description/ordering information

The ’HC74 devices contain two independent D-type

positive-edge-triggered flip-flops. A low level at the preset (PRE)

or clear (CLR) inputs sets or resets the outputs,

regardless of the levels of the other inputs.

When PRE and CLR are inactive (high),

data at the data (D) input meeting the setup time requirements

are transferred to the outputs

on the positive-going edge of the clock (CLK) pulse.

Clock triggering occurs at a voltage level

and is not directly related to the rise time of CLK.

Following the hold-time interval, data

at the D input can be changed

without affecting the levels at the outputs.

PARAMETER MEASUREMENT INFORMATION

NOTES:

A. CL includes probe and test-fixture capacitance.

B. Phase relationships between waveforms were chosen arbitrarily. All input pulses are supplied by generators having the following characteristics: PRR ≤ 1 MHz, ZO = 50 Ω, tr = 6 ns, tf = 6 ns.

C. For clock inputs, fmax is measured when the input duty cycle is 50%.

D. The outputs are measured one at a time with one input transition per measurement. E. tPLH and tPHL are the same as tpd.
