74ACT273SCX

The 74ACT273SCX is an octal D-type flip-flop IC manufactured by ON Semiconductor. This device contains eight edge-triggered D-type flip-flops, each with individual D-type inputs and Q outputs. A common buffered Clock (CP) and Master Reset (MR) input allow for simultaneous loading and resetting of all flip-flops. The register is fully edge-triggered, transferring the state of each D-type input to its corresponding Q output on the LOW-to-HIGH clock transition.

Key electrical characteristics include an operating voltage range of 4.5V to 5.5V, a maximum clock frequency of 189 MHz, and a maximum propagation delay of 8.5ns at 5V and 50pF. The device draws a quiescent current of 40 µA and has an input capacitance of 4.5 pF. The 74ACT273SCX also features TTL-compatible inputs and outputs that can source or sink 24mA. The operating temperature range is -40°C to 85°C (TA).

This flip-flop is ideal for applications requiring a buffer for microprocessors or memory where true outputs are needed and the clock and master reset are common to all storage elements. The device is supplied in a 20-SOIC (0.295", 7.50mm Width) surface mount package.
