description
The CY29FCT520T is a multilevel 8-bit-wide pipeline register. The device consists of four registers, A1, A2, B1,
and B2, which are configured by the instruction inputs I0, I1 as a single four-level pipeline or as two two-level
pipelines. The contents of any register can be read at the multiplexed output at any time by using the
multiplex-selection controls (S0 and S1).
The pipeline registers are positive-edge triggered, and data is shifted by the rising edge of the clock input.
Instruction I = 0 selects the four-level pipeline mode. Instruction I = 1 selects the two-level B pipeline, while I = 2
selects the two-level A pipeline. I = 3 is the hold instruction; no shifting is performed by the clock in this mode.
In the two-level operation mode, data is shifted from level 1 to level 2 and new data is loaded into level 1.
This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs,
preventing damaging current backflow through the device when it is powered down.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

† Typical values are at VCC = 5 V, TA = 25°C.
‡ Not more than one output should be shorted at a time. Duration of short should not exceed one second. The use of high-speed test apparatus
and/or sample-and-hold techniques are preferable to minimize internal chip heating and more accurately reflect operational values. Otherwise,
prolonged shorting of a high output can raise the chip temperature well above normal and cause invalid readings in other parametric tests. In
any sequence of parameter tests, IOS tests should be performed last.

¶ This parameter is derived for use in total power-supply calculations.
# IC
= ICC + ∆ICC × DH × NT + ICCD (f0/2 + f1 × N1)
Where:
IC
= Total supply current
ICC = Power-supply current with CMOS input levels
∆ICC = Power-supply current for a TTL high input (VIN = 3.4 V)
DH
= Duty cycle for TTL inputs high
NT
= Number of TTL inputs at DH
ICCD = Dynamic current caused by an input transition pair (HLH or LHL)
f0
= Clock frequency for registered devices, otherwise zero
f1
= Input signal frequency
N1
= Number of inputs changing at f1
All currents are in milliamperes and all frequencies are in megahertz.

The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.

RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
