74VCXH16244 Low Voltage 16-Bit Buffer/Line Driver with Bushold
November 1999 Revised March 2002
74VCXH16244 Low Voltage 16-Bit Buffer/Line Driver with Bushold
General Description
The VCXH16244 contains sixteen non-inverting buffers with 3-STATE outputs to be employed as a memory and address driver, clock driver, or bus oriented transmitter/ receiver. The device is nibble (4-bit) controlled. Each nibble has separate 3-STATE control inputs which can be shorted together for full 16-bit operation. The VCXH16244 data inputs include active bushold circuitry, eliminating the need for external pull-up resistors to hold unused or floating data inputs at a valid logic level. The 74VCXH16244 is designed for low voltage (1.4V to 3.6V) VCC applications with output capability up to 3.6V. The 74VCXH16244 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining low CMOS power dissipation.

Functional Description
The 74VCXH16244 contains sixteen non-inverting buffers with 3-STATE outputs. The device is nibble (4 bits) controlled with each nibble functioning identically, but independent of each 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. When OEn is LOW, the outputs are in the 2-state mode. When OEn is HIGH, the standard outputs are in the high impedance mode but this does not interfere with entering new data into the inputs.

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 "Recommended Operating Conditions" table will define the conditions for actual device operation. Note 4: IO Absolute Maximum Rating must be observed. Note 5: Floating or unused control inputs must be held HIGH or LOW.
