74AC273SJX

Overview

The onsemi 74AC273SJX is an octal D-type flip-flop belonging to the AC logic family. It integrates eight edge-triggered D-type flip-flops with individual data inputs and corresponding Q outputs. The device features a common buffered clock input and a buffered asynchronous master reset input, allowing simultaneous loading or clearing of all flip-flops. It operates within a supply voltage range of 2 V to 6 V. The component provides single-ended outputs capable of sourcing and sinking 24 mA. It is housed in a SOP-20 surface-mount package and supports operation across a temperature range of -40°C to +85°C.
