The MC74F1803 is a high–speed, low–power, quad D–type flip–flop
featuring separate D–type inputs and inverting outputs with closely matched
propagation delays. With a buffered clock (CP) input that is common to all
flip–flops, the MC74F1803 is useful in high–frequency systems as a clock
driver, providing multiple outputs that are synchronous. Because of the
matched propagation delays, the duty cycles of the output waveforms in a
clock driver application are symmetrical within 2.0 nanoseconds.

MC74F1803
FUNCTIONAL DESCRIPTION
The MC74F1803 consists of four positive edge–triggered
flip–flops with individual D–type inputs and inverting
outputs. The buffered clock is common to all flip–flops
and the following specifications allow for outputs switching
simultaneously. The four flip–flops store the state of their
individual D inputs that meet the setup and hold time
requirements on the LOW–to–HIGH Clock (CP) transition.
The maximum frequency of the clock input is
70 megahertz and the LOW–to–HIGH and HIGH–to–LOW
propagation delays of the On output vary by at most,
2.0 nanoseconds. Therefore, the device is ideal for use as
a divide–by–two driver for high–frequency clock signals
that require symmetrical duty cycles. In addition, the
output–to–output skew is a maximum of 2.0 nanoseconds.
Finally, the IOH specification at 2.5 volts is guaranteed to
be at least –20 milli–amps. If their inputs are identical,
multiple outputs can be tied together and the IOH is
commensurately increased.

1. For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions for the applicable device
type.
2. Normal test conditions for this device are all four outputs switching simultaneously. Two outputs of the MC74F1803 can be tied together and
the IOH doubles.
3. Not more than one output should be shorted at a time, nor for more than 1 second.

1. The test conditions used are all four outputs switching simultaneously. The AC characteristics described above are also guaranteed when two
outputs are tied together.
2. Where tp On and tp Om are the actual propagation delays (any combination of high or low) for two separate outputs from a given high transition
of CP.
3. For a given set of conditions (i.e., capacitive load, temperature, VCC, and number of outputs switching simultaneously) the variation from device
to device is guaranteed to be less than or equal to the maximum.
