74ALVCH245  
Low Voltage Bidirectional Transceiver with Bushold  
General Description  
Features  
The ALVCH245 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 ALVCH245  
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 to 3.6V VCC supply operation  
Bushold on data inputs eliminates the need for external  
pull-up/pull-down resistors  
tPD  
3.6 ns max for 3.0V to 3.6V VCC  
4.2 ns max for 2.3V to 2.7V VCC  
6 ns max for 1.65V to 1.95V VCC  
The 74ALVCH245 is designed for low voltage (1.65V to  
3.6V) VCC applications.  
Uses patented Quiet Series noise/EMI reduction  
circuitry  
The 74ALVCH245 is fabricated with an advanced CMOS  
technology to achieve high-speed operation while main-  
taining low CMOS power dissipation.  
Latchup conforms to JEDEC JED78

Human body model > 2000V  
Machine model > 200V
