DESCRIPTION
The LVQ273 is a low voltage CMOS OCTAL
D-TYPE FLIP FLOP WITH CLEAR fabricated
with sub-micron silicon gate and double-layer
metal wiring C2MOS technology. It is ideal for low
power and low noise 3.3V applications.

74LVQ273T
Information signals applied to D inputs are
transfered to the Q outputs on the positive going
edge of the clock pulse.
When the CLEAR inputs is held low, the Q
outputs are held low independentely of the other
inputs .
It has better speed performance at 3.3V than 5V
LS-TTL family combined with the true CMOS low
power consumption.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.

1) Skew is defined as the absolute value of the difference between the actual propagation delay for any twooutputs of the same device switching in the
same direction, either HIGH or LOW (tOSLH = |tPLHm - tPLHn|, tOSHL = |tPHLm - tpHLn|)

1) CPD isdefined as the value of the IC’sinternal equivalent capacitance which is calculated fromthe operating current consumption without load. (Referto
Test Circuit).Average operting current can be obtained by the following equation. ICC(opr) = CPD • VCC • fIN + ICC/8(per FlipFlop)
