Part Number: SN74AHC4066 Tool/software: Hi.
I have a question regarding the SN74AHC4066RGYR device in the VQFN package.
While the datasheet states that the exposed thermal pad must be soldered to the PCB for thermal and mechanical performance, it…
Part Number: SN74AHC4066 Other Parts Discussed in Thread: TMUX1511 We use SN74AHC4066 ( QFN − RGY) in our product to switch signals between camera and lens. Power supply from camera is 5V, signal levels are normally in 0 - 5V range.
The problem is that…
Koji,
You are correct we a -3V signal violates the recommend operating conditions stated in the datasheet 0V to Vcc. Placing -3V on the I/O path of the SN74AHC4066 also violates the absolute recommended operating condition and could cause permanent…
Rushi,
The package suffix D, DB, DGV, N, NS, OR PW are TI naming convention to differentiate a package type (PDIP,SOIC, QFN, etc), pin pitch, and package height.
You can search all of TI package drawings by common industry package terms like Plastic…
Part Number: SN74HC4066 Other Parts Discussed in Thread: SN74AHC4066 , Tool/software: Hello,
we got PCNs from different sources, that stated SN74HC4066PWR to be obsolete from June '24. As this part is marked as active on TI website ( https://www.ti…
In theory, pulling OE low should disable everything. Please show the schematic.
(And it still would be a better idea to use an analog switch like the SN74AHC4066.)
The TXS is a level shifter, and does not isolate anything (for low signals, there exists a direct connection through the chip).
The datasheet says:
To ensure the high-impedance state of the outputs during power up or power down, the OE input pin…
Part Number: TXS0108E Other Parts Discussed in Thread: SN74CB3Q3245 , SN74AHC4066 I'm using a TXS0108EPWR to buffer and translate some UARTs between a processor and an FTDI USB chip. The TX and RX pairs to the processor are all on the "A" side and the…
