The HCS374MS utilizes advanced CMOS/SOS technology.
The eight flip-flops enter data into their registers on the LOW-to-HIGH transition of the clock (CP).
The output enable (OE) controls the three-state outputs and is independent of the register operation.
Yes, these devices are sensitive to electrostatic discharge and require proper IC handling procedures.
