SN74HC273DWR

The SN74HC273DWR is an octal D-type flip-flop with a direct active-low clear input, manufactured by Texas Instruments. It is designed for applications such as buffer or storage registers, shift registers, and pattern generators.

This device features a wide operating voltage range from 2V to 6V and a maximum clock frequency of 60 MHz. The typical propagation delay is 12 ns, with a maximum of 13ns at 6V and 50pF. It consumes low power, with a maximum ICC of 80 µA and a low input current of 1 µA maximum. The outputs can drive up to 10 LSTTL loads and provide ±4-mA output drive at 5V.

The SN74HC273DWR is available in a 20-SOIC package with surface mount mounting type. It operates within an ambient temperature range of -40°C to 85°C. The flip-flop contains eight individual flip-flops with single-rail outputs and a direct clear 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. Clock triggering occurs at a particular voltage level and is not related directly to the transition time of the positive-going pulse. When CLK is at either the high or low level, the D input has no effect at the output.
