Function
Reference terminal for control logic.
Serial-data input to the shift-register.
Clock input terminal for data shift on rising edge.
Data strobe input terminal; serial data is latched with high-level input.
The eight current-sinking output ter mi nals.
When (active) low, the output drivers are enabled; when high, all output driv-
ers are turned OFF (blanked).
CMOS serial-data output to the following shift-register.
An external resistor at this terminal establishes the output current for all sink
drivers.
