No.1410–3/4 LB1403N, 1413N, 1423N, 1433N, 1443N · C1, R1 time constant : The response time can be varied by varying the C1, R1 time constant (mainly the C1 value). When the C1, R1 time constant is larger : .................. The response time (attack time and release time) is made slower. When the C1, R1 time constant is smaller : .................. The response time (attack time and release time) is made faster. · Considerations relative to Pd max of the package : Due to the constant current ILED, most of the power consumed by the circuits is consumed within the IC. When lighting the five LEDs continuously for a prolonged length of time, make sure that VCC does not exceed : LB1403N, 1413N, 1443N VCC=9V LB1423N, 1433N VCC=14V When using a higher power supply voltage, insert a resistor in series with the LEDs to restrain the power consumed within the IC package. For LB1403N, 1413N, 1443N : For LB1423N, 1433N Specifications of any and all SANYO products described or contained herein stipulate the performance, characteristics, and functions of the described products in the independent state, and are not guarantees of the performance, characteristics, and functions of the described products as mounted in the customer's products or equipment.
