Description

The LS74A is an electronic component model that belongs to the flip flops product category. It is a dual D-type positive edge-triggered flip-flop. It utilizes Schottky TTL circuitry that enables it to produce high-speed D-type flip-flops. This model is equipped with individual clear and set inputs, and also complementary Q and Q outputs. Information at input D is transferred to the Q output on the positive-going edge of the clock pulse. When the clock input is at either the HIGH or the LOW level, the D input signal has no effect.
