1. Functional Description  
Dual Monostable Multivibrator  
2. General  
The 74HC123D is a high speed CMOS MONOSTABLE MULTIVIBRATOR fabricated with silicon gate C2MOS  
technology.  
It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power  
dissipation.  
There are two trigger inputs, A input (negative edge), and B input (positive edge). These inputs are valid for a  
slow rise/fall time signal (tr = tf = 1 s) as they are schmitt trigger inputs. This device may also be triggered by  
using CLR input (positive edge).  
After triggering, the output stays in a MONOSTABLE state for a time period determined by the external resistor  
and capacitor (RX, CX). A low level at the CLR input breaks this state. In the MONOSTABLE state, if a new  
trigger is applied, it extends the MONOSTABLE period (retrigger mode).  
Limits for CX and RX are:  
External capacitor, CX: No limit  
External resistor, RX: VCC = 2.0 V more than 5 k  
VCC 3.0 V more than 1 kΩ  
All inputs are equipped with protection circuits against static discharge or transient excess voltage.  
3. Features (Note)  
(1) Wide operating temperature range: Topr = -40 to 125 (Note 1)  
(2) High speed: tpd = 25 ns (typ.) at VCC = 5 V  
(3) Low power dissipation:  
Standby state: ICC = 4.0 µA (max) at Ta = 25 �  
Active state: ICC = 1000 µA (max) at Ta = 25 �  
(4) Balanced propagation delays: tPLH tPHL  
(5) Wide operating voltage range: VCC(opr) = 2.0 to 6.0 V  
Note: In the case of using only one circuit, CLR should be tied to GND, RX/CXCXQQ should be tied to OPEN,  
the other inputs should be tied to VCC or GND.  
Note 1: Operating Range spec of Topr = -40 to 125 is applicable only for the products which manufactured after  
July 2020.
