SN74HC273NSR

The SN74HC273NSR from Texas Instruments is an octal D-type flip-flop with a clear input. This device is designed for positive-edge triggering, transferring data from the D inputs to the Q outputs upon the positive-going edge of the clock pulse. It features a wide operating voltage range from 2V to 6V and can operate at clock frequencies up to 60 MHz.

Key electrical characteristics include a typical propagation delay of 12 ns and an output drive of ±4 mA at 5V. The device consumes low power, with a maximum supply current of 80 µA and a low input current of 1 µA maximum. It contains eight flip-flops with single-rail outputs and a direct clear input.

This component is supplied in a 20-SOIC surface mount package, making it suitable for various digital logic applications such as buffer or storage registers, shift registers, and pattern generators. The operating temperature range is -40°C to 85°C (TA).

Applications include buffer or storage registers, shift registers, and pattern generators. The SN74HC273 devices are positive-edge-triggered D-type flip-flops with a direct active low clear (CLR) input. Information at the data (D) inputs meeting the setup time requirements is transferred to the Q outputs on the positive-going edge of the clock (CLK) pulse.
