DILC-20 FPC-20 ORDER CODES PACKAGE FM EM DILC FPC M54HC273D M54HC273K M54HC273D1 M54HC273K1 Information signals applied to D inputs are transferred to the Q outputs on the positive-going edge of the clock pulse. When the CLEAR input is held low, the Q output are in the low logic level independent 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/8 (per FLIP FLOP), and the total CPD when n pcs of FLIP FLOP operate can be gained by the following equations: CPD (total) = 32 + 11 x n 5/10 M54HC273 TEST CIRCUIT CL = 50pF or equivalent (includes jig and probe capacitance) RT = ZOUT of pulse generator (typically 50Ω) WAVEFORM 1: PROPAGATION DELAYS, SETUP AND HOLD TIMES (f=1MHz; 50% duty cycle) 6/10 M54HC273 WAVEFORM 2: PROPAGATION DELAY TIME (f=1MHz; 50% duty cycle) 7/10 M54HC273 DILC-20 MECHANICAL DATA mm. inch DIM.
