PIN CONFIGURATIONS
Note: Bottom ground plate must be grounded for proper RF performance.
SERIAL DATA LOAD
Serial data is shifted into the register on the rising edge of clock, MSB first. The state of “OE” will not affect the shifting of
data. The rising edge of the “OE” signal will be the clock for the transfer of shifted data. Latched new data occurs one
prop delay after the rising edge of “OE”. See the Electrical Spec Table for AC parameters.
TRUTH TABLE
Operation: Data on serial input D is clocked into internal registers on the low to high transition of the Clock signal (CK).
The register output is enabled when Output Enable (OE) is in the low state.
