74LCXR162245
Low Voltage 16-Bit Bidirectional Transceiver with 5V
Tolerant Inputs/Outputs and 26Series 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) VCC 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
VCC = 3.0V.
The LCXR162245 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing CMOS low power dissipation.
Features
s 5V tolerant inputs and outputs
s 2.3V–3.6V VCC specifications provided
s A and B side outputs have equivalent 26series
resistors
s 5.3 ns tPD max (VCC = 3.3V), 20 µA ICC max
s Power down high impedance inputs and outputs
s Supports live insertion/withdrawal (Note 1)
s Flow through pinout
s Implements patented noise/EMI reduction circuitry
s Latch-up performance exceeds 500 mA
s ESD performance:
Human body model > 2000V
Machine model > 200V
Note 1: To ensure the high-impedance state during power up or down OE
should be tied to VCC through a pull-up resistor: the minimum value or the
resistor is determined by the current-sourcing capability of the driver.

Note 3: 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: IO Absolute Maximum Rating must be observed.
Note 5: Unused pins (Inputs or I/O's) must be held HIGH or LOW. They may not Float.
