Description
74HC7403; 74HCT7403 4-bit x 64-word FIFO register; 3-state Rev.4 * 24 September 2012 Product data sheet 1.General .
The 74HC7403; 74HCT7403 is an expandable, First-In First-Out (FIFO) memory organized as 64 words by 4 bits.
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 74HC
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 incl
