74VCX245  
Low Voltage Bidirectional Transceiver  
with 3.6V Tolerant Inputs and Outputs  
General Description  
Features  
■ 1.4V to 3.6V VCC supply operation  
The VCX245 contains eight non-inverting bidirectional buff-  
ers with 3-STATE outputs and is intended for bus oriented  
applications. The T/R input determines the direction of data  
flow. The OE input disables both the A and B ports by plac-  
ing them in a high impedance state.  
■ 3.6V tolerant inputs and outputs  
■ Power-off high impedance inputs and outputs  
■ Supports Live Insertion and Withdrawal (Note 1)  
■ tPD  
The 74VCX245 is designed for low voltage (1.4V to 3.6V)  
VCC applications with I/O compatibility up to 3.6V.  
3.5 ns max for 3.0V to 3.6V VCC  
The 74VCX245 is fabricated with an advanced CMOS  
technology to achieve high-speed operation while main-  
taining low CMOS power dissipation.  
■ Static Drive (IOH/IOL  
)
24 mA @ 3.0V VCC  
■ Uses patented noise/EMI reduction  
circuitry  
■ Latchup performance exceeds 300 mA  
■ ESD performance:  
Human body model 2000V  
Machine model 200V  
■ Leadless DQFN Pb-Free package  
Note 1: To ensure the high impedance state during power up and power  
down, OE should be tied to V  
through a pull up resistor. The minimum  
CC  
n
value of the resistor is determined by the current sourcing capability of the  
driver.
