Description
The IDT7132/IDT7142 are high-speed 2K x 8 Dual-Port Static RAMs.
The IDT7132 is designed to be used as a stand-alone 8-bit Dual-Port RAM
or as a “MASTER” Dual-Port RAM together with the IDT7142 “SLAVE”
Dual-Port in 16-bit-or-more word width systems. Using the IDT MASTER/
SLAVE Dual-Port RAM approach in 16-or-more-bit memory system
applications results in full-speed, error-free operation without the need for
additional discrete logic.
Both devices provide two independent ports with separate control,
address, and l/O pins that permit independent, asynchronous access for
reads or writes to any location in memory. 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 CMOS high-performance technology, these
devices typically operate on only 325mW of power. Low-power (LA)
versions offer battery backup data retention capability, with each Dual-
Port typically consuming 200µW from a 2V battery.
The IDT7132/7142 devices are packaged in a 48-pin sidebraze or
plastic DIPs, 48-pin LCCs, 52-pin PLCCs, and 48-lead flatpacks.
Military grade product is manufactured in compliance with the latest
revision of MIL-PRF-38535 QML, making it ideally suited to military
temperature applications demanding the highest level of performance
and reliability.

(TA = +25°C,f = 1.0MHz)
NOTES:
1. This parameter is determined by device characterization but is not production
tested.
2. 3dV represents the interpolated capacitance when the input and output signals
switch from 3V to 0V.

NOTES:
1. Stresses greater than those listed under ABSOLUTE 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 the specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect reliability.
2. VTERM must not exceed Vcc + 10% for more than 25% of the cycle time or 10ns
maximum, and is limited to < 20mA for the period of VTERM > Vcc + 10%.
NOTES:
1. This is the parameter TA. This is the "instant on" case temperature.
2. Industrial temperature: for specific speeds, packages and powers contact your
sales office.
NOTES:
1. VIL (min.) = -1.5V for pulse width less than 10ns.
2. VTERM must not exceed Vcc + 10%.
NOTES:
1. All VCC pins must be connected to the power supply.
2. All GND pins must be connected to the ground supply.
3. Package body is approximately .75 in x .75 in x .17 in.
