I have several of these, not sure where & when I got them. I have a hunch they're delay lines. I want to find a datasheet for them.
I've searched everywhere for the strings of letters / numbers without luck. They're 14 pin devices ... a bit thicker then typical ICs.
Karl, honest, I've...
Klaus, CALM DOWN. Relax.
Don't be so angry all the time. I've seen you repeatedly criticize people online here. When I post, I know you will respond negatively.
For gods sake, go outside and make a friend.
I've heard people say they will not post on this board because your such a ******...
I have a TL866II+ and some Lattice PALCE22V10H chips. I See that the IC select menu has GAL22V10's B, C, D. Which one is most compatible ? Should I use the lowest possible programming voltage selection ?
Thank you
Thank you very much Brad. I found a site called bitsavers.org. They don't have many individual 74xx data sheets, but they have hundred of full data books in PDF format.
I'm looking to build up a library of 74xx & 4xxx series datasheets. I know TI first developed the 74xx series of TTL chips - but I AM NOT interested in TI datasheets. I do not like the format.
I'd be very grateful if anyone could point me towards any online sources for datasheets. Yes, I have...
Am I looking at this circuit right ? For RS485 communication with this circuit, wouldn't the use of R5/C2 imply that there is a minimum bit rate that can be supported ? After the LOW start bit, if the next bit is a 1, and the bit rate is not fast enough, C2 charges up to the point where is...
Actually I'm just writing code I'll reuse a few times in various i2c periperals such as a keypad decoder and an IR remote tranciever. The keypad decoder would be fixed length, but the IR tranciever might be 4 to 10 bytes at a time, so I'll implement the two step process. First read the byte...
My question concerns the i2c protocol. I am using two microcontrollers, one is always the master, one always the slave. There is no i2c peripheral involved, just my two microcontrollers. I am familiar with the master/slave concept and the use of the read/write bit, etc. So, my description below...
Does anyone know of a source for reasonably priced SOP16 / SOCI6 to DIP adapters that are LESS THAN 0.5 inch across ?
All I've found on Ebay/elsewhere are adapters that are 0.8 x 0.6 inches. To fit my application I need about 0.8 x 0.4 inches.
I've been playing around with various means of controlling fan speed. The fan is a 'typical' 20 inch window fan with 3 speeds.
I have a variac and like the ability of that to control the fan speed.
I've tried a fan speed controller that I'm pretty sure uses a triac. That causes the fan to...
I am an interested in learning Java by developing dirt simple programs for my smart phone (Samsung S4 running some version of Android) - or PC (Windows 10 OS). Eventually I’d like to communicate via Bluetooth to my microcontroller projects.
For now I’d like to ask for advice on tutorials that...
