Frequently Asked Questions
What is the maximum operating frequency of CD74HC73M and what load capacitance is rated?
CD74HC73M operates at a maximum frequency of 20 MHz with a rated load capacitance of 50 pF, making it suitable for medium-speed synchronous counter, divider, and state machine designs in digital logic systems.
How does the master-slave operation in CD74HC73M benefit edge-triggered flip-flop designs?
Master-slave operation in CD74HC73M ensures that the output changes only on the falling clock edge, preventing race conditions and glitches in sequential logic. With 6 mA output sink current, it reliably drives capacitive loads in bus-connected digital systems.
Which package does CD74HC73M come in and how many flip-flop channels does it provide?
CD74HC73M comes in a 14-pin SOIC small outline package and provides 2 independent J-K flip-flop channels, each with its own clock, J, K, and active-low reset inputs for flexible sequential logic configurations.
When would CD74HC73M be chosen over a D-type flip-flop for a frequency divider design?
CD74HC73M's J-K topology allows direct toggle-mode division without external feedback by tying J and K high, whereas a D-type flip-flop requires Q-to-D feedback wiring. At 20 MHz max frequency and 50 pF load, it is well-suited for divide-by-2 counter stages in crystal oscillator circuits.
