| 3.3V CMOS STATIC RAM 4 MEG (256K x 16-BIT) Integrated Device Technology, Inc. ADVANCE INFORMATION IDT71V416 FEATURES: * 256K x 16 advanced high-speed CMOS Static RAM * JEDEC Center Power /GND pinout for reduced noise * Equal access and cycle times -- 12/15/20ns * Single 3.3V power supply * One Chip Select plus one Output Enable pin * Bidirectional data inputs and outputs directly TTL-compatible * Low power consumption via chip deselect * Upper and Lower Byte Enable Pins * Available in 44-pin, 400 mil plastic SOJ package DESCRIPTION: The IDT71V416 is a 4,194,304-bit high-speed Static RAM organized as 256K x 16. It is fabricated using IDT's highperfomance, high-reliability CMOS technology. This state-ofthe-art technology, combined with innovative circuit design techniques, provides a cost-effective solution for high-speed memory needs. The IDT71V416 has an output enable pin which operates as fast as 6ns, with address access times as fast as 12ns. All bidirectional inputs and outputs of the IDT71V416 are TTLcompatible 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, 400mil Plastic SOJ.
