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.

An LED’s IV curve is exponential, so if you give it a little more voltage, you get a lot more current. What value is the LED current-limiting resistor? Home Questions Tags Users Unanswered. So typically the output voltage of the IDT could be higher. Increase the 61116 limit the LED’s or remove them, yeah its cool to see the data go by but useless and the problem in all likelihood will go away.
Sign up using Facebook. The chip is receiving 5V, which is within the tolerances listed on the datasheet.
After a while in this state the chip will begin to heat up and then all of the outputs switch to low, regardless dram their previous state and without any intervention on my part. I can view each byte of junk data the SRAM has been initialized with.

And be sure to use a separate resistor for each LED. I am building a memory module for an 8-bit computer, and am running into an issue. What speed grade are your RAM chips, and where did you get them? Sign up or log in Sign up using Google.

Following this schematic, but using an IDT instead of stam AS6C shown The chip is receiving 5V, which is within the tolerances listed on the datasheet.
I have connected the outputs to 8 LEDs and tied all address inputs low. At first everything works as expected. So I believe what is happening here is the IDT part is sourcing much more current and burning up much more power.
