I am using 74HCT4046 IC as vco in proteus. At pin 9, i am giving 2.5-3.7V as input and i hv to get square wave pulses as output at pin 4. I hv tried circuits by using datasheets but i am getting triangular pulses of 500kHz.
Does anyone know how to modify the circuit connections so that i get square wave pulses at output ?
Also how to import LMF90 and 565 IC from PSpice to Proteus ?
