Product specification
74HC/HCT7046A
(1) To obtain optimum VCO performance, C1 must be as small as possible but larger than 100 pF.
(2) Interpolation for various values of R2 can be easily calculated because a constant R2C2 product will produce
almost the same VCO output frequency.
Fig.28 Typical value of frequency offset as a function of C1: R1 = ∞; VVCOIN = 1/2 VCC; INH = GND; Tamb = 25 °C.
