  • Forum Post: SN74ALVC244 drive capacitance

    Paul Peterson52746
    I am looking at obtaining this part http://focus.ti.com/docs/prod/folders/print/sn74alvc244.html . However I can not find on the datasheet or on the web how much capacitance the buffer can drive. The current setup can drive approx 70 pF but when you add up the capacitance of the card and the coax we...

  • Forum Post: input transition rate SN74AUP3G17 vs. SN74AUP1G17

    Matthias Geipel
    Hello, according to the datasheets of the SN74AUP3G17 (triple buffer) and SN74AUP3G14 (triple inverter) a max. input transition rise/fall rate of 200ns/V is recommended, although these devices feature Schmitt trigger inputs . For the single gate (SN74AUP1G17 / SN74AUP1G14) and dual gate versions ...

  • Forum Post: ADC Data buffer needed for customer

    Sarah Pardee
    Here’s list of requirements for an ADC data buffer that my customer needs: 1.) Can either be one 32bit buffer IC, or two 16bit buffer IC’s (Note: Two 16bit buffers are somewhat preferred). 2.) In/Out frequency is 96MHz. 3.) In/Out Signal Type is CMOS @ 1.8V, and is unidirectional...

  • Forum Post: SN74LV8151 Input Voltage Tolerance

    Robert DeMott
    Could someone confirm whether the SN74LV8151 inputs are 5V tolerant when operating from a 3.3V supply? The recommended operating conditions section of the datasheet seems to imply that they are (max input voltage of 5.5V), but this isn't explicitly stated in the part description. Thanks.

  • Forum Post: partial power down Ioff

    Dan-o
    I am a little confused on partial power down Ioff. Is that the current which the part will use when there is no VCC (i.e. it will pull this small amount of current from the input/output pin when there is no VCC)? Or is that the maximum amount of current you can have at one of the pins when the is no...

    Massimo Ferracini
    Hello, I have just tested a new DLP board featuring some SN74AUP3G17 parts. We selected the RSE fooprint, and following component datasheet we designed the net connections: Unfortunatelly, after board testing, I've found that input/output pins are inverted: e.g., channel 1 input is at pin...

    Hello, Can PCA9306YZTR be used for level shifting and also i2c buffer? Also is there any problem to use ESD protection for I2c lines? will it interfere with I2c operation? thanks

  • Forum Post: SN74LVC2244A Supply voltage

    Sakthi Kumar
    Does TI plan to support 1.5V supply voltage for SN74LVC2244A? As of now it is rated from 1.65V.

  • Forum Post: Bus width resizing 16Bit to 8Bit

    Sebastian Kruber
    Dear TI-Team, for our application we need to connect a 16Bit wide camera port (YCbCr) to a 8Bit wide interface (OMAP). What logic can you recommend to serialize the 16Bit data to 2x8Bit data? Regards, Sebastian

  • Forum Post: 5V Tolerant Input 3.3V Buffer, with shared footprint between Mil temp and Commercial Temp

    AndrewKMak
    Hi, I am wondering if Ti have a (Single, Quad, Octal, etc) buffer that supports: 1) 5V Tolerant Input 3.3V output 2) Common footprint between Mil temp and Commercial Temp Or two parts that share the same footprint, so there is an upgrade path from commercial to military temp. Thank you! ...

  • Forum Post: SN74LVC244A Question about "Continuous output current"?

    Jean Decuigniere
    Hi all, I would like to use the buffer SN74LVC244A and I see in the datasheet that the Continous output current is (+/- 50 mA). But I don't know if it's +/- 50 mA per pin or +/- 50 mA for the 8 pins total? Best regards, Jean Decuigniere.

  • Forum Post: SN74LVC1G17 logic buffer: can it drive a long PCB track with 75Ohm impedance parallel terminated by 75Ohm resistor at the end?

    Liang Zhou1
    Hi: I need to select a buffer for a 3.3V logic sigal from CPLD. The signal is a few MHz can have to travel 3 feet long of PCB track. If the pcb track impedance is 75Ohm, and I use 75Ohm parallel termination. Then the current consumption is 3.3V/75Ohm=44mA. But the SN74LVC1G17 output is 24mA. I...

  • Forum Post: SN74AVC16374ZQL Pinout

    Andy Goulbourne
    Hi, just a quick one Is the ZQL pinout for the 74AVC374 the same as the GQL pinout? The datasheet lists the pinout for the GQL (page 2), but only the ZQL is available for purchase. Thanks in advance
