74VCXH245  
Low Voltage Bidirectional Transceiver with Bushold  
General Description  
Features  
The VCXH245 contains eight non-inverting bidirectional  
buffers with 3-STATE outputs and is intended for bus ori-  
ented applications. The T/R input determines the direction  
of data flow. The OE input disables both the A and B Ports  
by placing them in a high impedance state. The VCXH245  
data inputs include active bushold circuitry, eliminating the  
need for external pull-up resistors to hold unused or float-  
ing data inputs at a valid logic level.  
■ 1.65V-3.6V VCC supply operation  
■ Bushold on data inputs eliminates the need for external  
pull-up/pull-down resistors  
■ tPD  
3.5 ns max for 3.0V to 3.6V VCC  
4.2 ns max for 2.3V to 2.7V VCC  
8.4 ns max for 1.65V to 1.95V VCC  
The 74VCXH245 is designed for low voltage (1.65V to  
3.6V) VCC applications.  
■ Static Drive (IOH/IOL  
)
±24 mA @ 3.0V VCC  
±18 mA @ 2.3V VCC  
± 6mA @ 1.65V VCC  
The 74VCXH245 is fabricated with an advanced CMOS  
technology to achieve high-speed operation while main-  
taining low CMOS power dissipation.  
■ Uses patented Quiet Series noise/EMI reduction  
circuitry  
■ Latchup performance exceeds 300 mA  
■ ESD performance:  
Human body model > 2000V  
Machine model > 200V
