Revised November 2001 74ALVC162240 Low Voltage 16-Bit Inverting Buffer/Line Driver with 3.6V Tolerant Inputs and Outputs and 26Ω Series Resistors in Outputs General Description Features The ALVC162240 contains sixteen 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 74ALVC162240 is designed for low voltage (1.65V to 3.6V) VCC applications with I/O capability up to 3.6V. The 74ALVC162240 is also designed with 26Ω series resistors in the outputs. This design reduces line noise in applications such as memory address drivers, clock drivers, and bus transceivers/transmitters. The 74ALVC162240 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining low CMOS power dissipation. ■ 1.65V to 3.6V VCC supply operation ■ 3.6V tolerant inputs and outputs ■ 26Ω series resistors in outputs ■ tPD 3.8 ns max for 3.0V to 3.6V VCC 4.3 ns max for 2.3V to 2.7V VCC 7.6 ns max for 1.65V to 1.95V VCC ■ Power-off high impedance inputs and outputs ■ Supports live insertion and withdrawal (Note 1) ■ Uses patented noise/EMI reduction circuitry ■ Latchup conforms to JEDEC JED78 ■ 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.

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. The 74ALVC162240 contains sixteen 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 con- Logic Diagram www.fairchildsemi.com 2 Recommended Operating Conditions (Note 4) −0.5V to +4.6V Supply Voltage (VCC) −0.5V to 4.6V DC Input Voltage (VI) Output Voltage (VO) (Note 3) Power Supply −0.5V to VCC +0.5V Operating DC Input Diode Current (IIK) VI < 0V −50 mA 0V to VCC Output Voltage (VO) DC Output Diode Current (IOK) 0V to VCC Free Air Operating Temperature (TA) VO < 0V −50 mA −40°C to +85°C Minimum Input Edge Rate (∆t/∆V) VIN = 0.8V to 2.0V, VCC = 3.0V DC Output Source/Sink Current ±50 mA (IOH/IOL) ±100 mA Supply Pin (ICC or GND) 10 ns/V Note 2: The Absolute Maximum Ratings are those values beyond which the safety of the device cannot be guaranteed.
