GENERAL DESCRIPTION
The MT5C1001 employs low power, high-performance
silicon-gate CMOS technology. Static design eliminates the
need for external clocks or timing strobes while CMOS circuitry
reduces power consumption and provides for greater
reliability.
For flexibility in high-speed memory applications, ASI
offers chip enable (CE\) and output enable (OE\) capability.
These enhancements can place the outputs in High-Z for addi-
tional flexibility in system design. Writing to these devices is
accomplished when write enable (WE|) and CE\ inputs are both
LOW. Reading is accomplished when WE\ remains HIGH while
CE\ and OE\ go LOW. The devices offer a reduced power
standby mode when disabled. This allows system designs to
achieve low standby power requirements.
The 鈥淟鈥?version provides an approximate 50 percent
reduction in CMOS standby current (I
SBC2
) over the standard
version.
All devices operation from a single +5V power supply
and all inputs and outputs are fully TTL compatible.
