GENERAL DESCRIPTION
The MT5C6408, 8K x 8 SRAM, employs high-speed,
low-power CMOS technology, eliminating the need for clocks
or refreshing. These SRAM’s have equal access and cycle
times.
For flexibility in high-speed memory applications,
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.
Writing to these devices is accomplished when write
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.
These devices operate from a single +5V power sup-
ply and all inputs and outputs are fully TTL compatible.
