Hot-selling and scarce IS61C256AH-20J 32K x 8 HIGH-SPEED CMOS STATIC RAM SOJ28 spot stock

Product Descriptions

The  IS61C256AH  is  a very  high-speed,  low  power,32,768 word by 8-bit static RAMs. They are fabricated using high-performance CMOS technology. This highly reliable  process  coupled with  innovative  circuit  design  techniques, yields access times as fast as 10 ns maximum.

WhenCE is HIGH (deselected),the device assumes a standby mode at which the power dissipation can be reduced down to250 µW (typical) with CMOS input levels.

Easy memory expansion is provided by using an active LOW Chip Enable (CE)input and an active LOW Output Enable (OE) input.The active LOW Write Enable (WE)controls both writing and reading of the memory.

The IS61C256AH is pin compatible with other 32K x 8 SRAMs and are available in 28-pin PDIP, SOJ, and TSOP (Type I) packages.
