The 74HC/HCT374 is a high-speed Si-gate CMOS device and is pin compatible with low power Schottky TTL (LSTTL).
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.

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.
The device features 3-state non-inverting outputs.
Yes, the 374 is functionally identical to the 534, but it has non-inverting outputs.
