The PCA9555 (or any other I/O expander) cannot generate timing patterns.
To generate a pulse, use a monostable multivibrator like the SN74LVC1G123 and an inverter. Alternatively, use an XNOR gate with Schmitt-trigger inputs (e.g., SN74LVC1G57) with an…
Part Number: SN74LVC1G07 Other Parts Discussed in Thread: SN74LVC1G32 , SN74LVC1G97 , SN74LVC1G57 Hi Sir,
May I know if we have buffer with enable pin control?
I need non-inverting, open drain output and one channel buffer.
Thank you.
Hello,
For the simplest / smallest solution, I would recommend using this circuit:
For the gate, you can use the SN74LVC1G57. It can be configured easily as a single inverted input NAND gate, has Schmitt-trigger inputs that are over-voltage tolerant to…
Hi Jim,
We have a few " configurable multi-function " logic gates. Such as the SN74LVC1G57 . However, they all have the same pin layout and will not be a P2P replacement as they need 3 inputs to have configurability (see below).
If you need to…
Hi Tim,
Some background: Almost all of PSpice models available on the web currently were automatically generated. So any that weren't will have to be manually created by me.
If you'd like, I can get started on creating the models for the SN74LVC1G57…
Part Number: SN74LVC1G98 Other Parts Discussed in Thread: SN74LVC1G57 Hi,
We are using SN74LVC1G98DRYR in our design. we need Juction-to-Ambient/case thermal impedence for "DRY" package. This is not given in the datasheet. can you please provide this information…
Part Number: SN74AHC1G04 Other Parts Discussed in Thread: SN74LVC1G57 , SN74LVC1G14 hi dear supporting team,
customer found PIN2 of SN74AHC1G04QDCKRQ1 has a short term -0.8V voltage, while in the d/s, it mentioned the min voltage is -0.5V, the waveform…
Part Number: SN74LVC1G08 Other Parts Discussed in Thread: SN74LVC1G57 Hi Sirs,
Sorry to bother you.
We will use TI SN74LVC1G08 to replace NXP 74LVC1G08GW
We think it's p2p.
Our end customer saw NXP datasheet have show "Schmitt trigger action at all…
