M54HCT174 M74HCT174 HEX D-TYPE FLIP FLOP WITH CLEAR . . . . . . . HIGH SPEED fMAX = 56 MHz (TYP.) AT VCC = 5 V LOW POWER DISSIPATION ICC = 4 µA (MAX.) AT TA = 25 °C COMPATIBLE WITH TTL OUTPUTS VIH = 2V (MIN.) VIL = 0.8V (MAX) OUTPUT DRIVE CAPABILITY 10 LSTTL LOADS SYMMETRICAL OUTPUT IMPEDANCE IOH = IOL = 4 mA (MIN.) BALANCED PROPAGATION DELAYS tPLH = tPHL PIN AND FUNCTION COMPATIBLE WITH 54/74LS174 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.

(Refer to Test Circuit). Average operting current can be obtained by the following equation. ICC(opr) = CPD •VCC •fIN + ICC/6 (per FLIP/FLOP) And the total CPD when N pcs of FLIP FLOP operate can be gained by the following equation: CPD (total)= 38 + 15 x n 5/11 M54/M74HCT174 SWITCHING CHARACTERISTICS TEST WAVEFORM TEST CIRCUIT ICC (Opr.) 6/11 M54/M74HCT174 Plastic DIP16 (0.25) MECHANICAL DATA mm DIM.
