Product Description

General Description
The AC/ACT74 is a dual D-type flip-flop with Asynchronous 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 input 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(Set) sets Q to HIGH level
LOW input to CD(Clear) sets Q to LOW level
Clear and Set are independent of clock
Simultaneous LOW on CDand SDmakes both Q and Q HIGH
Features
■ICCreduced by 50%
■Output source/sink 24 mA
■ACT74 has TTL-compatible inputs
