GENERAL DESCRIPTION

The 74HC/HCT7404 are high-speed Si-gate CMOS devices specified in compliance with JEDEC standard no.7A.

The “7404” is an expandable, First-In First-Out (FIFO) memory organized as 64 words by 5 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

• 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.

APPLICATIONS

• High-speed disc or tape controller

• Communications buffer.
