74VCX32244 Low Voltage 32-Bit Buffer/Line Driver with 3.6V Tolerant Inputs and Outputs September 2000 Revised November 2002 74VCX32244 Low Voltage 32-Bit Buffer/Line Driver with 3.6V Tolerant Inputs and Outputs General Description 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. The 74VCX32244 is designed for low voltage (1.2V 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. Features s 1.2V to 3.6V VCC supply operation s 3.6V tolerant inputs and outputs s tPD 2.5 ns max for 3.0V to 3.6V VCC s Power-off high impedance inputs and outputs s Supports live insertion and withdrawal (Note 1) s Static Drive (IOH/IOL) ±24 mA @ 3.0V VCC s Uses patented noise/EMI reduction circuitry s Latch-up performance exceeds 300 mA s ESD performance: Human body model > 2000V Machine model > 200V s 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 ……
