The CD74HC73M is a dual negative-edge-triggered J-K flip-flop with reset functionality, utilizing high-speed CMOS technology. It features hysteresis on clock inputs for improved noise immunity and faster input rise and fall times. The device supports asynchronous reset and provides complementary outputs with buffered inputs. It operates at a maximum frequency of 60 MHz at a supply voltage of 5 V and can drive up to 10 LSTTL loads on standard outputs and 15 LSTTL loads on bus driver outputs. The operating temperature range is wide, from -55¬8C to 125¬8C, making it suitable for various applications. The CD74HC73M is available in a 14-pin SOIC package, measuring 8.65 mm by 3.90 mm. This product offers significant power savings compared to LSTTL logic ICs, making it a viable option for engineers seeking efficient and reliable flip-flop solutions.
