HM1-6551B/883

Manufacturer Part Number
HM1-6551B/883
Description
256 x 4 CMOS RAM
Manufacturer
Intersil Corporation
Datasheet
256 x 4 CMOS RAM
The HM-6551/883 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 HM-6551/883 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.
