www.DataSheet4U–.co8m3 mW Standby (CMOS Input) P4C168
Single 5V±10% Power Supply
DESCRIPTION
The P4C168, P4C169 and P4C170 are a family of
16,384-bit ultra high-speed static RAMs organized as 4K
x 4. All three devices have common input/output ports.The
P4C168 enters the standby mode when the chip enable
(CE) control goes HIGH; with CMOS input levels, power
consumption is only 83mW in this mode. Both the P4C169
and the P4C170 offer a fast chip select access time that
is only 67% of the address access time. In addition, the
P4C170 includes an output enable (OE) control to elimi-
nate data bus contention. The RAMs operate from a
single 5V ± 10% tolerance power supply.
FUNCTIONAL BLOCK DIAGRAM
Fully TTL Compatible, Common I/O Ports
Three Options
– P4C168 Low Power Standby Mode
– P4C169 Fast Chip Select Control
– P4C170 Fast Chip Select, Output Enable
Controls
Standard Pinout (JEDEC Approved)
– P4C168: 20-pin DIP, SOJ, LCC, SOIC,
CERPACK, and Flat Pack
– P4C169: 20-pin DIP and SOIC
– P4C170: 22-pin DIP
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 P4C168 and P4C169 are available in 20-pin (P4C170
in 22-pin) 300 mil DIP packages providing excellent
board level densities. The P4C168 is also available in 20-
pin 300 mil SOIC, SOJ, CERPACK, and Flat Pack
packages.
The P4C169 is also available in a 20-pin 300 mil SOIC
package.
