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. Inputs include clamp diodes that enable the use of

current limiting resistors to interface inputs to voltages in excess of V_CC

2. Features and benefits

 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 package options

 Specified from 40 C to +85 C and from 40 C to +125 C

3. Applications

 High-speed disc or tape controller

 Communications buffer
