MICROCIRCUIT DATA SHEET
CN54F74-X REV 0A0
Original Creation Date: 06/25/97
Last Update Date: 07/08/97
Last Major Revision Date: 06/25/97
DUAL D-TYPE POSITIVE EDGE-TRIGGERED FLIP-FLOP
General Description
The F74 is a dual D-type flip-flop with Direct Clear and Set inputs and complementary
(Q/Q) outputs. Information at the input is transferred to the outputs on the positive
edge of the clock pulse. Clock triggering occurs at a voltage level of the clock pulse
and is not directly related to the transition time of the positive-going pulse. After the
Clock Pulse Input threshold voltage has been passed, the Data inputs is locked out and
information present will not be transferred to the outputs until the next rising edge of
the Clock Pulse input.
Asynchronous Inputs:
LOW Input to Sd sets Q to HIGH level
LOW Input to Cd sets Q to LOW level
Clear and Set are Independent of clock
Simultaneous LOW on Cd and Sd makes both Q and Q HIGH
