It is ideal for low power and highspeed 3.3V applications; it can be interfaced to 5Vsignal environment for inputs.A signal on the D INPUT is transferred to the QOUTPUT during the positive going transition of theclock pulse.CLR and PR are independent of the clock andaccomplished by a low setting on the appropriateinput.It has same speed performance at 3.3V than 5VAC/ACT family, combined with a lower powerconsumption.All inputs and outputs are equipped withprotection circuits against static discharge, givingthem 2KV ESD immunity and transient excessvoltage.74LCX74LOW VOLTAGE CMOS DUAL D-TYPE FLIP FLOPWITH 5V TOLERANT INPUTSPIN CONNECTION AND IEC LOGIC SYMBOLSORDER CODESPACKAGE TUBE T & RSOP 74LCX74M 74LCX74MTRTSSOP 74LCX74TTRTSSOPSOPAVR347 harman/kardon181
