Multi-Level Dimmer…. (16 Pins)
	LS7315, LS7315-SW Last Update: 01/27/03
	Pushbutton input controls
	Up to 10 selectable intensity (power) levels
	A selected intensity level input becomes an output that can drive a LED to indicate the selected intensity
	Applications include wall switch (AC Hot) and plug-in (AC Hot and Neutral) dimmer configurations

Multi-Level Dimmer…. (14 Pins)
	LS7317, LS7317-S Last Update: 01/26/09
	Pushbutton input controls
	Up to 5 selectable intensity (power) levels
	A selected intensity level input becomes an output that can drive a LED to indicate the selected intensity
	Controls high-voltage lamps and electronic-transformer coupled low-voltage lamps via a triac interface
	Applications include wall switch (AC Hot) and plug-in (AC Hot and Neutral) dimmer configurations

Light Dimmer with Up and Down Controls…. (8 Pins)
	LS7535, LS7535-S; LS7535FT, LS7535FT-S Last Update: 11/11/09
	Touch or pushbutton UP and DOWN input controls
	Momentary UP/DOWN input activation cause ramping to MEMORY ON/OFF states
	Prolonged UP/DOWN input activation cause variable dimming operation towards MAX/MIN Brightness Levels
	DOZE input for external control of DIM-TO-OFF time
	LS7535 has "soft" Turn-On/Off; LS7535FT has instant Turn-On/Off

AGC Touch Control Step Dimmer…. (8 Pins)
	LS7538, LS7538-S; LS7539, LS7539-S Last Update: 01/27/03 LS7541, LS7541-S NEW! Last Update: 03/23/07
	Touch Sensitivity is independent of Touch Plate Size and Line-Plug Polarity
	Pin selection of three available Brightness Step Sequences
	LS7539 and LS7541 are functionally equivalent
	Pushbutton control can be used instead of 'Touch'.
	Applications include Wall Switch step dimmers and Touch Control step dimmers for small table lamps to large floor lamps.

AGC Touch Control Light Switch with Soft-Off …. (8 Pins)
	LS7540, LS7540-S NEW! Last Update: 11/06/07
	Touch Sensitivity is independent of Touch Plate Size and Line-Plug Polarity
	If Off, a 'Touch' produces Max Intensity (On) instantaneously
	If On, a 'Touch' initiates intensity ramp-down (Soft-Off). Max intensity to Off ramp-down time is programmable by an external RC. The Soft-Off feature provides light for the User to exit the room. Ramp-down time = 0 if no RC is connected.
	Application of a 'Touch' during ramp-down causes the ramp-down to stop. Once stopped, a 'Touch' causes the ramp-down to Off to resume. Stopping and starting the ramp-down can be repeated as often as desired thus giving the User full control in setting the light intensity.
	Pushbutton control can be used instead of 'Touch'.
	Applications include Wall Switches and Touch Control modules for small table lamps to large floor lamps

Touch Control Halogen Light Dimmer …. (8 Pins)
	LS7631, LS7631-S; LS7632, LS7632-S Last Update: 12/05/05
	Touch or pushbutton input control
	Controls high-voltage lamps and transformer-coupled low-voltage halogen lamps. Magnetic transformers and many electronic transformers.
	Controls Fluorescents and CFLs via dimming ballasts
	Direct replacement for P/N SLB0587
	Soft-turn on
	Automatic safety cutout
	Mode input selects LS7231, LS7232 or LS7233 type operation
	LS7631 - dimming cycles through Maximum and Minimum
	LS7632 - dimming stops at Maximum and Minimum
