Description
/LBLK = L: All output = L
/HBLK = L: All output = H
Latch operation performed at the falling edge.
HZ = H: All output set to the high-impedance state
/CLR = L: All shift register data cleared to the low level
The A1 to A3 (6) are Data input pins. The data shift direction is switched
inside the R,/L pin.
SDS = H: Shift operation is executed at the rising and falling edges
SDS = L: Shift operation is executed at the rising edge
The shift direction control pin of shift register. The shift directions of the
shift register are as follows.
R,/L = H (right shift):
SR1: A1 → S1...S190 (SR2 to SR6 also shift in the same direction.)
R,/L = L (left shift):
SR1: A1 → S190...S1 (SR2 to SR6 also shift in the same direction.)
Refer to 5. INTERNAL REGISTER.
IBS1 = H, IBS2 = H: 6-bit (3-bit + 3-bit) input, Length of shift register: 32-bit
IBS1 = H, IBS2 = L: 6-bit input, Length of shift register: 32-bit
IBS1 = L, IBS2 = H: 3-bit input, Length of shift register: 64-bit
IBS1 = L, IBS2 = L: 4-bit input, Length of shift register: 48-bit
The DET is N-ch open-drain output. Low level is output (N-ch transistor:
ON) via temperature detection.
SDS = H: Shift operation is executed at the rising and falling edges of CLK
(double edge)
SDS = L: Shift operation is executed at the rising edge of CLK (single edge)

Caution In 3-bit and 4-bit input mode, unused input pins must be held at the low level or high level.
