  • SN7404: The signal voltage level conversion IC recommendation

    TI Thinks Resolved
    Part Number: SN7404 Other Parts Discussed in Thread: UCC27517 , TXH0137D , CD40109B , TXH0137D-Q1 , UCC27424 Hi， I am looking for a voltage level conversion chip or buffer. I need to convert my signal voltage from 3.3V to 15V. SN7404D seems not to be the right…

  • SN7404: Radiation-hardened /space qualified components vs components with space heritage

    Answer Suggested
    Part Number: SN7404 Hello, Often you will find the same component in both categories, but what about “normal” components with space heritage? I am thinking about plastic packages with more than one BJT transistor (for instance opams and logic…

  • RE: SN74AVC4T245: Improve reliability by add resistance on control pin

    Resolved
    That sentence talks about old, bipolar devices with multi-emitter inputs (e.g., SN7404, SN74S04). For all other devices, see the previous paragraph: If a low level is required, the input should be directly connected to GND; if a high level is required…

  • RE: SN74LVC2G04: Inverter that supports level conversion with VCC=5V, Vin=3.3V, Vout=5V output

    It seems possible with the TTL SN7404, but it's a legacy product and only has 6 channels. I'd prefer a 2-channel product that's as new as possible.

  • SN7404: SN7404N: ESD information

    TI Thinks Resolved
    Part Number: SN7404 Hi E2E, Good day! Checking on the Qualification Summary of SN7404N, it states to the datasheet for the ESD information. However, no ESD information is included on the datasheet. Can you please provide. Thank you in advance. Best…

  • SN7404: Schematic has unrecognised symbols

    TI Thinks Resolved
    Part Number: SN7404 On page 4 of the data sheet there are schematics for each gate in the chip. The LS04 and S04 schematics include a symbol that looks like a BJT transistor, but the "base" component has what looks like Zenner symbol attached…

  • grounding the SN7404

    Other Parts Discussed in Thread: SN7404 I'm assembling the SN7404 on a bread board. The instrument requires a supply voltage of 5 V and ground to operate. I have a 5 V dc power supply, therefore would i connect the negative from the power supply to the…

  • SN7407: Input voltage even with pulldown?

    Resolved
    Part Number: SN7407 Other Parts Discussed in Thread: SN7404 , SN74LS07 , SN74LVC07A , Hello, Im having an issue with the SN7404 IC. The image bellow shows how it is designed. The R7 Resistor Array is used to pull down the 7407 input, so when the CN7 connector…

  • RE: SN74HC14: want to TTL craft product instead of CMOS Craft product

    Why? If you need to handle TTL signals, you can use CMOS devices with TTL-compatible inputs. TTL: SN74LS14, SN7414 SN74ALS04B, SN74LS04, SN7404 SN74ALS32, SN74LS32, SN7432 SN74ALS08, SN74LS08 SN74ALS165, SN74LS165A TTL compatible: SN74AHCT14, SN74HCT14 SN74AHCT04…

  • RE: SN74HCS244-Q1: "Convert" digital 3.3V to 5V

    Resolved
    This board will be in a ~60°C environment, so I think there is no need to be an automotive part. I will need 7 channels, I was planning to use 2 SN7404 on my board. I didnt look at voltage translators, thank you, will give it a look. Is there any advantage…
