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.

Increase the current limit the Sran or remove them, yeah its cool to see the data go by but useless and the problem in all likelihood will go away.
I have observed this behavior with all 3 IDT chips I ordered. Better still, use another buffer to drive the LEDs. Eli Lorden 12 2.

I have connected the outputs to 8 LEDs and tied all address inputs low. An LED’s IV curve is exponential, so if you give it a little more voltage, you get a lot more current. Home Questions Tags Users Unanswered. 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 my part. What speed grade are your RAM chips, and where did you get them?
At first everything works as expected. The chip is receiving 5V, which is within the tolerances listed on the datasheet.
And be sure to use a separate resistor for each LED. Sign up using Email and Password.
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. Email Required, but never shown. I can view each byte of junk data the SRAM has been initialized with.

I am sraj 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. What value is the LED current-limiting resistor?

So typically the output voltage of the IDT could be higher. So I believe what is happening here is the IDT part is sourcing much more current and burning up much more power. Sign up using Facebook.
