74ALVC2245  
Low Voltage Bidirectional Transceiver  
with 3.6V Tolerant Inputs and Outputs  
and 26Series Resistors in B Outputs  
General Description  
Features  
The ALVC2245 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.  
1.65V to 3.6V VCC supply operation  
3.6V tolerant inputs and outputs  
26series resistors in B Port outputs  
Power-off high impedance inputs and outputs  
Supports Live Insertion and Withdrawal (Note 1)  
tPD (A to B)  
The 74ALVC2245 is designed for low voltage (1.65V to  
3.6V) VCC applications with I/O compatibility up to 3.6V.  
The ALVC2245 is also designed with 26series resistance  
in the B Port outputs. This design reduces line noise in  
applications such as memory address drivers, clock driv-  
ers, and bus transceivers transmitters  
4.9 ns max for 3.0V to 3.6V VCC  
6.1 ns max for 2.3V to 2.7V VCC  
9.8 ns max for 1.65V to 1.95V VCC  
The 74ALVC2245 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 conforms to JEDEC JED78  
ESD performance:  
Human body model > 2000V  
Machine model > 200V  
Note 1: To ensure the high impedance state during power up and power  
down, OEn 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.
