputs to 0).
Can this same signal be used to reset the FF's and clear the 74HCT163 chip if I invert the output with an 74HCT14 inverter?
I'm thinking I can connect the FF RD pins and the 163 chip MR pin to the inverted signal.
Or do I need to provide a dedicated circuit?
thanks
