LH540205 - CMOS 8192 x 9 Asynchronous FIFO

General Description

The LH540205 is a FIFO (First-In, First-Out) memory device, based on fully-static CMOS dual-port SRAM technology, capable of storing up to 8192 nine-bit words.

It follows the industry-standard architecture and package pinouts for nine-bit asynchronous FIFOs.

Key Features

  • Fast Access Times: 20/25/35/50 ns.
  • Fast-Fall-Through Time Architecture Based on CMOS Dual-Port SRAM Technology.
  • Input Port and Output Port Have Entirely Independent Timing.
  • Expandable in Width and Depth.
  • Full, Half-Full, and Empty Status Flags.
  • Data Retransmission Capability.
  • TTL-Compatible I/O.
  • Pin and Functionally Compatible with Am/IDT7205.
  • Control Signals Assertive-LOW for Noise Immunity.
  • Package: 28-P.
