HM-6561/883

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-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 per-

formance and low power operation.

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

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

• Fast Access Time. . . . . . . . . . . . . . . . . . . . . . 200ns Max

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

• TTL Compatible Input/Output

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.

• High Output Drive - 1 TTL Load

• On-Chip Address Registers

• Common Data In/Out

• Three-State Output

• Easy Microprocessor Interfacing
