Truth Table

Inputs					Outputs
S/L	CK INH	CK	SI	A…H	QA	QB	QH	QH
L	X	X	X	a…h	a	b	h	h
H	L	↑	H	X	H	QA_n	QG_n	QG_n
H	L	↑	L	X	L	QA_n	QG_n	QG_n
H	X	H	X	X	No Change
H	H	X	X	X	No Change

Operation: When S/L is LOW, parallel data (A–H) is loaded on the rising clock edge. When S/L is HIGH, serial data shifts through on each rising clock edge. CK INH must be LOW to enable the clock.
