Note 1) At the positive edge of CPS input, SI input status is read into the shift resistor in sequence.

Note 2) All data is set at the positive edge of the 21st pulse. After that, CPS is invalid.

Note 3) While RST is set to "H", neither CPS nor SI is received.

(2) Input Signal Timing

(3) Input Voltage

VIH = 0.7*VCC ~ 3.6 (V)

VIL = -0.2 ~ 0.3*VCC (V)

tSU = th = tWH = tWL > 0.5 µs

tCR = tRH = tRC > 1 µs
