Part Number: SN74HC132 Other Parts Discussed in Thread: SN74HCS00 Hello Guys,
Good day.
Our customer is using the SN74HC123 in the fan tach monitoring application. His fan tach is using 12V and the SN74HC123 is a 5V device. Is the input clamped to Vcc…
Hi Tarrin,
You are correct. The SN74HC03 has an input and output protection circuit similar to that shown in figure 8 of the SN74HCS00 datasheet. If you're looking for a gate without this protection circuitry, you might try the SN74LVC2G38.
Thanks…
Part Number: SN74HC138 Other Parts Discussed in Thread: SN74HCS138 , , SN74HC00 , SN74HCS00 , SN74HCS139 Hello
do we have IBIS model for the SN74HC138NS, SN74HC139NS?
best regards,

Part Number: CD4093B Other Parts Discussed in Thread: SN74HCS00 Hi team，
My customer needs to know the electrostatic parameter when using CD4093BM, which is not given in the datasheet. Could you help to provide the parameter value. Thank you.
Best Regards…
Whatever happens on CLK does not matter for initialization, because the initial state is unknown to begin with . You always need a low pulse on PRE .
During power up, there is no initialization time; after the supply has reached the minimum allowed voltage…

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…
