Part Number: SN74HC139 Hi,
We are using SN74HC138PWR and SN74HC139PWR decoders in our circuit supplied by VCC=3.3V. In the datasheet, I am not able to find the IO Level for VCC=3.3V.
Can you please let us know the High and Low IO Level for VCC 3…
Part Number: SN74HC139 Hello guys,
One of my customers has the following questions about SN74HC139NSR and other logic ICs. Could you please give me your reply?
Q1. How much is SN74HC139NSR ESD (MM, HBM, CDM) performance? Q2. When I want to check ESD…

Hi, This data sheet does not list the absolute maximum ratings of the input and output pins. Could you tell me the absolute maximum voltage ratings of the input and output pins? Customer needs this information for device review…
Part Number: SN74HC139 Other Parts Discussed in Thread: TINA-TI Hi all Would you mind if we ask SN74HC139? Do you have SN74HC139NSR's IBIS model? If you have it, could you give us? Kind regards, Hirotaka Matsumoto
Part Number: SN74HC139-Q1 Hi Team, My customer's application is Vcc=3.3V. I would like to ask about the following. 1) Is there VIH_min and VIL_max value under Vcc=3.3V? 2) Is there tpd_max (A or B to Y, notG to Y) value under Vcc=3.3V? Best Regards, Yaita…
Hi Bill,
For a lot of older parts that haven't gotten datasheet updates yet, the best place to ask is here.
The SN74HC139 passed up to 3kV for HBM, and 200V for MM. I don't see a record of a CDM test.
I know that datasheet is on your list as one…
There is no P2P device.
A digital demultiplexer like the SN74HC139 drives the selected output low and the other three outputs high.
If the unselected outputs must be Hi-Z, then you could use a three-state buffer like the SN74AHC125.
