HM-6551/883

256 x 4 CMOS RAM

March 1997

Features

Description

• This Circuit is Processed in Accordance to MIL-STD-

883 and is Fully Conformant Under the Provisions of

Paragraph 1.2.1.

The HM-6551/883 is a 256 x 4 static CMOS RAM fabricated

using self-aligned silicon gate technology. Synchronous cir-

cuit design techniques are employed to achieve high perfor-

mance 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.

• Low Power Standby. . . . . . . . . . . . . . . . . . . . 50µW Max

• Low Power Operation . . . . . . . . . . . . . 20mW/MHz Max

• Fast Access Time. . . . . . . . . . . . . . . . . . . . . . 220ns Max

• Data Retention . . . . . . . . . . . . . . . . . . . . . . . .at 2.0V Min

• TTL Compatible Input/Output

The HM-6551/883 is a fully static RAM and may be main-

tained in any state for an indeﬁnite period of time. Data

retention supply voltage and supply current are guaranteed

over temperature.

• High Output Drive - 1 TTL Load

• Internal Latched Chip Select

• High Noise Immunity

• On-Chip Address Register

• Latched Outputs

• Three-State Output
