74VCX32245 Datasheet | Fairchild Semiconductor

Description The VCX32245 contains thirty-two non-inverting bidirectional buffers with 3-STATE outputs and is intended for bus oriented applications. The device is byte controlled. Each byte has separate 3-STATE control inputs which can be shorted together for full 32-bit operation. The T/R inputs determine the direction of data flow through the device. The OE inputs disable both the A and B ports by placing them in a high impedance state. The 74VCX32245 is designed for low voltage (1.65V to 3.6V) VCC applications with I/O patibility up to 3.6V. The 74VCX32245 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining low CMOS power dissipation. Features s 1.65V- 3.6V VCC supply operation s 3.6V tolerant inputs and outputs s t PD 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 s Power-down high impedance inputs and outputs s Supports live insertion/withdrawal (Note 1) s Static Drive (IOH/IOL) ±24 m A @ 3.0V VCC ±18 m A @ 2.3V VCC ±6 m A @ 1.65V VCC s Uses patented noise/EMI reduction circuitry s Latchup performance exceeds 300 m A s ESD performance: Human body model > 2000V Machine model >200V s Packaged 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.
