Part Number: SN74HCS4075-Q1 Tool/software: Hello I need the Pspice models of all the ones in the circled portion (3 input OR gates) Apparently the codes are given for 2 input only for majority of the cirled components
Part Number: SN74HCS4075 Hi TI,
Is there any open collector OR gate chip ? I need to specify the output high logic between 20 to 24V and I wanna avoid extra circuit at the output for this purpose.
Thanks
Part Number: SN74HCS4075 Hi,
The output of the OR gate,SN74HCS4075PWR, on pin 9 is supposed to be high, 3.3V when one of 2A, 2B, 2C is high, 3.3V. However when I measured it, it is only 2.36V. Then I disconnect it with the m ultivibrator , SN74LV123ADR,…
The rising edges indeed are much too slow. (See [FAQ] How does a slow or floating input affect a CMOS device? )
You need to use gates with Schmitt-trigger inputs, e.g., SN74HCS11/SN74HCS4075.
There is no such automotive-qualified device. You have to combine multiple OR gates; 3× 3 inputs (SN74HCS4075-Q1), or 4× 2 inputs (SN74LVC32A-Q1, SN74HCS32-Q1, SN74AHC32Q-Q1, SN74LV32A-Q1).

This question comes up fairly often because the HCS logic family is specified only at 2V, 4.5V, and 6V.
The following min / max values are interpolated from the datasheet tables…
