Rochester Electronics Logic - Flip Flops MC74HC273AF

The MC74HC273AF is an octal D flip-flop with common clock and reset inputs, designed for high-performance applications. It features eight D flip-flops that are loaded on the low-to-high transition of the clock input, with an asynchronous active-low reset. The device is compatible with standard CMOS outputs and can interface with TTL or NMOS outputs when used with pull-up resistors. This flip-flop operates within a voltage range of 2.0 to 6.0 V for HC versions and 4.5 to 5.5 V for HCT versions, making it suitable for various power supply configurations. It has a low input current of 1.0 µA and provides high noise immunity typical of CMOS devices. The MC74HC273AF can drive up to 10 LSTTL loads and is compliant with JEDEC standard No. 7A. The device is available in both SOIC-20 and TSSOP-20 packages, and it is Pb-free, halogen-free, and RoHS compliant. It is also AEC-Q100 qualified, making it suitable for automotive applications. The maximum clock frequency is 35 MHz, with propagation delays of 25 ns at 6.0 V. This product is ideal for engineers looking for reliable and efficient flip-flop solutions in digital circuits.
