DILC-16 FPC-16 ORDER CODES PACKAGE FM EM DILC FPC M54HC174D M54HC174K M54HC174D1 M54HC174K1 Information signals applied to D inputs are transferred to the Q output on the positive going edge of the clock pulse. When the CLEAR input is held low, the Q outputs are held low independently of the other inputs. All inputs are equipped with protection circuits against static discharge and transient excess voltage.

Average operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x 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 5/10 M54HC174 TEST CIRCUIT CL = 50pF or equivalent (includes jig and probe capacitance) RT = ZOUT of pulse generator (typically 50Ω) WAVEFORM 1: PROPAGATION DELAY TIME, MINIMUM PULSE WIDTH (CLOCK), SETUP AND HOLD TIME (nD TO CLOCK), CLOCK MAXIMUM FREQUENCY (f=1MHz; 50% duty cycle) 6/10 M54HC174 WAVEFORM 2:PROPAGATION DELAY TIME (nQ TO CLEAR)(f=1MHz; 50% duty cycle) WAVEFORM 3:MINIMUM PULSE WIDTH (CLEAR), MINIMUM REMOVAL TIME (CLEAR TO CLOCK)(f=1MHz; 50% duty cycle) 7/10 M54HC174 DILC-16 MECHANICAL DATA mm. inch DIM.
