) BALANCED PROPAGATION DELAYS tPLH = tPHL WIDE OPERATING VOLTAGE RANGE VCC (OPR) = 2 V TO 6 V PIN AND FUNCTION COMPATIBLE WITH 54/74LS109 B1R (Plastic Package) F1R (Ceramic Package) M1R (Micro Package) C1R (Chip Carrier) ORDER CODES : M54HC109F1R M74HC109M1R M74HC109B1R M74HC109C1R DESCRIPTION The M54/74HC109 is a high speed CMOS DUAL JK FLIP-FLOP WITH PRESET AND CLEAR fabri2 cated in silicon gate C MOS technology.
It has the same high speed performance of LSTTL combined with true CMOS low power consumption.
In accordance with the logic level on the J and K input is device changes state on positive going transitions of the clock pulse.
CLEAR and PRESET are independent...
