TC74AC273P/F/FW/FT
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74AC273P,TC74AC273F,TC74AC273FW,TC74AC273FT
Octal D-Type Flip Flop with Clear
The TC74AC273 is an advanced high speed CMOS OCTAL
D-TYPE FLIP FLOP fabricated with silicon gate and
double-layer metal wiring C2MOS technology.
It achieves the high speed operation similar to equivalent
Bipolar Schottky TTL while maintaining the CMOS low power
dissipation.
Information signals applied to D inputs are transferred to the
Q output on the positive going edge of the clock pulse.
When the CLR input is held “L”, the Q outputs are at a low
logic level independent of the other inputs.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
Note: xxxFW (JEDEC SOP) is not available in
Japan.

Note:
CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating
current consumption without load.
Average operating current can be obtained by the equation:
ICC (opr) = CPD·VCC·fIN + ICC/8 (per F/F)
And the total CPD when n pcs. of flip flop operate can be gained by the following equation:
CPD (total) = 29 + 11·n
