1. Forward, reverse select switch
(1) Threshold voltage
Pin(3) is coupled to the base of Q1 (PNP-Tr) as shown in Fig.1.
Threshold voltage (pin(3)) = 0.7V
(2) The recommended forward, reverse
select circuit is shown in Fig.2.
TA2025P / F
(3) I3 (in Fig.1)
I3 = 12µA (max., Ta = 25°C)
2. Equalizer control switch
Pin(15) is coupled to the base of Q2 (PNP-Tr) as shown in Fig.3.
The emitter potential of Q2 is 3.9V (DC).
Threshold voltage (pin(15)) = 2.8V
3. C2 / C3 / C4 / C5
Capacitor C2~C5 may be required for preventing a instability caused
by the pattern layout or interference of external high frequency signal.
Maximum Ratings (Ta = 25°C)
(Note) Derated above Ta = 25°C in the proportion of 6mW / °C for TA2025P and of 2.8mW / °C for TA2025F.
