Product Summary
The 74LV123DB is a Dual retriggerable monostable multivibrator with reset. It is a low-voltage Si-gate CMOS device and is pin and function compatible. The 74LV123DB uses three methods to control the output pulse width.
Parametrics
74LV123DB absolute maximum ratings: (1)DC supply voltage: –0.5 to +7.0 V; (2)DC input diode current(VI < –0.5 or VI > VCC + 0.5V) : 20 mA; (3)DC output diode current(VO < –0.5 or VO > VCC + 0.5V) : 50 mA; (4)DC output source or sink current standard outputs(–0.5V < VO < VCC + 0.5V) : 25 mA; (5)DC VCC or GND current for types with standard outputs: 50 mA; (6)Storage temperature range: –65℃ to +150℃.
Features
74LV123DB feature: (1)DC triggered from active HIGH or active LOW inputs; (2)Retriggerable for very long pulses up to 100% duty factor; (3)Direct reset terminates output pulses; (4)Schmitt-trigger action on all inputs except for the reset input; (5)Output capability: standard (except for nREXT/CEXT); (6)ICC category: MSI.
