FUNCTIONAL DESCRIPTION
The F803 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 O1 output vary by, at
most, 1 nanosecond. Therefore, the device is ideal for use as
a divide-by-two driver for high-frequency clock signals that
require symmetrical duty cycles. The difference between the
LOW-to-HIGH and HIGH-to-LOW propagation delays for the
O0, O2, and O3 outputs vary by at most 1.5 nanoseconds.
These outputs are very useful as clock drivers for circuits with
less stringent requirements. In addition, the output-to-output
skew is a maximum of 1.5 nanoseconds. Finally, the IOH
specification at 2.5 volts is guaranteed to be at least – 20
milliamps. If their inputs are identical, multiple outputs can be
tied together and the IOH is commensurately increased.

* Normal test conditions for this device are all four outputs switching simultaneously. Two outputs of the 74F803 can be tied together and the
IOH doubles.
1. For conditions such as MIN or MAX, use the appropriate value specified under guaranteed operating ranges.
2. 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 (except for O1) 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.
