GENERAL DESCRIPTION
low-power CMOS technology, eliminating the need for clocks
or refreshing. These SRAM’s have equal access and cycle
times.
Austin Semiconductor offers dual chip enables (CE1\, CE2) and
output enable (OE\) capability. These enhancements can place
the outputs in High-Z for additional flexibility in system design.
enable (WE\) and CE1\ inputs are both LOW and CE2 is HIGH.
Reading is accomplished when WE\ and CE2 remain HIGH and
CE1\ and OE\ go LOW. The device offers a reduced power
standby mode when disabled. This allows system designs to
achieve low standby power requirements.
ply and all inputs and outputs are fully TTL compatible.
