ON DELAYS tPLH = tPHL DE OPERATING VOLTAGE RANGE VCC (OPR) = 2 V TO 6 V N AND FUNCTION COMPATIBLE WITH 54/74LS273 B1R (Plastic Package) F1R (Ceramic Package) M1R (Micro Package) C1R (Chip Carrier) ORDER CODES : M54HC273F1R M74HC273M1R M74HC273B1R M74HC273C1R The M54/74HC273 is a high speed CMOS OCTAL D-TYPE 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 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.

(Refer to Test Circuit). Average operting current can be obtained by the following equation. ICC(opr) = CPD *VCC *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 5/11 M54/M74HC273 SWITCHING CHARACTERISTICS TEST WAVEFORM CLEAR = "H" DN = "H" TEST CIRCUIT ICC (Opr.) 6/11 M54/M74HC273 Plastic DIP20 (0.25) MECHANICAL DATA mm MIN. a1 B b b1 D E e e3 F I L Z 3.3 1.34 8.5 2.54 22.86 7.1 3.93 0.130 0.053 0.254 1.39 0.45 0.25 25.4 0.335 0.100 0.900 0.280 0.155 1.65 TYP.
