Q signal input pin. The input
impedance is 500 kΩ or more.
(Only DC signals can be normally
input at the VCC/2 DC Bias.)
Q signal input pin. The input
impedance is 500kΩ or more.
(Signals of up to 1 Vp-p can be input
at the VCC/2 DC Bias.)
10 IF OUTPUT
∗1.4
IF output pin. (An output impedance
of 50 Ω is provided by the emitter
10
follower.)
