74ALVC16240 Low Voltage 16-Bit Inverting Buffer/Line Driver with 3.6V Tolerant Inputs and Outputs October 2001 Revised May 2005 74ALVC16240 Low Voltage 16-Bit Inverting Buffer/Line Driver with 3.6V Tolerant Inputs and Outputs General Description The ALVC16240 contains sixteen inverting buffers with 3STATE 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 74ALVC16240 is designed for low voltage (1.65V to 3.6V) VCC applications with I/O capability up to 3.6V. The 74ALVC16240 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining low CMOS power dissipation. Features s 1.65V to 3.6V VCC supply operation s 3.6V tolerant inputs and outputs s tPD 3.0 ns max for 3.0V to 3.6V VCC 3.5 ns max for 2.3V to 2.7V VCC 6.0 ns max for 1.65V to 1.95V VCC s Power-off high impedance inputs and outputs s Supports live insertion and withdrawal (Note 1) s Uses patented noise/EMI reduction circuitry s Latchup conforms to JEDEC JED78 s ESD performance: Human body model ! 2000V Machine model ! 200V Note 1: To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pull-up resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.

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.
