The MC14490DWG is a hex contact bounce eliminator constructed with complementary MOS enhancement mode device and is used for the elimination of extraneous level changes that result when interfacing with mechanical contacts. The digital contact bounce eliminator circuit takes an input signal from a bouncing contact and generates a clean digital signal four clock periods after the input has stabilized. The bounce eliminator circuit will remove bounce on both the make and the break of a contact closure. The clock for operation of the eliminator is derived from an internal R-C oscillator which requires only an external capacitor to adjust for the desired operating frequency.
- Diode protection on all inputs
- Internal pull-ups on all data inputs
- Can be used as a digital integrator, system synchronizer or delay line
- TTL compatible data inputs/outputs
- Cascadable for longer time delays
- Chip complexity - 546 FETs or 136.5 equivalent gates

Sturdy case large enough for most keyboards, with space for a mouse.
This is a great case that will protect most keyboards very well. My keyboard and mouse set is from Jelly Comb, and they fit well. It’s very spacious inside. In fact, my keyboard is thinner than what this case is designed for, so I had to pad the keyboard so it won’t move around too much, but I don’t consider this a bad thing. Now I know that if I get a larger keyboard, I can still use the same case. I also like the way it’s designed for a mouse. There are two pouches on top that indent into the case, so you can easily fit a mouse or cables in there and they won’t protrude too much. This case is perfect, and I can’t recommend it enough.

Nice case for carrying keyboards
The case is perfect for carrying keyboards or other items. I am using it for an apple keyboard and trackpad.

Excellent Quality and Worth Every Penny!
Size: 11.25“, Color: black-6 pack
I recently purchased the LEOPO 12-inch Shelf Brackets, Thick Heavy Duty Industrial Brackets, and I couldn’t be more impressed. The craftsmanship is exceptional—solid, well-constructed, and clearly designed with attention to detail. Installation was quick and effortless, and the brackets held perfectly level and secure right from the start.
They feel incredibly sturdy once mounted, providing reliable support and excellent stability for heavier shelving loads. The overall durability and performance exceeded my expectations, especially for the price.
I’d highly recommend these shelf brackets to anyone looking for strong, stylish, and dependable hardware to upgrade their storage or décor setup.

very nice brackets..very sturdy. Fits a 1x10 board perfect. Comes with everything you need and a.cool little level also. I loved them.so much I bought another pack and decided to add more shelves for my plants. It was easier to mount the shelf to the bracket then mount the whole shelf. Holds almost all my plants some are pretty heavy.
