: The LS7538 and LS7539 are CMOS integrated circuits which provide trigger pulses for triac phase control of incandescent lamps.

The circuits are designed to operate with a wide variety of lamp sizes ranging from small table lamps to large floor lamps.

The AGC Loop automatically adjusts Touch Sensitivity to be independent of lamp size.

Touch Sensitivity guaranteed to 600pF Touch Plate Capacitance. Touch Operation independent of line plug polarity. Pin selection of three available Brightness Step Sequences. Minimal external components. AGC Loop stabilizes immediately after Power-Up. Brightness state is Off after AC power applied. Brightness state is unchanged if AC power interrupted for < 0.5 sec. Advanced CMOS design.
