Revised August 2001 74VCX32244 Low Voltage 32-Bit Buffer/Line Driver with 3.6V Tolerant Inputs and Outputs General Description Features The VCX32244 contains thirty-two 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 8-bit, 16-bit or full 32-bit operation. ■ 1.65V–3.6V VCC supply operation The 74VCX32244 is designed for low voltage (1.65V to 3.6V) VCC applications with I/O capability up to 3.6V. The 74VCX32244 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining low CMOS power dissipation. ■ 3.6V tolerant inputs and outputs ■ tPD 2.5 ns max for 3.0V to 3.6V VCC 3.0 ns max for 2.3V to 2.7V VCC 6.0 ns max for 1.65V to 1.95V VCC ■ Power-off high impedance inputs and outputs ■ Supports live insertion and withdrawal (Note 1) ■ Static Drive (IOH/IOL) ±24 mA @ 3.0V VCC ±18 mA @ 2.3V VCC ±6 mA @ 1.8V VCC ■ Uses patented noise/EMI reduction circuitry ■ Latch-up performance exceeds 300 mA ■ ESD performance: Human body model > 2000V Machine model > 200V ■ Packages in plastic Fine-Pitch Ball Grid Array (FBGA) 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 74VCX32244 contains thirty-two 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 32-bit operation.The 3-STATE out- Logic Diagrams Byte 1 Byte 2 Byte 3 Byte 4 Note: Please note that these diagrams are provided only for the understanding of logic operations and should not be used to estimate propagation delays. 3 www.fairchildsemi.com 74VCX32244 Functional Description 74VCX32244 Absolute Maximum Ratings(Note 3) Supply Voltage (VCC ) −0.5V to +4.6V DC Input Voltage (VI) −0.5V to +4.6V Recommended Operating Conditions (Note 5) Power Supply Output Voltage (VO) Operating −0.5V to +4.6V Outputs 3-STATED Outputs Active (Note 4) DC Input Diode Current (IIK) VI < 0V 1.65V to 3.6V Data Retention Only −0.5V to VCC +0.5V −50 mA Output Voltage (VO) VO < 0V −50 mA Output in 3-State VO > VCC +50 mA DC Output Diode Current (IOK) Output in Active States ±50 mA Storage Temperature Range (TSTG) VCC = 3.0V to 3.6V ±24 mA VCC = 2.3V to 2.7V ±18 mA VCC = 1.65V to 2.3V DC VCC or GND Current per Supply Pin (ICC or GND) 0V to VCC 0.0V to 3.6V Output Current in IOH/IOL DC Output Source/Sink Current (IOH/IOL) 1.2V to 3.6V −0.3V to +3.6V Input Voltage ±100 mA ±6 mA Free Air Operating Temperature (TA) −65°C to +150 °C −40°C to +85°C Minimum Input Edge Rate (∆t/∆V) VIN = 0.8V to 2.0V, VCC = 3.0V 10 ns/V Note 3: The Absolute Maximum Ratings are those values beyond which the safety of the device cannot be guaranteed.
