DESCRIPTION
The
FT6116/FT6116L
are 16,384-bit ultra high-speed
static RAMs organised as 2K x 8. 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. Current drain is typically 10 µA from a 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.
The
FT6116
is available in 24-pin 300 mil DIP, SOJ and
SOIC packages, a solder seal flatpack and 4 different
LCC packages (24, 28, 32, and 40 pin).

Notes:
1. Stresses greater than those listed under MAXIMUM RATINGS may
cause permanent damage to the device. This is a stress rating only
and functional operation of the device at these or any other conditions
above those indicated in the operational sections of this specification
is not implied. Exposure to MAXIMUM rating conditions for extended
periods may affect reliability.
2. Extended temperature operation guaranteed with 400 linear feet per
minute of air flow.
3. Transient inputs with V
IL
and I
IL
not more negative than –3.0V and
–100mA, respectively, are permissible for pulse widths up to 20 ns.
