Frequently Asked Questions
What is the maximum operating frequency of CD74HC74ME4 and what load capacitance does that apply to?
CD74HC74ME4 supports a maximum clock frequency of 20 MHz when driving a 50 pF load capacitance. At lower supply voltages or higher load capacitances, the achievable toggle rate decreases, so designers should derate the frequency accordingly when using long PCB traces or bus capacitance above 50 pF.
How can CD74HC74ME4 be configured as a divide-by-2 frequency divider?
Connect the /Q output back to the D input of one flip-flop element in CD74HC74ME4. Each rising edge on the clock input then toggles the Q output, producing a 50% duty-cycle output at exactly half the input clock frequency, up to 20 MHz with a 50 pF load, useful for clock-tree management and baud-rate generation.
Which package does CD74HC74ME4 use, and how does it affect PCB space compared to a DIP alternative?
CD74HC74ME4 comes in a 14-pin SOIC package with 1.27 mm lead pitch and a body width of 3.9 mm, occupying roughly 60% less PCB area than an equivalent 14-pin DIP. The surface-mount format enables tighter board layouts in space-constrained consumer and industrial designs.
Is CD74HC74ME4 compatible with 3.3 V logic systems alongside 5 V HC-family devices?
CD74HC74ME4 is part of the HC family, which operates across a supply range that includes 3.3 V and 5 V. At 3.3 V supply, the output sink current is 4 mA and the maximum operating frequency is lower than at 5 V, so compatibility with 5 V downstream devices should be verified against the VIH thresholds of those devices before connecting directly.
