Other Parts Discussed in Thread: ULN2003V12 , CD74HCT4067 , DRV8860 , TIDA-00117 Hi,
I need to drive a relay coil rated 12V DC coil voltage, 720 ohm coil resistance and 200mW switching power. Instead of using a driver for each and every relay, I want to…
Other Parts Discussed in Thread: CD74HCT4067-Q1 Hi All,
Since CD74HCT4067-Q1 is bidirectional, can it accept negative input voltages also? If not, is there any analog mux that accepts negative input voltages?
Thanks
The input voltage must be above V IH . In practice, the signal level should be identical with V CC .
Input voltages between V IL and V IH indeed cause increased power consumption and potential damage; see [FAQ] How does a slow or floating input affect a CMOS…
Part Number: TMUX1308 Other Parts Discussed in Thread: CD74HCT4067 , TMUX1237 , TMUX1247 I plan to use one 3.3V UART of the MCU to connect with 8-set or 16 -set MCU (different MCU) with only one connection is active. Can you recomment the proper MUX ? Thanks…
Part Number: CD74HC4067 Other Parts Discussed in Thread: CD74HCT4067 Hi
I am using CD74HC4067 mux and I have some unused input pins. Is it OK to keep these unused input pins floating or should I need to pull these pins either to VCC or GND
Hi Kurumi,
I have some concerns with this application - please see below for the concerns as well as a potential work around.
1. you don't need a 12 channel mux - you need a 2 channel 12:1 multiplexer (12 inputs to 1 output and vice versa). We don't have…

They use a lot of MUXes in front…
Part Number: CD74HC4067 If i select an Output which is off, what state does it have? Is it grounded or in Tri-state? Or floating off?
Tank you for your help.
Almerindo,
Unfortunately I know very little about the part except for what is in the datasheet. You might try posting your question in the Logic forum. I would assume that the ESD protection would conduct current and could potentially damage the device…
