Additional Details

The 74LCX74MX_NL features a dual D-type flip-flop configuration. Each flip-flop is triggered by the positive edge of the clock (CLK) input. The D input is sampled at the rising edge of the CLK, and the data is transferred to the Q output. The device also includes asynchronous preset (PRE) and clear (CLR) inputs, which allow the flip-flop to be set or reset independently of the clock. The device operates over a wide voltage range (2.0V to 5.5V) and has TTL-compatible inputs, making it easy to interface with other logic families. The outputs can source or sink up to 24mA, providing sufficient drive capability for most applications. The device is available in a SOIC package.
