Features
Description
◆
The IDT71V416 is a 4,194,304-bit high-speed Static RAM organized
as 256K x 16. It is fabricated using IDT’s high-perfomance, high-reliability
CMOS technology. This state-of-the-art technology, combined with innovative circuit design techniques, provides a cost-effective solution for highspeed memory needs.
The IDT71V416 has an output enable pin which operates as fast as
5ns, with address access times as fast as 10ns. All bidirectional inputs and
outputs of the IDT71V416 are LVTTL-compatible and operation is from a
single 3.3V supply. Fully static asynchronous circuitry is used, requiring
no clocks or refresh for operation.
The IDT71V416 is packaged in a 44-pin, 400 mil Plastic SOJ and a
44-pin, 400 mil TSOP Type II package and a 48 ball grid array, 9mm x
9mm package.

NOTES:
1. A write occurs during the overlap of a LOW CS, LOW BHE or BLE, and a LOW WE.
2. OE is continuously HIGH. If during a WE controlled write cycle OE is LOW, tWP must be greater than or equal to tWHZ + tDW to allow the I/O drivers to turn off and data
to be placed on the bus for the required tDW. If OE is HIGH during a WE controlled write cycle, this requirement does not apply and the minimum write pulse is as
short as the specified tWP.
3. During this period, I/O pins are in the output state, and input signals must not be applied.
4. If the CS LOW or BHE and BLE LOW transition occurs simultaneously with or after the WE LOW transition, the outputs remain in a high-impedance state.
5. Transition is measured ±200mV from steady state.
