Description
The M54/74HCT74 is a high speed CMOS DUAL D TYPE FLOP WITH PRESET AND CLEAR fabricated in silicon gate C2 MOS technology. It has the same high speed performance of LSTTL combined with trueCMOSlow power consumption. Asignal on the DINPUT is transferred to the Q OUTPUTduring the positive going transition of the clock pulse. CLEAR and PRESET are independent of the clock and accomplished by alow on the appropriate input. All inputs are equipped with protection circuits against static discharge and transient excess voltage. This integrated circuit has input and output characteristics that are fully compatible with 54/74 LSTTL logic families. M54/74HCT devices are designed to directly interface HSC2 MOS systems with TTL and NMOS components. They are also plug in replacements for LSTTL devices giving a reduction of power consumption.
