CMOS Logic ◆CMOS Logic D-Type Flip Flop ■Applications ◆Operating Voltage Range : 2V ~ 5.5V ●Palmtops : fmax = 170MHz TYP ●Digital Equipment ◆High Speed Operations ◆Low Power Consumption : 1µA (max) ◆MSOP-8B Package ■Description ■Features XC74WL74AASR is D-Type Flip Flop manufactured using silicon gate CMOS processes. The small quiescent current, which is one of the features of the CMOS logic, gives way to high speed operations which enables LS-TTL. With wave forming buffers connected internally, stabilized output can be achieved as the series offers high noise immunity. As the series is integrated into a mini molded, MSOP-8B package, high density mounting is possible.
