70914

Obsolete

4K x 9 Sync, Dual-Port RAM, Flow-Through

Overview

The 70914 is a high-speed 4K x 9 bit synchronous Dual-Port RAM that has been optimized for applications having unidirectional data flow or bi-directional data flow in bursts. The 70914 utilizes a 9-bit wide data path to allow for parity which is useful in data communication applications where it is necessary to use a parity bit for transmission/ reception error checking. An automatic power down feature, controlled by CE, permits the on-chip circuitry of each port to enter a very low standby power mode.
