Part Number: SN74HCS00-Q1 Hello Logic team,
What exactly is the difference between two Logic Families SN74HC S00 & SN74HC 132 ?
From datasheets, both parts look similar except minor differences in electrical parameters (like Supply current, ESD…
Part Number: SN74HCS00-Q1 Hello Team, following question from customer:
- Ínput switching thresholds:
Vcc = 2.5V but our datasheet only shows data for 2V, 4.5V and 6V.
Spec for 2V is VT+min 0.7V (means 35%VCC) and VT+max 1.5V (means 75%VCC)
…

Dear Texas Instruments Support Team,
We are experiencing inconsistencies in signal stretching behavior between different batches of the SN74HC00D NAND gate in our product…
Part Number: SN74LVC1G00 Other Parts Discussed in Thread: LM339 , SN74LVC00A , SN74HCS00 , SN74LVC1G10 Hello,
hoping to get some input on my design,
I want to latch some LM339 comparator output (active low) for overcurrent and ground fault, and i…
Hi Kaikai,
Clemens is correct there is no information for this marking. It may be very old, or a custom part for a customer.
We do not have any newer bipolar devices,
For TTL compatible, this device should be a good replacement: https://www.ti.com…
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…
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…
Hi,
There will be no difference between SN74HC138 and SN74HCS138 in terms of specs. The HCS family is going to be p2p with the HC family. The HCS family however includes some features such as schmitt-trigger inputs which greatly improves signal integrity…
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…
Hi Hans,
This device has a recommended supply voltage of up to 3.6V. Operating at a higher voltage is possible but will reduce reliability as all the datasheet specs are tested with a voltage supply up to 3.6V. I would recommend using the SN74HCS00…
