Description
PC = L: All driver output invert
BLK = H: All output = H or L
Automatically executes latch by setting High at rising edge
of the clock
When R/L = H,
A1 to A4: Input B1 to B4: Output
When R/L = L,
A1 to A4: Output B1 to B4: Input
Shift executed on fall
Right shift mode when R/L = H
SR1: A1 → S1 ··· S61 → B1 (Same direction for SR2·SR4)
Left shift mode when R/L = L
SR1: B1 → S61 ··· S1 → A1 (Same direction for SR2·SR4)
130 V, 40 mA MAX.
5 V ±10%
30 to 130 V
Connect to system GND
Connect to system GND
Non-connection
Ensure that pin 40 is left open.
