74LVT2245 • 74LVTH2245  
Low Voltage Octal Bidirectional Transceiver with  
3-STATE Inputs/Outputs and 25: Series Resistors  
in the B Port Outputs  
General Description  
Features  
■ Input and output interface capability to systems at  
The LVT2245 and LVTH2245 contain eight non-inverting  
bidirectional buffers with 3-STATE outputs and are  
intended for bus-oriented applications. The Transmit/  
Receive (T/R) input determines the direction of data flow  
through the bidirectional transceiver. Transmit (active-  
HIGH) enables data from A Ports to B Ports; Receive  
(active-LOW) enables data from B Ports to A Ports. The  
Output Enable input, when HIGH, disables both A and B  
Ports by placing them in a high impedance state. The  
equivalent 25 -series resistor in the B Port helps reduce  
output overshoot and undershoot.  
5V VCC  
■ Equivalent 25 series resistor on B Port outputs  
■ Bushold data inputs eliminate the need for external  
pull-up resistors to hold unused inputs (74LVTH2245),  
also available without bushold feature (74LVT2245)  
■ Live insertion/extraction permitted  
■ Power Up/Down high impedance provides glitch-free  
bus loading  
■ Outputs source/sink 12 mA/ 12 mA on B Port,  
The LVTH2245 data inputs include bushold, eliminating the  
need for external pull-up resistors to hold unused inputs.  
32 mA/ 64 mA on A Port  
■ Latch-up performance exceeds 500 mA  
■ ESD performance:  
These transceivers are designed for low voltage (3.3V)  
VCC applications, but with the capability to provide a TTL  
Human-body model 2000V  
Machine model 200V  
interface to  
a 5V environment. The LVT2245 and  
LVTH2245 are fabricated with an advanced BiCMOS tech-  
nology to achieve high speed operation similar to 5V ABT  
while maintaining low power dissipation.  
Charged-device model 1000V
