MC74AC273DWG Description

The MC74AC273DWG from onsemi is a high-performance 8-bit D-type flip-flop with master reset, designed for surface-mount applications in the 74AC series. Operating within a 2V to 6V supply range, it delivers 175 MHz clock frequency and features positive-edge triggering for reliable data latching. With a max propagation delay of 9ns @ 5V, 50pF, this IC ensures high-speed signal processing while maintaining low power consumption (8 µA quiescent current). Its 24mA output drive capability (both high and low) makes it suitable for driving heavy loads, and its ROHS3 compliance ensures environmental safety. Packaged in a 20-SOIC tube, it is ideal for industrial and commercial applications requiring robust performance.
