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.

Post as a guest Name. 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 ssram part.
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.
And be sure to use a separate resistor for each LED. What speed grade are your RAM chips, and where did you get them? I am building a memory module for an 8-bit computer, and am running into an issue.

Following this schematic, but using an IDT instead of the AS6C shown The chip is receiving 5V, which is within the tolerances listed on the datasheet. I can view each sarm of junk data the SRAM has been initialized with. The chip is receiving 5V, which is within the tolerances listed on the datasheet. An LED’s IV curve is exponential, so if you give it a little more voltage, you get a lot more current.

So I believe what is happening here is the IDT part is sourcing much more current and burning up much more power. I have 61116 the outputs to 8 LEDs and tied all address inputs low.
At first everything works as expected. So typically the output voltage of the IDT could be higher. Sign up or log in Sign up using Google. I have observed this behavior with all 3 IDT chips I ordered. What value 6116 the LED current-limiting resistor?
