PHILIPS 74HC/HCT374 Octal D-type flip-flop; positive edge-trigger; 3-state handbook
The Philips 74HC/HCT374 is a high-speed Si-gate CMOS device featuring an 8-bit positive, edge-triggered register with common 3-state output enable input. These devices are pin compatible with low power Schottky TTL (LSTTL) and are specified in compliance with JEDEC standard no. 7A. They are designed for bus-oriented applications where the outputs can be placed in a high impedance OFF-state.

Questions answered in these manuals
What is the function of the OE input?
When OE is LOW, the contents of the flip-flops are available at the outputs; when OE is HIGH, the outputs go to the high impedance OFF-state.

What happens to the outputs when the OE pin is HIGH?
The outputs go to the high‑impedance OFF‑state.
Which pins provide the data inputs for the flip‑flops?
Pins 3, 4, 7, 8, 13, 14, 17, and 18 are the D inputs.
