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) 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 26
: series
resistors
s 5.3 ns tPD max (VCC 3.3V), 20 PA ICC max
s Power down high impedance inputs and outputs
s Supports live insertion/withdrawal (Note 1)
s Flow through pinout
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.
