DESCRIPTION:
The IDT723613 is a monolithic, high-speed, low-power, BiCMOS synchronous (clocked) FIFO memory which supports clock frequencies up to 67 MHz and has read-access times as fast as 10 ns.

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 FIFO buffering data from Port A
   to Port B
• Mailbox bypass registers in each direction
• Dynamic Port B bus sizing of 36-bits (long word), 18-bits
   (word), and 9-bits (byte)
• Selection of Big- or Little-Endian format for word and byte
   bus sizes
• Three modes of byte-order swapping on Port B
• Programmable Almost-Full and Almost-Empty flags
• Microprocessor interface control logic
• FF, AF flags synchronized by CLKA
• EF, AE flags synchronized by CLKB
• Passive parity checking on each Port
• Parity Generation can be selected for each Port
• Low-power advanced BiCMOS technology
• Supports clock frequencies up to 67 MHz
• Fast access times of 10 ns
• Available in 132-pin quad flatpack (PQF) or space-saving
   120-pin thin quad flatpack (TQFP)
• Industrial temperature range (-40°C to +85°C) is available,
   tested to military electrical specifications
