16-Bit Registered Transceiver
Features
Functional Description
• Low power, pin-compatible replacement for LCX and
LPT families
• 5V tolerant inputs and outputs
The CY74FCT163652 is a 16-bit, high-speed, low-power,
registered transceiver that is organized as two independent
8-bit bus transceivers with three-state D-type registers and
control circuitry arranged for multiplexed transmission of data
directly from the input bus or from the internal storage
registers. OEAB and OEBA control pins are provided to control
the transceiver functions. SAB and SBA control pins are
provided to select either real-time or stored data transfer.
• 24 mA balanced drive outputs
• Power-off disable outputs permits live insertion
• Edge-rate control circuitry for reduced noise
• FCT-C speed at 4.6 ns
• Latch-up performance exceeds JEDEC standard no. 17
• ESD > 2000V per MIL-STD-883D, Method 3015
• Typical output skew < 250 ps
• Industrial temperature range of –40˚C to +85˚C
• TSSOP (19.6-mil pitch) or SSOP (25-mil pitch)
• Typical Volp (ground bounce) performance exceeds Mil
Std 883D
• VCC = 2.7V to 3.6V
Data on the A or B data bus, or both, can be stored in the
internal D flip-flops by LOW-to-HIGH transitions at the
appropriate clock pins (CLKAB or CLKBA), regardless of the
select or enable control pins. When SAB and SBA are in the
real-time transfer mode, it is also possible to store data without
using the internal D-type flip-flops by simultaneously enabling
OEAB and OEBA. In this configuration, each output reinforces
its input. Thus, when all other data sources to the two sets of
bus lines are at high impedance, each set of bus lines will
remain at its last state.
The CY74FCT163652 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 inputs
and outputs were designed to be capable of being driven by
5.0V buses, allowing them to be used in mixed voltage
systems as translators. The outputs are also designed with a
power-off disable feature enabling them to be used in
applications requiring live insertion.

Notes:
1. H = HIGH Voltage Level, L = LOW Voltage Level, X = Don’t Care,
= LOW-to-HIGH Transition
2. The data output functions may be enabled or disabled by various signals at the OEAB or OEBA 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.
3. Select control=L; clocks can occur simultaneously.
Select control=H; clocks must be staggered to load both registers.

Notes:
5. Typical values are at VCC=3.3V, +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.

Eco Plan
-
The planned eco-friendly classification: Pb-Free (RoHS) 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.
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
