CBT3245A  
Octal bus switch  
Rev. 3 — 5 January 2012  
Product data sheet  
1. General description  
The CBT3245A provides eight bits of high-speed TTL-compatible bus switching. The low  
ON resistance of the switch allows connections to be made with minimal propagation  
delay.  
The CBT3245A is organized as one 8-bit bus switches with one output enable (OE) input.  
When OE is LOW, the switch is on and port A is connected to the B port. When OE is  
HIGH, each switch is disabled. The CBT3245A is characterized for operation from 40 C  
to +85 C.  
2. Features and benefits  
5 switch connection between two ports  
TTL-compatible control input levels  
Multiple package options  
Latch-up protection exceeds 500 mA per JESD78  
ESD protection:  
HBM JESD22-A114F exceeds 2000 V  
MM JESD22-A115B exceeds 150 V  
CDM JESD22-C101C exceeds 1000 V

(1) This is not a supply pin. The substrate is attached to this pad using conductive die attach material. There is no electrical or  
mechanical requirement to solder this pad. However, if it is soldered, the solder land should remain floating or be connected to

[1] Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the  
device at these or any other conditions beyond those indicated under Section 8. is not implied. Exposure to absolute-maximum-rated  
conditions for extended periods may affect device reliability.  
[2] The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.  
8. Recommended operating conditions

[1] All typical values are at VCC = 5 V, Tamb = 25 C.  
[2] This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND.  
[3] Measured by the voltage drop between the An and the Bn terminals at the indicated current through the switch. ON resistance is  
determined by the lowest voltage of the two (An or Bn) terminals.

All input pulses are supplied by generators having the following characteristics: PRR 10 MHz; Zo = 50 .  
The outputs are measured one at a time with one transition per measurement.  
Definitions for test circuit:  
RL = Load resistance.  
CL = Load capacitance including jig and probe capacitance.  
RT = Termination resistance should be equal to output impedance Zo of the pulse generator.

The term ‘short data sheet’ is explained in section “Definitions”.  
The product status of device(s) described in this document may have changed since this document was published and may differ in case of multiple devices. The latest product status  
information is available on the Internet at URL http://www.nexperia.com.  
Suitability for use — Nexperia products are not designed,  
16.2 Definitions  
authorized or warranted to be suitable for use in life support, life-critical or  
safety-critical systems or equipment, nor in applications where failure or  
malfunction of a Nexperia product can reasonably be expected  
to result in personal injury, death or severe property or environmental  
damage. Nexperia and its suppliers accept no liability for  
inclusion and/or use of Nexperia products in such equipment or

representations or warranties as to the accuracy or completeness of  
information included herein and shall have no liability for the consequences of  
use of such information.  
Short data sheet — A short data sheet is an extract from a full data sheet  
with the same product type number(s) and title. A short data sheet is intended  
for quick reference only and should not be relied upon to contain detailed and  
full information. For detailed and full information see the relevant full data  
sheet, which is available on request via the local Nexperia sales

Applications — Applications that are described herein for any of these  
products are for illustrative purposes only. Nexperia makes no  
representation or warranty that such applications will be suitable for the  
specified use without further testing or modification.  
Customers are responsible for the design and operation of their applications  
and products using Nexperia products, and Nexperia  
accepts no liability for any assistance with applications or customer product  
design. It is customer’s sole responsibility to determine whether the Nexperia  
product is suitable and fit for the customer’s applications and  
products planned, as well as for the planned application and use of  
customer’s third party customer(s). Customers should provide appropriate  
design and operating safeguards to minimize the risks associated with their  
applications and products.  
Product specification — The information and data provided in a Product  
data sheet shall define the specification of the product as agreed between  
Nexperia and its customer, unless Nexperia and  
customer have explicitly agreed otherwise in writing. In no event however,  
shall an agreement be valid in which the Nexperia product is  
deemed to offer functions and qualities beyond those described in the  
Product data sheet.  
Nexperia does not accept any liability related to any default,  
damage, costs or problem which is based on any weakness or default in the  
customer’s applications or products, or the application or use by customer’s

the products or of the application or use by customer’s third party  
customer(s). Nexperia does not accept any liability in this respect.  
Limiting values — Stress above one or more limiting values (as defined in  
the Absolute Maximum Ratings System of IEC 60134) will cause permanent  
damage to the device. Limiting values are stress ratings only and (proper)  
operation of the device at these or any other conditions above those given in  
the Recommended operating conditions section (if present) or the  
Characteristics sections of this document is not warranted. Constant or  
repeated exposure to limiting values will permanently and irreversibly affect  
the quality and reliability of the device.  
In no event shall Nexperia be liable for any indirect, incidental,  
punitive, special or consequential damages (including - without limitation - lost  
profits, lost savings, business interruption, costs related to the removal or  
replacement of any products or rework charges) whether or not such  
damages are based on tort (including negligence), warranty, breach of  
contract or any other legal theory.  
Terms and conditions of commercial sale — Nexperia  
products are sold subject to the general terms and conditions of commercial  
sale, as published at http://www.nexperia.com/profile/terms, unless otherwise  
agreed in a valid written individual agreement. In case an individual  
agreement is concluded only the terms and conditions of the respective  
agreement shall apply. Nexperia hereby expressly objects to  
applying the customer’s general terms and conditions with regard to the  
purchase of Nexperia products by customer.  
Notwithstanding any damages that customer might incur for any reason
