Overview

The µPD485505 is a 5,048 words by 8 bits high speed FIFO (First In First Out) line buffer. Its CMOS static circuitry provides high speed access and low power consumption.

  • 5,048 words by 8 bits
  • Asynchronous read/write operations available
  • Variable length delay bits; 21 to 5,048 bits (Cycle time: 25 ns) 15 to 5,048 bits (Cycle time: 35 ns)
  • Power supply voltage VCC = 5.0 V ± 0.5 V
  • Suitable for sampling one line of A3 size paper (16 dots/mm)
  • All input/output TTL compatible
  • 3-state output
  • Full static operation; data hold time = infinity
