XC74WL74AASR

CMOS Logic NCMOS Logic D-Type Flip Flop NOperating Voltage Range : 2V ~ 5.5V NHigh Speed Operations NMSOP-8B Package NLow Power Consumption : 1µA (max) ■Applications GPalmtops : fmax = 170MHz TYP GDigital Equipment ■Description 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. ■Features High Speed Operations : fmax = 170MHz TYP (VCC=5V) Operating Voltage Range : 2V ~ 5.5V Low Power Consumption : 1µA (max) Small Package : MSOP-8B ■Pin Configuration CK D 1 2 3 4 MSOP-8B （TOP VIEW） 8 7 6 5 VCC PR CLR Q GND Q ■Functions INPUT PR L H L H H H CLR H L L H H H CK X X X D X X X H L X OUTPUT Q H L H H L Q0 Q L H H L H Q0 13 H = High Level L = Low Level X = Don't care 913 XC74WL74AASR ■Absolute Maximum Ratings PARAMETER Power Supply Voltage Input Voltage Output Voltage Input Diode Current Output Diode Current Switch Output Current VCC, GND Current Power Dissipation (Ta=25℃) Storage Temperature Note : Voltage is all Ground standardized.
