40821 General Description

The IDT7014 is a high-speed 4K x 9 Dual-Port Static RAM designed to be used in systems where on-chip hardware port arbitration is not needed. This part lends itself to high-speed applications which do not rely on BUSY signals to manage simultaneous access. The IDT7014 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. See functional description.

The IDT7014 utilitizes a 9-bit wide data path to allow for parity at the user's option. This feature is especially useful in data communication applications where it is necessary to use a parity bit for transmission/ reception error checking. Fabricated using IDT's high-performance technology, these Dual- Ports typically operate on only 750mW of power at maximum access times as fast as 12ns. The IDT7014 is packaged in a 52-pin PLCC and a 64-pin thin quad flatpack, (TQFP).

40821 Maximum Ratings

Symbol	Rating	Com'l & Ind'l	Unit	Military
V_TERM	Terminal Voltage with respect to GND	-0.5 to +7.0	V	-0.5 to +7.0
T_STG	Temperature Under Bias	-0.5 to +VCC	°C	-65 to +135
T_STG	Storage Temperature	-55 to +125	mA	-65 to +150
I_OUT	DC Output Current	50	mA	50

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 this 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%.
