DESCRIPTION
The P4C1041L is a 262,144 words by 16 bits high-speed
CMOS static RAM. The CMOS memory requires no clocks
or refreshing, and has equal access and cycle times. In-
puts are fully TTL-compatible. The RAM operates from a
single 5.0V ± 10% tolerance power supply.
Access times of 55 nanoseconds permit greatly enhanced
system operating speeds. CMOS is utilized to reduce
power consumption to a low level.
The P4C1041L device provides asynchronous operation
with matching access and cycle times. Memory locations

while write enable (WE) remains HIGH. By presenting the
address under these conditions, the data in the addressed
memory location is presented on the data input/output pins.
The input/output pins stay in the HIGH Z state when either
CE or OE is HIGH or WE is LOW.
The P4C1041L comes in a 44-Pin 400 mil TSOP II pack-
age.
