74HCT7403 - 4-bit x 64-word FIFO register

Download the 74HCT7403 datasheet PDF. This datasheet also covers the 74HC7403 variant, as both devices belong to the same 4-bit x 64-word fifo register family and are provided as variant models within a single manufacturer datasheet.

Description

The 74HC7403; 74HCT7403 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).

Features

  • Synchronous or asynchronous operation.
  • 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.
  • Input levels:.
  • For 74HC7403: CMOS level.
  • For 74HCT7403: TTL level.
  • 3-state outputs.
  • Complies with JEDEC standard JESD7A.
  • ESD protection:.
  • HBM JESD22-A114F exceeds 2 000 V.
  • MM JESD22-A115-A exceeds 200 V.
  • Multiple packag.

74HC7403; 74HCT7403 4-bit x 64-word FIFO register; 3-state Rev. 4 — 24 September 2012 Product data sheet 1. General description The 74HC7403; 74HCT7403 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.
