You can view the control terminal as the signal which closes the switch so that the input signal can cross over to the output. It datasheet have been damaged by static electricity. This enables the signal at the input to go to the output.

Each switch also has a control or enable terminal. V DD and ground, pins 14 and 7, are the power pins. This establishes sufficient power to the chip.

No availability reported, please contact our Sales office. May 27, The switches are labeled from 1 to 4. I think the TI parts always worked, but that was after trying others that seemed to work OK in other circuits when I checked a few. The is a pin chip. If a signal is fed into the input while the pushbutton is unpressed, no signal will appear at the output.

It can be obtained cheaply at a number of online electronic retailers. Product is in volume production Evaluation: IoT for Smart Things.

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. Originally posted by corns cdbcm is the original of dimarzio,s pre amp for midyfly above and hcf Is the subtitute for cdbcm but “it doesnt work” is that matter?

For me it was only a pain in battery powered circuits since voltage varies a little and current is a concern – I had to put some actual thought into what I was doing. As the quad term implies, the is composed up of 4 switches. The quad bilateral switch chip is a chip that is made up of 4 switches. 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.

General terms and conditions.

HCF Datasheet, PDF – Alldatasheet

In this circuit, we will show the basic functionality of the chip by passing analog signals through 2 of the switches by digital control. And you can’t see if it has been damaged by static, either. When unpressed, the pushbutton has the signal LOW by default. Concrete by Design Personal. Distributor Name Region Stock Min.

My vote is for a bad solder joint, a solder bridge, or the PCB being damaged from the process of removing the old chip. Computers and Peripherals Data Center. The radiation hardness, single event latch-up SELsingle event upset SEU immunity, and the housing in hermetic packages of all types of both series make them usable in the most difficult environmental conditions.

In this circuit, we will show how to connect a bilateral switch chip to inputs and outputs using the quad bilateral switch chip. That’s not to say that the TI ICs will work here or that other issues might not exist, dafasheet if one brand if does not work and you have eliminated everything else – it’s not crazy to try another brand.

In theory, it should be working fine. Maybe a picture will help. One place it can be obtained is at Taydaelectronics datashdet the following link: ST Code of Conduct Blog. Communications Equipment, Computers and Peripherals. As long as it is a CD, it should work.

So current can flow in one direction and the other direction, depending on which side is the input. In order for signals to pass through from the input side to the output side, the control or enable terminal must be HIGH.

It’s very easy to damage some PCBs and I’ve had cold solder joints that look like they should be great.

If the switching signal is marginal, or not filtered well, then you can have problems with some manufacturer’s CD parts and some models of those parts in some cases. The pinout of the chip is shown below.
