E/–MAX3012  
General Description  
Features  
The MAX3000E/MAX3001E/MAX3002–MAX3012  
8-channel level translators provide the level shifting nec-  
essary to allow data transfer in a multivoltage system.  
Guaranteed Data Rate Options  
230kbps (MAX3000E)  
4Mbps (MAX3001E)  
20Mbps (MAX3002–MAX3012)  
Externally applied voltages, V and V , set the logic lev-  
CC  
L
els on either side of the device. Logic signals present on  
Bidirectional Level Translation Without Using a  
Directional Pin (MAX3000E/MAX3001E/MAX3002/  
MAX3003)  
the V side of the device appear as a higher voltage logic  
L
signal on the V side of the device, and vice-versa.  
CC  
The MAX3000E/MAX3001E/MAX3002/MAX3003 use an  
architecture specifically designed to be bidirectional  
without the use of a directional pin.

also have 1ꢀ5V EꢁS protection on the ꢂ/ꢃ V  
side for  
CC  
greater protection in applications that route signals  
externally. The MAX3000E operates at a guaranteed data  
rate of 2305bps. The MAX3001E operates at a guaranteed  
data rate of 4Mbps. The MAX3002–MAX3012 operate at a  
guaranteed data rate of 20Mbps over the entire specified  
operating voltage range.
