Overview

66 CY7C164 CY7C166 16K x 4 Static RAM.

Key Features

  • High speed.
  • 15 ns.
  • Output enable (OE) feature (CY7C166).
  • CMOS for optimum speed/power.
  • Low active power.
  • 633 mW.
  • Low standby power.
  • 110 mW.
  • TTL-compatible inputs and outputs.
  • Automatic power-down when deselected three-state drivers. The CY7C166 has an active LOW Output Enable (OE) feature. Both devices have an automatic powerdown feature, reducing the power consumption by 65% when deselected. Writing to th.
