7403 - 4-Bit x 64-word FIFO register

General Description

The 74HC/HCT7403 are high-speed Si-gate CMOS devices.

They are specified in compliance with JEDEC standard no.7A.

The “7403” is an expandable, First-In First-Out (FIFO) memory organized as 64 words by 4 bits.

Key Features

  • Synchronous or asynchronous operation.
  • 3-state outputs.
  • 30 MHz (typical) shift-in and shift-out rates.
  • Readily expandable in word and bit dimensions.
  • Pinning arranged for easy board layout: input pins directly opposite output pins.
  • Output capability: driver (8 mA).
  • ICC category: LSI.
