Fully asynchronous operation from either port
Battery backup operation—2V data retention
TTL-compatible; single 5V (
±
10%) power supply
Available in several popular hermetic and plastic packages
Military product compliant to MIL-STD-883, Class B
Industrial temperature range (–40
°
C to +85
°
C) is available
for selected speeds
to those systems which cannot tolerate wait states or are
designed to be able to externally arbitrate or withstand
contention when both sides simultaneously access the same
Dual-Port RAM location.
The IDT7134 provides two independent ports with separate
control, address, and I/O pins that permit independent,
asynchronous access for reads or writes to any location in
memory. It is the user’s responsibility to ensure data integrity
when simultaneously accessing the same memory location
from both ports. An automatic power down feature, controlled
by
CE
, permits the on-chip circuitry of each port to enter a very
low standby power mode.
Fabricated using IDT’s CMOS high-performance
technology, these Dual-Port typically on only 700mW of
power. Low-power (LA) versions offer battery backup data
retention capability, with each port typically consuming 200
μ
W
from a 2V battery.
The IDT7134 is packaged on either a sidebraze or plastic
48-pin DIP, 48-pin LCC, 52-pin PLCC and 48-pin Flatpack.
Military grade product is manufactured in compliance with the
latest revision of MIL-STD-883, Class B, making it ideally
suited to military temperature applications demanding the
highest level of performance and reliability.

DESCRIPTION:
The IDT7134 is an extremely high-speed 4K x 8 Dual-Port
Static RAM designed to be used in systems where on-chip
hardware port arbitration is not needed. This part lends itself
