SN74AHC273PW

SN74AHC273PW Description

The SN74AHC273PW from Texas Instruments is a high-performance 8-bit D-type flip-flop with a master reset function, designed for surface-mount applications. Operating within a 2V to 5.5V supply range, this device is part of the 74AHC series, offering low power consumption (4 µA quiescent current) and high-speed operation (110 MHz clock frequency). It features positive-edge triggering and delivers balanced output drive (8mA sink/source current), making it suitable for interfacing with both CMOS and TTL logic levels. The 11ns propagation delay at 5V ensures reliable performance in timing-critical applications. Packaged in a 20-pin TSSOP, it is RoHS3 compliant and rated for unlimited moisture sensitivity (MSL 1).
