The SN74AS374 is an octal D-type edge-triggered flip-flop featuring 3-state outputs, designed for driving high-capacitance or low-impedance loads. It allows for full parallel access for loading and includes buffered control inputs. The device operates on the positive transition of the clock (CLK) input, setting the Q outputs to the logic levels present at the data (D) inputs. A buffered output-enable (OE) input controls the outputs, allowing them to be placed in a high-impedance state, which is beneficial for bus driving applications. This flip-flop is characterized for operation from 0¬8C to 70¬8C and supports a supply voltage range of 4.5V to 5.5V. It has a maximum clock frequency of 35 MHz and provides reliable performance with specified setup and hold times. The SN74AS374 is suitable for applications such as buffer registers, I/O ports, and bidirectional bus drivers, making it a versatile choice for digital circuit designs.
