Marketing proposal for customer feedback. V DD and ground, pins 14 and 7, are the power pins. This is image of IC this is the pictures of catasheet Ic Please login or register. CMOS devices can be damaged by static electricity simply by touching them out of circuit with your bare hands, and it gets worse from there.
Product is under characterization. I have a problem with my Midifly series. They are not as rugged as something like catasheet opamp. This means that either side of the switch can be used as the input. As long as it is a CD, it should work. Product is in volume production only to support customers ongoing production. A bilateral switch acts as a single pole, single throw switch. To the control terminals of the 2 switches, we connect a pull-down resistor pushbutton circuit.
Product is in design stage Target: First, to power thewe connect 5V of power to V DDpin 14, and we connect the ground pin, pin 7, to ground. In theory, it should be working fine.
In this circuit, we will show the basic functionality of the chip by passing analog signals through 2 of the switches by hcf control. Media Subscription Media Contacts.
I think they are actually pretty rugged these days, but it seems like the process that they are using for ICs like this are getting more intolerant of signal quality on the control pins. Not Recommended for New Design. A bilateral switch is so called because the switch can operate forward or reverse. I would either have third party look at it to determine if the repair work is at fault or not, or see if you can get a new circuitboard.
The really functions as an analog switch. So current can flow in one direction and the other direction, depending on which side is the input. Communications Equipment, Computers and Peripherals. May 28, Selectors Simulators and Models. Support Center Complete list and gateway to support services and resource pools. Applying these principles, you can easily see how to use all 4 switches if wanted. As the quad term implies, the is composed up of 4 switches. Been there, done that.
IoT for Smart Things. If so, I wonder if that might be a factor. No availability reported, please contact our Sales office. HCF Datasheet PDF — STMicroelectronics So you will see that if you press down the pushbutton with an analog signal or digital signal at the adtasheet, that same signal will appear at hte output. Maybe a picture will help.
When unpressed, the pushbutton has the signal LOW by default. You can view the control terminal as the signal which closes the switch so that the input signal can cross over to the output. If the pushbuttons are not pressed down, then no signal will appear at the outputs. Each switch has an input, output, and control terminal. I wonder what might have happened right before this problem started — things like the wrong polarity on a battery can mess up a lot of things.
The pinout of the chip is shown below. Limited Engineering samples available Preview: Most Related.

All the products will packing in anti-staticbag. Ship with ESD antistatic protection. We will inspect all the goods before shipment,ensure all the products at good condition and ensure the parts are new originalmatch datasheet. After all the goods are ensure no problems afterpacking, we will packing safely and send by global express. It exhibitsexcellent puncture and tear resistance along with good seal integrity. Guarantees 1.
Salabar In this circuit, we will show how to connect a bilateral switch chip to inputs and outputs using the quad bilateral switch chip. Product is in volume production Evaluation: One place it can be obtained is at Taydaelectronics at the following link: CMOS devices are especially sensitive to static electricity. Same pinouts, same description of what it does, etc. It can be obtained cheaply at a number of online electronic retailers. My vote is for a bad solder joint, a solder bridge, or the PCB being damaged from the process of removing the old chip. Anyone, help me please, thanks That was not the case a decade ago, but they had other problems back then.
