Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at
www.onsemi.com.

74LCXR162245
Low Voltage 16-Bit Bidirectional Transceiver
with 5V Tolerant Inputs/Outputs
and 26: Series Resistors in the Outputs
General Description
The LCXR162245 contains sixteen non-inverting bidirec-
tional buffers with 3-STATE outputs and is intended for bus
oriented applications. The device is designed for low volt-
age (2.5V or 3.3V) V
CC
applications with capability of inter-
facing to a 5V signal environment. The device is byte
controlled. Each byte has separate control inputs which
could be shorted together for full 16-bit operation. The T/R
inputs determine the direction of data flow through the
device. The OE inputs disable both the A and B ports by
placing them in a high impedance state.
In addition, all A and B outputs include equivalent 26
:
(nominal) series resistors to reduce overshoot and under-
shoot and are designed to sink/source up to 12 mA at
V
CC
3.0V.
The LCXR162245 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
The Absolute Maximum Ratings are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated
at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the Absolute Maximum Ratings. The “Recom-
mended Operating Conditions” table will define the conditions for actual device operation.
Note 4:

Note 5:
Unused pins (Inputs or I/O's) must be held HIGH or LOW. They may not Float.
