Features

■

256 discrete brightness steps for easy LED dimming and color mixing

■

two programmable blinking rate between 0.625 sec and 1.6 sec for

CAT9532;0.02sec and 6.4 sec for CAT9552

■

■

drives up to 16 LEDs;any bit that is not used to drive an LED can be used

as a GPIO

■

25mA sink current per bit (max 200mA per device)

■

each port can be individually turned on,off,or programmed to blink

■

during power-up or when a manual reset (hardware reset) is asserted,

all outputs are set to off-mode

■

built in noise filter for SDA/SCL inputs

■

0-400KHz clock frequency

Applications

■

LED dimming

■

LCD backlighting

■

celluar phones

Notes:

1. Available in standard and“green”packages.

2. CAT7311 is pin compatible with the MAX7311.All other products are pin compatible with Philips (replace PCA with CAT to order).
