SN74HC273N

The SN74HC273N from Texas Instruments is an octal D-type flip-flop featuring a direct active-low clear input. Information at the data inputs is transferred to the Q outputs on the positive-going edge of the clock pulse. This device offers a wide operating voltage range from 2 V to 6 V and a typical propagation delay of 12 ns, with a maximum of 27 ns at 6V and 50pF. It consumes low power, with a maximum ICC of 80 µA, and its outputs can drive up to 10 LSTTL loads, providing ±4 mA output drive at 5 V.

Designed for applications such as buffer or storage registers, shift registers, and pattern generators, the SN74HC273N contains eight flip-flops with single-rail outputs and individual data inputs. The device operates within a temperature range of -40°C to 85°C (TA). It is packaged in a 20-PDIP through-hole configuration, with a body size of 24.33 mm x 6.35 mm.

Key electrical characteristics include a clock frequency of 60 MHz and an input capacitance of 3 pF. The low input current of 1 µA maximum makes it suitable for various digital logic applications. The device is RoHS3 compliant and has an MSL of 1.
