FUNCTION

Parallel Data Input Terminals (with pull-up resistors)

Ground

Parallel Data Input Terminals (with pull-up resistors)

Serial Data Output Terminal

Serial Clock Input Terminal

Chip Enable Input Terminal

Power Supply Terminal (2.7 to 5.5V)

FUNCTIONAL DESCRIPTION

At the falling edge of CE terminal, the status of P0 to P10 terminal is latched and transferred to the shift

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.

When CE terminal is “H”, SO terminal is high impedance.

Note 1) If the 11th falling edge and later are input to CLK terminal while CE is “L”, the 12th and the following data are invalid.
