HANDLING
Inputs and outputs are protected against electrostatic discharges in normal handling. However, to be totally safe, it is
desirable to take normal precautions appropriate to handling integrated circuits.
CHARACTERISTICS
TDA8775 operating at 50 MHz; SLT = 1 and R_L = 37.5 Ω.
V_DDA = V_DDD = 4.5 to 5.5 V; V_SSA and V_SSD shorted together; V_DDA − V_DDD = −0.5 to +0.5 V; T_amb = 0 to +70 °C; typical
values measured at V_DDA = V_DDD = 5 V and T_amb = 25 °C; unless otherwise specified.
