DESCRIPTION
The P4C164 and P4C164L are 65,536-bit ultra high-speed
static RAMs organized as 8K 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.
With battery backup, 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 10 nanoseconds are available,
permitting greatly enhanced system operating speeds. In
full standby mode with CMOS inputs, power consumption
is only 5.5 mW for the P4C164L.
The P4C164 and P4C164L are available in 28-pin 300 mil
DIP and SOJ, 28-pin 600 mil ceramic DIP, and 28-pin 350
x 550 mil LCC packages providing excellent board level
densities.

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.
4. This parameter is sampled and not 100% tested.
