74LCXZ16245
Low Voltage 16-Bit Bidirectional Transceiver
with 5V Tolerant Inputs and Outputs
General Description
The LCXZ16245 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 (2.7V 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.
When VCC is between 0V and 1.5V, the LCXZ16245 is on
the high impedance state during power-up or power-down.
This places the outputs in the high impedance (Z) state
preventing intermittent low impedance loading or glitching
in bus oriented applications.
The LCXZ16245 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 2.7V–3.6V VCC specifications provided
s 4.5 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 ±24 mA output drive (VCC = 3.0V)
s Implements patented noise/EMI reduction circuitry
s Latch-up performance conforms to the requirements of
JESD78
s ESD performance:
Human body model > 2000V
Machine model > 200V
s Also packaged in plastic Fine-Pitch Ball Grid Array
(FBGA) (Preliminary)
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 Conditionstable will define the conditions for actual device operation.
Note 4: IO Absolute Maximum Rating must be observed.
Note 5: Unused inputs or I/O's must be held HIGH or LOW. They may not float.
