General Description  
Features  
The MAX14548E/MAX14548AE 16-channel, bidirectional  
level translators (LLTs) provide the level shifting neces-  
sary for 100Mbps data transfer in multivoltage systems.

source, allowing both devices to be driven by either

The devices feature multiple power-saving features  
including an enable input (EN) that places the device  
into a low-power shutdown mode when driven low and  
an automatic shutdown mode that disables the part  
when V  
is less than V . The MAX14548AE output driv-
