The MC54HC273J is a high-speed CMOS octal D-type flip-flop with clear, manufactured by Freescale Semiconductor (now NXP). This device contains eight independent D-type flip-flops with individual D inputs and Q outputs, and a common clear (CLR) input that resets all flip-flops simultaneously. It is part of the HC (High-speed CMOS) logic family, offering high speed and low power consumption.

Additional Details

The MC54HC273J is typically packaged in a 20-pin DIP (Dual In-line Package). The clock input is edge-triggered, and data is transferred from the D input to the Q output on the rising edge of the clock. The propagation delay from clock to output is typically in the nanosecond range. The device is designed for a wide range of operating temperatures.
