DESCRIPTION:

• 3.3V family uses less power than the 5 Volt 7201/7202/7203/7204/

7205/7206family

• 512 x 9 organization (72V01)

• 1,024 x 9 organization (72V02)

• 2,048 x 9 organization (72V03)

• 4,096 X 9 organization (72V04)

• 8,192 x 9 organization (72V05)

• 16,384 X 9 organization (72V06)

• Functionally compatible with 720x family

• Low-power consumption

— Active: 180 mW (max.)

— Power-down: 18 mW (max.)

• 15 ns access time

• Asynchronous and simultaneous read and write

• Fully expandable by both word depth and/or bit width

• Status Flags: Empty, Half-Full, Full

• Auto-retransmit capability

The IDT72V01/72V02/72V03/72V04/72V05/72V06 are dual-port FIFO
