DESCRIPTION:
The IDT723611 is a monolithic, high-speed, low-power, CMOS Synchronous (clocked) FIFO memory which supports clock frequencies up to 67MHz and has read access times as fast as 10ns.
   
FEATURES:
• Free-running CLKA and CLKB may be asynchronous or
    coincident (permits simultaneous reading and writing of
    data on a single clock edge)
• 64 x 36 storage capacity
• Synchronous data buffering from Port A to Port B
• Mailbox bypass register in each direction
• Programmable Almost-Full (AF) and Almost-Empty (AE)
    flags
• Microprocessor Interface Control Logic
• Full Flag (FF) and Almost-Full (AF) flags synchronized by
    CLKA
• Empty Flag (EF) and Almost-Empty (AE) flags synchronized by CLKB
• Passive parity checking on each Port
• Parity Generation can be selected for each Port
• Supports clock frequencies up to 67MHz
• Fast access times of 10ns
• Available in 132-pin Plastic Quad Flatpack (PQF) or
    space-saving 120-pin Thin Quad Flatpack (PF)
• Low-power advanced CMOS technology
• Industrial temperature range (-40oC to +85oC) is available,
    tested to military elecrical specifications
