Overview
HM-6561/883 March 1997 256 x 4 CMOS RAM Description The HM-6561/883 is a 256 x 4 static CMOS RAM fabricated using self-aligned silicon gate technology.
Synchronous circuit design techniques are employed to achieve high performance and low power operation.
On-chip latches are provided for address and data outputs allowing efficient interfacing with microprocessor systems.
The data output buffers can be forced to a high impedance state for use in expanded memory arrays.
The data inputs and outputs are multiplexed internally for common I/O bus compatibility.
The HM-6561/883 is a fully static RAM and may be maintained in any state for an indefinite period of time.
Data retention supply voltage and supply current are guaranteed over temperature.
Features • This Circuit is Processed in Accordance to MIL-STD883 and is Fully Conformant Under the Provisions of Paragraph 1.
