Part Number: CD74HC123 Hi, We have recently purchased the below two parts from Arrow and find that some of the parts pin are Yellowish Colour.
MPN : CD74HC123E Date Code : 1814
MPN : CD4094BE Date Code : 1752
Please advise if this is ok to use or some problem…
Part Number: CD74HC123 Hi all Would you mind if we ask CD74HC123PW? How much is the max power dissipation? Tjmax(150C)=PD×108C/W+Ta(For example 45C) ->105/108=0.97W, is it correct? And then, is the formula of power dissipation as follows? PD=(Cpd + CX…

Hi all Would you mind if we ask CD74HC123? <Question1> There is the formula "tW = 0.45 Rx Cx in case of Vcc = 5.0V" on the datasheet. In case of Vcc=3.3V, is tW's caluculation a the same as tW = 0.45 Rx Cx? Compared…
Part Number: SN74LV123A Other Parts Discussed in Thread: CD74HC123 Hi Team,
can you confirm that SN74LV123A can be used as an alternative for 74HC123

Part Number: CD74HC123 Hello,
we used CD74HC123E as mono stable by using input pin 1( -1A) and Output Pin 13( 1Q). Input negative pulses will receive by motion sensor and output goes on for 21 seconds. So this solution is used in our street light product…
Other Parts Discussed in Thread: CD74HC123 Hi all; I have a couple of questions about this part. I hope someone can help.
1) Can the output pulse width be shorter (in time) than the input pulse used to trigger it? I want to use a 10 second pulse to trigger…
Part Number: SN74AHC123A Other Parts Discussed in Thread: CD74HCT123 , , CD74HC123 Hi, Teams,
Please help to double TI has the same as the 74HC123, and I have checked the TI family,
tw = K * RT * CT; need K=0.45 and tw<5ns.
CD74HCT123: K=0.45 but tw=17…
Hi Karan, thanks again for your reply. I am trying to create a nanosecond pulses generator that is able to create nanosecond pulses (50ns) for a variety of output voltages varying from 1~5V. I got the right timing resistor and capacitor combination working…
Other Parts Discussed in Thread: CD54HC123 , CD74HC123 The pulse widths produced using CD54HC123 (3.3V) are about 20% shorter than calculated.
The problem was originally noticed with 143K and 2.2uF. We performed several experiments including different…
Here is an appnote that may help. There will not be any harm or side affects at these longer pulse widths. There will be a point wher the resistor or capacitor will have no affect.
