IDT71V428L

www.DataSheet4U.com 3.3V CMOS Static RAM 4 Meg (1M x 4-Bit) IDT71V428S IDT71V428L Features ◆ ◆ ◆ Description The IDT71V428 is a 4,194,304-bit high-speed Static RAM organized as 1M x 4. It is fabricated using IDT’s high-perfomance, highreliability CMOS technology. This state-of-the-art technology, combined with innovative circuit design techniques, provides a costeffective solution for high-speed memory needs. The IDT71V428 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 IDT71V428 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 IDT71V428 is packaged in a 32-pin, 400 mil Plastic SOJ. ◆ ◆ ◆ ◆ ◆ 1M x 4 advanced high-speed CMOS Static RAM JEDEC Center Power / GND pinout for reduced noise Equal access and cycle times — Commercial and Industrial: 10/12/15ns Single 3.3V power supply One Chip Select plus one Output Enable pin Bidirectional data inputs and outputs directly LVTTL-compatible Low power consumption via chip deselect Available in 32-pin, 400 mil plastic SOJ package.
