Note 1: Absolute maximum ratings are values beyond which the device may be damaged or have its useful life impaired. Functional operation under these conditions is not implied.
Note 2: Either voltage limit or current limit is sufficient to protect inputs.

The 54ETL16245 contains sixteen non-inverting bidirectional buffers with TRI-STATEÉ outputs designed with incident wave switching, live insertion support and enhanced noise margin for TTL backplane applications.

Both the A and B ports of 54ETL16245 include a bus hold circuit to latch the output to the value last forced on that pin.

The B port of this 54ETL16245 includes 25X series output resistors, which minimize undershoot and ringing.
