CMOS STATIC RAM
FEATURES
GENERAL DESCRIPTION
• High speed access time: 45/50/70/85/100ns
The T15M256B is a low power CMOS static
RAM. organized as 32,768 x 8 bits that operates
on a single 5-volt power supply. Low operating
and standby current . Data retention is guaranteed
at a power supply voltage as low as 1.5V. This
device is packaged in a standard 28-pin
DIP(600mil), SOJ, SOP, TSOP-I forward and
reverse type.
• Low power supply current :
- Operating :37mA(max)
- Standby : 10uA
• Power supply : 5V (± 10%)
• Fully static operation – No clock or refreshing
required
• All inputs and outputs directly LVTTL
compatible
