DESCRIPTION

The

FT6198/L

and

FT6198A/L

are 65,536-bit ultra high-

speed static RAMs organized as 16K x 4. Each device

features an active low Output Enable control to eliminate

data bus contention. The

FT6198/L

also have an active

low Chip Enable (the

FT6198A/L

have two Chip Enables,

both active low) for easy system expansion. The CMOS

memories require no clocks or refreshing and have equal

access and cycle times. Inputs are fully TTL-compatible.

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

power supply. Data integrity is maintained with supply

voltages down to 2.0V. Current drain is typically 10

µA

from a 2.0V supply.

Access times as fast as 12 nanoseconds are available,

permitting greatly enhanced system operating speeds.

CMOS is used to reduce power consumption to a low 715

mW active, 193 mW standby.

The

FT6198/L

and

FT6198A/L

are available in 24-pin

300 mil DIP and SOJ, and 28-pin 350 x 550 mil LCC

packages providing excellent board level densities.
