description/ordering information  
The SN74CBT16811C is a high-speed TTL-compatible FET bus switch with low ON-state resistance (r ),  
on  
allowing for minimal propagation delay. Active Undershoot-Protection Circuitry on the A and B ports of the  
SN74CBT16811C provides protection for undershoot up to −2 V by sensing an undershoot event and ensuring  
that the switch remains in the proper OFF state. The device also precharges the B port to a user-selectable bias  
voltage (BIASV) to minimize live-insertion noise.  
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.

SCDS118C − JANUARY 2003 − REVISED OCTOBER 2003  
description/ordering information (continued)  
The SN74CBT16811C is organized as two 12-bit bus switches with separate output-enable (1OE, 2OE) inputs.  
It can be used as two 12-bit bus switches or as one 24-bit bus switch. When OE is low, the associated 12-bit  
bus switch is ON, and the A port is connected to the B port, allowing bidirectional data flow between ports. When  
OE is high, the associated 12-bit bus switch is OFF, and a high-impedance state exists between the A and B  
ports. The B port is precharged to BIASV through the equivalent of a 10-kresistor when OE is high, or if the  
device is powered down (V  
= 0 V).  
CC  
During insertion (or removal) of a card into (or from) an active bus, the card’s output voltage may be close to  
GND. When the connector pins make contact, the card’s parasitic capacitance tries to force the bus signal to  
GND, creating a possible glitch on the active bus. This glitching effect can be reduced by using a bus switch  
with precharged bias voltage (BIASV) of the bus switch equal to the input threshold voltage level of the receivers  
on the active bus. This method will ensure that any glitch produced by insertion (or removal) of the card will not  
cross the input threshold region of the receivers on the active bus, minimizing the effects of live-insertion noise.  
This device is fully specified for partial-power-down applications using I . The I feature ensures that  
off  
off  
damaging current will not backflow through the device when it is powered down. The device has isolation during  
power off.  
To ensure the high-impedance state during power up or power down, OE should be tied to V  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

(1) 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.  
(2)  
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.
