CMOS PARALLEL FIFO

64 x 4-BIT AND 64 x 5-BIT

Integrated Device Technology, Inc.

Output Enable (OE) pin. The FlFOs accept 4-bit or 5-bit data

at the data input (D0-D3, 4). The stored data stack up on a first-

in/first-out basis.

FEATURES:

• First-ln/First-Out Dual-Port memory

• 64 x 4 organization (IDT72401/03)

• 64 x 5 organization (IDT72402/04)

• IDT72401/02 pin and functionally compatible with

MMI67401/02

• RAM-based FIFO with low falI-through time

• Low-power consumption

— Active: 175mW (typ.)

A Shift Out (SO) signal causes the data at the next to last

word to be shifted to the output while all other data shifts down

one location in the stack. The Input Ready (IR) signal acts like

a flag to indicate when the input is ready for new data

(IR = HIGH) or to signal when the FIFO is full (IR = LOW). The

Input Ready signal can also be used to cascade multiple

devices together. The Output Ready (OR) signal is a flag to

indicate that the output remains valid data (OR = HIGH) or to

indicate that the FIFO is empty (OR = LOW). The Output

Readycanalsobeusedtocascademultipledevicestogether.

Width expansion is accomplished by logically ANDing the

Input Ready (IR) and Output Ready (OR) signals to form

composite signals.

• Maximum shift rate — 45MHz

• High data output drive capability

• Asynchronous and simultaneous read and write

• Fully expandable by bit width

• Fully expandable by word depth

• IDT72403/04 have Output Enable pin to enable output

data

Depth expansion is accomplished by tying the data inputs

of one device to the data outputs of the previous device. The

Input Ready pin of the receiving device is connected to the

Shift Out pin of the sending device and the Output Ready pin

of the sending device is connected to the Shift In pin of the

receiving device.

Reading and writing operations are completely asynchro-

nous allowing the FIFO to be used as a buffer between two

digital machines of widely varying operating frequencies. The

45MHz speed makes these FlFOs ideal for high-speed

communication and controller applications.

• High-speed data communications applications

• High-performance CMOS technology

• Available in CERDIP, plastic DIP and SOIC

• Military product compliant to MlL-STD-883, Class B

• Standard Military Drawing #5962-86846 and

5962-89523 is listed on this function.

• Industrial temperature range (–40°C to +85°C) is avail-

able, tested to military electrical specifications

DESCRIPTION:

The IDT72401 and IDT72403 are asynchronous high-

performance First-ln/First-Out memories organized 64 words

by 4 bits. The IDT72402 and IDT72404 are asynchronous

high-performance First-ln/First-Out memories organized as

64 words by 5 bits. The IDT72403 and IDT72404 also have an

Military grade product is manufactured in compliance with

the latest revision of MIL-STD-883, Class B.
