DESCRIPTION The M54/74HCT174 is a high speed CMOS HEX DTYPE FLIP-FLOP WITH CLEAR fabricated in silicon gate C2MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low power consumption. Information signals applied to D inputs are transfered to the Q output on thepositive going edge of the clock pulse. When the CLEAR input is held low, the Q outputs are held low independently of the other inputs. 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 HSC2MOS systems with TTL and NMOS components. They are also plug in replacements for LSTTL devices giving a reduction of power consumption. All inputs are equipped with protection circuits against static discharge and transient excess voltage. INPUT AND OUTPUT EQUIVALENT CIRCUIT
