IDT72261LA/72271LA SuperSync FIFO
16,384 x 9 and 32,768 x 9
NOTES:
1. Use an AND gate in IDT Standard mode, an OR gate in FWFT mode.
2. Do not connect any output control signals directly together.
3. FIFO #1 and FIFO #2 must be the same depth, but may be different word widths.
OPTIONALCONFIGURATIONS
WIDTH EXPANSION CONFIGURATION
Word width may be increased simply by connecting together the control
signalsofmultipledevices. Statusflagscanbedetectedfromanyonedevice.
The exceptions are the EF and FF functions in IDT Standard mode and the
IR andOR functions in FWFT mode. Because of variations in skew between
RCLK and WCLK, it is possible for EF/FF deassertion and IR/OR assertion
to vary by one cycle between FIFOs. In IDT Standard mode, such problems

Figure 21 demonstrates a width expansion using two IDT72261LA/
72271LA devices. D0 - D8 from each device form a 18-bit wide input bus and
Q0-Q8 from each device form a 18-bit wide output bus. Any word width can
be attained by adding additional IDT72261LA/72271LA devices.
