6116 SRAM PDF

The IDTSA/LA is a 16,bit high-speed static RAM organized The IDTSA/LA is packaged in pin mil plastic DIP, pin. The 5V CMOS SRAM is organized as 2K x 8. The offers a reduced power standby low-power (LA) version also offers a battery backup data. The IDTSA/LA is a 16,bit high-speed static RAM organized as 2K x 8. It is fabricated using IDT’s high-perfor- mance, high-reliability CMOS technology.

So I believe what is happening here 6116 the IDT part is sourcing much more current and burning up much more power. An LED’s IV curve is exponential, so if you give it a little more voltage, you get a lot more current.

So typically the output voltage of the IDT could be higher. I can view each byte of junk data the SRAM has been initialized with.

I have observed this behavior with all 3 IDT chips I ordered. Eli Lorden 12 2. Sign up using Email and Password. Sign up using Facebook. What value is the LED current-limiting resistor?

The SRAM chip does not appear to be damaged by this, as when power is cycled off and back on again it returns to working normally. At first everything works as expected. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

And be sure to use a separate resistor for each LED. After a while in this state the chip will begin to heat up and then all of the outputs switch to low, regardless of their previous state and without any intervention on my part.

What speed grade are your RAM chips, and where did you get them? Following this schematic, but using an IDT instead of the AS6C shown The chip is receiving 5V, which is within sfam tolerances listed on the datasheet. The chip is receiving 5V, which is within the tolerances listed on the datasheet.
