74VCX32245
Low Voltage 32-Bit Bidirectional Transceiver
with 3.6V Tolerant Inputs and Outputs (Preliminary)
General Description
The VCX32245 contains thirty-two non-inverting bidirec-
tional 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 compatibility up to 3.6V.
The 74VCX32245 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing low CMOS power dissipation.
Features
s 1.65V–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
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 mA @ 3.0V VCC
±18 mA @ 2.3V VCC
±6 mA @ 1.65V VCC
s Uses patented noise/EMI reduction circuitry
s Latchup performance exceeds 300 mA
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.
