CY7C408A - 64 x 8 Cascadable FIFO

Download the CY7C408A datasheet PDF. This datasheet also covers the CY7C408A-15DMB variant, as both devices belong to the same 64 x 8 cascadable fifo family and are provided as variant models within a single manufacturer datasheet.

Description

The CY7C408A and CY7C409A are 64-word deep by 8- or 9-bit wide first-in first-out (FIFO) buffer memories.

In addition to the industry-standard handshaking signals, almost full/almost empty (AFE) and half-full (HF) flags are provided.

Features

  • 64 x 8 and 64 x 9 first-in first-out (FIFO) buffer memory.
  • 35-MHz shift in and shift out rates.
  • Almost Full/Almost Empty and Half Full flags.
  • Dual-port RAM architecture.
  • Fast (50-ns) bubble-through.
  • Independent asynchronous inputs and outputs.
  • Output enable (CY7C408A).
  • Expandable in word width and FIFO depth.
  • 5V ± 10% supply.
  • TTL complete.
  • Capable of withstanding greater than 2001V electro- static.
