3 Description

This device contains two independent D-type

negative-edge-triggered flip-flops. All inputs include

Schmitt-triggers, allowing for slow or noisy input

signals. A low level at the preset (PRE) input sets the

output high. A low level at the clear (CLR) input

resets the output low. Preset and clear functions are

asynchronous and not dependent on the levels of the

other inputs. When PRE and CLR are inactive (high),

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

requirements is transferred to the outputs (Q, Q) on

the negative-going edge of the clock (CLK) pulse.

Following the hold-time interval, data at the data (D)

input can be changed without affecting the levels at

the outputs (Q, Q).
