Four-way flashing light string circuit (10)

It is an eight-pattern four-way flashing light string controller made of S(capacity 061 light screw integrated circuit) .
SC3061 is a product of Hangzhou Tulan Microelectronics Co., Ltd. (http://wWw.siian.com.cn). It
uses CMOS Manufacturing process, with four outputs, single-button triggering for function conversion, simple peripheral circuits, etc. SC3061
is a D IP -8 standard package, and black paste soft packaging products can also be customized according to customer requirements.
    SC30(il adopts a single-button Trigger control
requires few peripheral components and the IU circuit is simple.
The oscillation circuit has been integrated inside the chip, so there is no need for
external oscillation resistor-capacitor components. z (1 is the chip synchronization
signal input terminal, through a high-impedance resistor ruler,
the 50Hz working Frequency signal is introduced to synchronize the internal
oscillation circuit. The chip has preset voltage stabilizing source.
Discharging does not require an external voltage stabilizing circuit. H requires an
R, lowering the current limiting resistor and c. filtering.
11-1,,1 It is the 4-way control signal output terminal, which can directly drive the thyristor WJl-VT1 (Huanzhou.VIC R100-8
type) to make the colored lamp El-E4 flash according to the chip's internal preset/program.
    TG is the working mode selection terminal, built-in There is a pull-up resistor, which controls the flashing mode of the color lamp through low-level triggering
. Each time Sll is pressed, the color lamp can change to a working mode. There are 8 modes that can be converted in sequence. The circuit
will automatically Enter mode J￡1 and press the button once to enter P mode. The 8 modes are grouped as follows:     Mode j1: is the combination mode. In this mode, the lantern works in six modes from mode 2 to mode 17], and the slave mode alternates in sequence. Make a cow.     Mode C 2: For the wave J Ge, move forward and backward. There are two types of light flashing, fast and slow. Press Shaanxi, slow - Shaanxi... to make ten alternately. Each uL and slow state has a certain time interval r, and the state is forward by Change to retreat.     Mode_{: flashing for horse racing. The flashing sequence is E1, E2, E2, F3-E3, F4-E4, El-Fl, E2... There are 4 states from panic to fast, at a certain time interval occur alternately.
