74HC/HCT7404
The 74HC/HCT7404 are high-speed Si-gate CMOS devices specified in pliance 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). With separate controls for shift-in (SI) and shift-out (SO), reading and writing operations are pletely independent, allowing synchronous and asynchronous data transfers. Additional controls include a master-reset input...
