Additional Details

The TC74LCX273F features a positive-edge triggered clock, meaning the data is stored into the flip-flop on the rising edge of the clock signal. The clear input is an active-low input that resets all the flip-flops simultaneously. The device is designed to operate over a wide temperature range. The output drive capability of 24 mA allows it to drive a variety of loads. The device is typically used in applications where high speed, low power, and high density are required.
