Part Number: SN74LVC1G139 Other Parts Discussed in Thread: SN74LVC1G29
Hello,
I need to use a fast decoder to be used in conjunction with an SRAM memory. As times are extremely critical, I looked for a decoder that was as fast as possible and also powered…
Part Number: SN74LVC1G139 Other Parts Discussed in Thread: CD74HC238 need the reverse polarity of SN74LVC1G139DCUR (meaning "1" in the relevant selected pin)
What is the right p/n?
Part Number: SN74LVC1G139 Other Parts Discussed in Thread: SN74LVC139A-Q1 , SN74AHC139 Dear expert,
I'm looking for 2 line to 4 line decoder, and found SN74LVC1G139, it's package size and performance could meet my requirement, but it's operating temperature…
Part Number: SN74LVC1G139 Other Parts Discussed in Thread: SN74HC04 Dear expert,
As title, I would like to double check with you.
Below is function table for 1G139, but I am looking for "when A,B are both high, Y0 Y1 Y2 Y3 are L L L H".
Did…
Other Parts Discussed in Thread: SN74LVC1G139 Hello,
I’m looking at using the SN74LVC1G139 to drive some LEDs directly, but I’m not confident on what the MAX output voltage would be for VOL (Max voltage at the pin when output is driven low).…
A cautionary note when using this chip for demultiplexing certain chips using the SN74LVC1G139DCU.
I am running the SN74LVC1G139DCU as a 2-to-4 multiplexer for four SPI chip select lines. I have one chip on output 3 that is sensitive to short transitions…
Hi,
want to drive LEDs, 5mA, from a xx139. But I need inverted function. If I connect the LED and resistor between Yx and ground it should work? Drive capabillity is +-24mA, so no problem ahead?
I end up with one of four LEDs is dark (one of the Y is lo…
Hi everyone,
I would like to use the 2-to-4 Line Decoder to select one out of 4 ICs for comunication via SPI (use as Chip select Distributor).
My imput signal Level is 5 Volts, but at the Output I Need only 3.3 Volts. Can I Archive this but Setting Vcc…
Part Number: SN74CBT3125C Other Parts Discussed in Thread: SN74LVC1G139 , TS12A44514 , TS12A44515 , TS12A44513 Hi All,
I have a question about SN74CBT3125C.
Is 1B output when VCC and 1A are shorted? When a voltage of VCC-0.8V or more is input to 1A, is the…
