IDT71016
Description
64K x 16 advanced high-speed CMOS Static RAM
Equal access and cycle times
– Commercial and Industrial: 12/15/20ns
One Chip Select plus one Output Enable pin
Bidirectional data inputs and outputs directly TTLcompatible
Low power consumption via chip deselect
Upper and Lower Byte Enable Pins
Commercial and industrial product available in 44-pin
Plastic SOJ package and 44-pin TSOP package
The IDT71016 is a 1,048,576-bit high-speed Static RAM organized
as 64K 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
high-speed memory needs.
The IDT71016 has an output enable pin which operates as fast as 7ns,
with address access times as fast as 12ns. All bidirectional inputs and
outputs of the IDT71016 are TTL-compatible and operation is from a single
5V supply. Fully static asynchronous circuitry is used, requiring no clocks
or refresh for operation.
The IDT71016 is packaged in a JEDEC standard 44-pin Plastic SOJ
and 44-pin TSOP Type II.

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 + 0.5V.

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 t WHZ + 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.
