DESCRIPTION

The

FT61981/L

and

FT61982/L

are 65,536-bit (16Kx4)

ultra high-speed static RAMs similar to the

FT6198,

but

with separate data I/O pins. The

FT61981/L

feature a

transparent write operation when

is low; the outputs

of the

FT61982/L

are in high impedance during the write

cycle. All devices have low power standby modes. The

RAMs operate from a single 5V ± 10% tolerance power

supply. With battery backup, data integrity is maintained

for supply voltages down to 2.0V. Current drain is

typically 10 µA from 2.0V supply.

Access times as fast as 10 nanoseconds are available,

permitting greatly enhanced system operating speeds.

CMOS is used to reduce power consumption. For the

FT61982L

and

FT61981L,

power is only 5.5 mW standby

with CMOS input levels.

The

FT61981/L

and

FT61982/L

are available in 28-pin 300

mil DIP and SOJ, 28-pin 350x550 mil LCC and a 28-pin

CERPACK package providing excellent board level den-

sities.
