5 / 7 page 2. Individual pins and their operations As shown above, when input level is raised and the pin 2 voltage reaches the VTH-H level of the comparator, pins 5 and 7 turn over. (VIN = −45 dBm). . pin 5 is for driving plungers. When it is on the ‘‘L’’ side, pin 5 turns on and can draw current up to 50 mA maximum. . Pin 6 is a diode that prevents reverse voltages induced when the plunger is turned off from on. . Pin 7 functions in phase with pin 5 and can drive external transistors (such as for MUTE). 3. Time delays and obtaining CRs When input signals that have been applied at a level not less than −45 dBm are removed, discharging occurs through the CR connected at pin 2, lowering pin 2 potential. A time delay is provided before the hysteresis comparator turns over. E1 E0 =− t e τ E0 : Initial voltage E1 : Threshold voltage τ : Time constant Accordingly, t=− τIn E1 E0 E1/E0, within the IC, is 0.26. A desired time delay is obtained by an appropriate choice of τ (τ =C 3R1). Therefore, the time delay is obtained by the following formula: t = 1.34 × C 3R1 (sec) We recommend 150 k Ω to 500 kΩ for R when determining CR. 4. IC usage notes . Maximum ratings When maximum ratings are surpassed, destruction or deterioration may result. . Interpin short circuits and reverse insertions These cause destruction or deterioration of the IC: be careful when mounting on circuit board. . Voltage applied to pin 7 should never exceed pin 8 voltage. . The current flowing into pin 7 is to be 0.5 mA maximum. Input signal level, VIN − dBm LA2000M No.4158-5/7 |
