CD74HC190: Load Data Inputs at Power-On?

Part Number: CD74HC190


For the CD74HC190, I do not plan to control LOAD with any form of MCU or switch, and would prefer to just tie it to either VCC or GND, but I would like to to load the initial value on the ABCD Data Inputs (hardwired) at power-up. Can this be done, or do I need to trigger the load after the IC has been turned on? My best guess right now is to tie LOAD to VCC when powering up.
