TERMINAL DESCRIPTION
FUNCTIONAL DESCRIPTION
register. At the mean time, the P0 data is output from SO terminal. While CE terminal is “L”, the data from
P1 to P10 in the shift register are synchronized with the falling edge of CLK terminal and output from SO
terminal.
P0~P10
No.
At the falling edge of CE terminal, the status of P0 to P10 terminal is latched and transferred to the shift
When CE terminal is “H”, SO terminal is high impedance.
