General Description

The 54 74ETL16245 contains sixteen non-inverting bidirectional buffers with TRI-STATE outputs designed with incident wave switching live insertion support and enhanced noise margin for TTL backplane applications Both the A and B ports include a bus hold circuit to latch the output to the value last forced on that pin The B port of this device includes 25X series output resistors which minimize undershoot and ringing

Overview

54 74ETL16245 16-Bit Data Transceiver with Incident Wave Switching PRELIMINARY May 1994 54 74ETL16245 16-Bit Data Transceiver with Incident Wave Switching.

Key Features
