74LCXZ16240
Low Voltage 16-Bit Inverting Buffer/Line Driver with
5V Tolerant Inputs/Outputs (Preliminary)
General Description
The LCXZ16240 contains sixteen inverting buffers with 3-
STATE outputs designed to be employed as a memory and
address driver, clock driver, or bus-oriented transmitter/
receiver. The device is nibble controlled. Each nibble has
separate 3-STATE control inputs which can be shorted
together for full 16-bit operation.
When VCC is between 0 and 1.5V, the LCXZ16240 is in the
high impedance state during power up or power down. This
places the outputs in the high impedance (Z) state prevent-
ing intermittent low impedance loading or glitching in bus
oriented applications.
The LCXZ16240 is designed for low voltage (2.7V or 3.3V)
VCC applications with capacity of interfacing to a 5V signal
environment.
The LCXZ16240 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing CMOS low power dissipation.

Functional Description
The LCXZ16240 contains sixteen inverting buffers with 3-
STATE standard outputs. The device is nibble (4 bits) con-
trolled with each nibble functioning identically, but indepen-
dent of the other. The control pins may be shorted together
to obtain full 16-bit operation. The 3-STATE outputs are
controlled by an Output Enable (OEn) input for each nibble.
When OEn is LOW, the outputs are in 2-state mode. When
OEn is HIGH, the outputs are in the high impedance mode,
but this does not interfere with entering new data into the
inputs.

Note 1: 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 2: IO Absolute Maximum Rating must be observed.
Note 3: Unused inputs must be held HIGH or LOW. They may not float.
