Description

The HD74LS374, 8-bit register features totem-pole three-state outputs designed specifically for driving highlycapacitive or relatively low-impedance loads. The high-impedance third state and increased high-logic-level drive provide this register with the capability of being connected directly to and driving the bus lines in a bus-organized system without need for interface or pull-up components. They are particularly attractive for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. The eight flip-flops are edge-triggered D-type flipflops. On the positive transition the clock, the Q outputs will be set to the logic states that ware setup at the D inputs.
