Frequently Asked Questions
What supply voltage range does the CD74HC123M96 support, and how does it affect output drive strength?
The CD74HC123M96 operates over a 2 V to 6 V supply range. At 4.5 V, it can source and sink 4 mA of output current, making it compatible with standard 3.3 V and 5 V digital logic systems without level-shifting components.
How can CD74HC123M96 be configured to generate a 1 µs one-shot pulse in a digital timing circuit?
Select an external resistor of about 10 kΩ and capacitor of 100 pF connected to the Rext/Cext pins. This RC combination sets the output pulse width to approximately 0.7 × R × C = 0.7 µs to 1 µs per channel, giving precise timing control for single-shot triggering events.
When should designers choose CD74HC123M96 over a microcontroller timer peripheral for pulse generation?
CD74HC123M96 is preferred when hardware-guaranteed retriggerable monostable behavior is needed without firmware overhead. It delivers deterministic 2 V to 6 V logic pulses with propagation delay under 20 ns at 4.5 V, saving 8 or more MCU clock cycles per event and freeing CPU resources for other tasks.
