10-OUTPUT CONTROLLER IC
■ DESCRIPTION
7350 is specially designed for 10
outputs applications. It is mainly used
in car braking system with multi-control
inputs.
Speed is adjusted by external RC
oscillator.
Maximum 10 outputs, the reset pin can
be connected to use fewer outputs.
Directly application in 12VDC circuits，
more convenience and stability。
■ FEATURES
CMOS Fab Technology
Working Voltage：2.0~15VDC
Functions are：
(1) Sequencial Chasing - POWER ON
(2) Steady On
(3) All Flashing
(4) Forward and Backward Chasing
(5) Sequencially Grow
(L1,L1L2, ..,OFF,L1,..)
Outputs can be set to 2-10 outputs
Output is source type (positive) to direct
drive LED or drive by NPN transistor
