description  
The ’ABTE16245 devices are 16-bit (dual-octal)  
noninverting 3-state transceivers designed for  
synchronous two-way communication between  
data buses. The control-function implementation  
minimizes external timing requirements. These  
devices can be used as two 8-bit transceivers or  
2DIR  
one 16-bit transceiver. They allow data transmission from the A bus to the B bus or from the B bus to the A bus,  
depending on the logic level at the direction-control (DIR) input. The output-enable (OE) input can be used to  
disable the device so that the buses are effectively isolated. When OE is low, the device is active.  
The B port has an equivalent 25-series output resistor to reduce ringing. Active bus-hold inputs also are on  
the B port to hold unused or floating inputs at a valid logic level.  
The A port provides for the precharging of the outputs via V BIAS, which establishes a voltage between 1.3 V  
CC  
and 1.7 V when V  
is not connected.

with the bus-hold circuitry is not recommended.

stg  
Stresses beyond those listed under absolute maximum ratingsmay 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 recommended operating conditionsis not  
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.  
NOTES: 1. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.  
2. The package thermal impedance is calculated in accordance with JESD 51-7.

(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 - May not be currently available - please check http://www.ti.com/productcontent for the latest availability information and additional  
product content details.  
None: Not yet available Lead (Pb-Free).  
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" and in addition, uses package materials that do not contain halogens,  
including bromine (Br) or antimony (Sb) above 0.1% of total product weight.
