CY74FCT162646T
16-Bit Registered Transceivers
SCCS060B - August 1994 - Revised September 2001

packages

• VCC = 5V ± 10%
CY74FCT16646T Features:
• 64 mA sink current, 32 mA source current
• Typical VOLP (ground bounce) <1.0V at VCC = 5V,
TA = 25˚C
CY74FCT162646T Features:

The CY74FCT16646T and CY74FCT162646T 16-bit
transceivers are three-state, D-type registers, and control
circuitry arranged for multiplexed transmission of data directly
from the input bus or from the internal registers. Data on the A
or B bus will be clocked into the registers as the appropriate
clock pin goes to a HIGH logic level. Output Enable (OE) and
direction pins (DIR) are provided to control the transceiver
function. In the transceiver mode, data present at the high
impedance port may be stored in either the A or B register, or
in both. The select controls can multiplex stored and real-time
(transparent mode) data. The direction control determines
which bus will receive data when the Output Enable (OE) is
Active LOW. In the isolation mode (Output Enable (OE) HIGH),
A data may be stored in the B register and/or B data may be
stored in the A register.
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.
The CY74FCT16646T is ideally suited for driving
high-capacitance loads and low-impedance backplanes.
The CY74FCT162646T has 24-mA balanced output drivers
with current limiting resistors in the outputs. This reduces the
need for external terminating resistors and provides for
minimal undershoot and reduced ground bounce. The
CY74FCT162646T is ideal for driving transmission lines.

The data output functions may be enabled or disabled by various signals at the OE or DIR inputs. Data input functions are always enabled, i.e., data at the
bus pins will be stored on every LOW-to-HIGH transition on the clock inputs.
Cannot transfer data to A-bus and B-bus simultaneously.

Notes:
4. Stresses greater than those listed under Maximum Ratings may cause permanent damage to the device. This is a stress rating only and functional operation
of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect reliability.
5. Typical values are at VCC= 5.0V, TA= +25˚C ambient.
6. This parameter is specified but not tested.
7. 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 in order to minimize internal chip heating and more accurately reflect operational values. Otherwise prolonged shorting of
a high output may raise the chip temperature well above normal and thereby cause invalid readings in other parametrics tests. In any sequence of parameter
tests, IOS tests should be performed last.
8. This parameter is measured at characterization but not tested.
9. Tested at +25˚C.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS
compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
(3)
MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder
temperature.
