74ABT16374CMTD Description

The 74ABT16374CMTD from onsemi is a high-performance dual 8-bit D-type flip-flop designed for applications requiring robust data storage and signal integrity. Operating within a 4.5V to 5.5V supply range, this device features positive-edge triggering and delivers a clock frequency of 150 MHz, making it suitable for high-speed digital systems. With a max propagation delay of 6.2ns @ 5V, 50pF, it ensures efficient data transfer while minimizing latency. The 74ABT series is known for its low power consumption (2 mA quiescent current) and high drive capability (32mA output high, 64mA output low), enabling reliable performance in demanding environments. Packaged in a 48-pin TSSOP tube, this obsolete but still relevant IC remains a viable choice for legacy designs.
