Octal D-type Edge-triggered Flip-Flips (with three-state outputs)

The HD74LS374, 8-bit registers feature totem-pole three-state outputs designed specifically for driving highly-capacitive or relatively low=impedance loads. The highly-impedance third state and increased high-logic-level drive porvide this register with the capability of being connected directly to and driving the bus lines in a bus-organized system without neeed for interface or pull-up components. They are paricularly attractive for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.
