It comes in a 20-pin DIP package (0.300\" body) for through-hole mounting — the kind you can socket and swap on site without a hot-air station. Clock frequency hits 60 MHz, supply range is 2V to 6V, and the operating temperature spans -55°C to 125°C, so it is rated for avionics, downhole, or satellite environments, not just a benchtop. Quiescent current sits at 8 µA, output drive is 5.2 mA per pin both high and low. This is a standard building block for register, latch, and buffer applications where you need eight bits of edge-triggered storage with a clean asynchronous reset. ## 60 MHz clock and propagation delay — what they mean for your bus Max propagation delay is 26 ns at 6V with a 50 pF load. The 60 MHz clock is the input toggle rate, not the system bus speed. ## Field-swappable — socketed DIP, no bench required 20-pin DIP with 0.300\" row spacing. Through-hole mounting means you can socket it — swap it on site with a chip puller and a fresh part, no reflow, no hot air. Pin 1 orientation is marked by a notch on the package end. Input capacitance is 10 pF per pin, so the clock line sees a light load. The master reset is active-low; leave it high for normal operation. Output drive is 5.2 mA — enough to light a standard LED or drive a CMOS input, but not a relay coil. If you need more current, buffer the outputs.","metaTitle":"CD74HC273E D-Type Flip-Flop, 60 MHz, 20-DIP, Active","metaDescription":"CD74HC273E 8-bit D-type flip-flop with master reset, 60 MHz clock, 2V–6V supply, -55°C to 125°C.
