DESCRIPTION
❑ Four 8-bit Registers
❑ Implements Double 2-Stage Pipeline
or Single 4-Stage Pipeline Register
❑ Hold, Shift, and Load Instructions
❑ Separate Data In and Data Out Pins
❑ High-Speed, Low Power CMOS
Technology
❑ Three-State Outputs
❑ Replaces IDT29FCT520/IDT29FCT521
and AMD Am29520/Am29521
❑ Package Styles Available:
• 24-pin PDIP
• 28-pin PLCC, J-Lead
The L29C520 and L29C521 are pinfor-pin compatible with the
IDT29FCT520/IDT29FCT521 and
AMD Am29520/Am29521, implemented in low power CMOS.
The L29C520 and L29C521 contain
four registers which can be configured
as two independent, 2-level pipelines
or as one 4-level pipeline.
The Instruction pins, I1-0, control the
loading of the registers. For either
device, the registers may be configured as a four-stage delay line, with
data loaded into R1 and shifted
sequentially through R2, R3, and R4.
Also, for the L29C520, data may be
loaded from the inputs into either R1
or R3 with only R2 or R4 shifting. The
L29C521 differs from the L29C520 in
that R2 and R4 remain unchanged
during this type of data load, as
shown in Tables 1 and 2. Finally, I1-0
may be set to prevent any register
from changing.
L29C520/521 BLOCK DIAGRAM
The S1-0 select lines control a 4-to-1
multiplexer which routes the contents
of any of the registers to the Y output
pins. The independence of the I and S
controls allows simultaneous write
and read operations on different
registers.

1. Maximum Ratings indicate stress
specifications only. Functional operation of these products at values beyond
those indicated in the Operating Conditions table is not implied. Exposure to
maximum rating conditions for extended periods may affect reliability.
9. AC specifications are tested with
input transition times less than 3 ns,
output reference levels of 1.5 V (except
tDIS test), and input levels of nominally
0 to 3.0 V. Output loading may be a

the transition is measured to the
±200mV level from the measured
steady-state output voltage with
±10mA loads. The balancing voltage, V TH , is set at 3.5 V for Z-to-0
and 0-to-Z tests, and set at 0 V for Zto-1 and 1-to-Z tests.

the high temperature extreme, which is
the worst case for leakage current.

imum or maximum value. Input requirements are specified from the point
of view of the external system driving
the chip. Setup time, for example, is
specified as a minimum since the external system must supply at least that
much time to meet the worst-case requirements of all parts. Responses from
the internal circuitry are specified from
the point of view of the device. Output
delay, for example, is specified as a
maximum since worst-case operation of
any device always provides data within
that time.
