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. A guaranteed 15 MHz data-rate makes it ideal for high-speed applications. A higher data-rate can be obtained in applications where the status flags are not used (burst-mode).

With separate controls for shift-in (SI) and shift-out (SO), reading and writing operations are completely independent, allowing synchronous and asynchronous data transfers. Additional controls include a master-reset input (MR), an output enable input (OE) and flags. The data-in-ready (DIR) and data-out-ready (DOR) flags indicate the status of the device.

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.
