TIMING DIAGRAMS

TIMING DEFINITIONS

SYMBOL

PARAMETER

tCKH

Width of input clock pulse.

tCKL

Interval between clock pulses.

tCKP

Clock period.

tPRH

Width of preset input pulse.

tIS1

Required delay between

beginning of valid input and

positive transition of clock.

tIS2

Required delay between

beginning of valid input forced

at flip-flop output pins, and

positive transition of clock.

tIH1

Required delay between

positive transition of clock and

end of valid input data.

tIH2

Required delay between

positive transition of clock and

end of valid input data forced

at flip-flop output pins.

tCKO

Delay between positive

transition of clock and when

outputs become valid (with

OE Low).

tOE1

Delay between beginning of

Output Enable Low and when

outputs become valid.

tOD1

Delay between beginning of

Output Enable High and

when outputs are in the

OFF-State.

tPPR

Delay between VCC (after

power-on) and when flip-flop

outputs become preset at “1”

(internal Q outputs at “0”).

tPD

Propagation delay between

combinational inputs and

outputs.

tOE2

Delay between predefined

Output Enable High, and

when combinational outputs

become valid.

tOD2

Delay between predefined

Output Enable Low and when

combinational outputs are in

the OFF-State.

tPRO

Delay between positive

transition of predefined

Preset/Reset input, and

when flip-flop outputs become

valid.
