Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook (“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test report and estimated failure rate, etc). 2 Note 1: When mounted on the glass epoxy of 2.5 cm × 0.4 t Pin Assignment VGCA GND OUT OUT (1) (2) 5 7 6 8 4018F 1 2 3 4 VCC NC IN (1)IN (2) 1 2007-11-01 TA4018F Electrical Characteristics (Ta = 25°C, VCC = 5 V, Zg = Zl = 50 Ω) Characteristics Circuit current Input return loss Insertion gain (1) Insertion gain (2) Symbol Test Circuit Min Typ.
