IDT71V416VL15Y

Memory IC Overview

The IDT71V416VL15Y is a 4 Megabit (256K x 16) high-speed CMOS Static RAM. It operates on a single 3.3V supply and features LVTTL-compatible bidirectional data inputs and outputs. The device utilizes fully static asynchronous circuitry, eliminating the need for clocks or refresh cycles. It offers an address access time of 15 nanoseconds with equal read and write cycle times. The component is housed in a 44-pin, 400-mil plastic SOJ package and supports commercial temperature ranges.
