74ETL16245 - 16-Bit Data Transceiver

Datasheet Summary

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

Features

Y Supports the VME64 ETL specification Y Functionally and pin compatible with industry standard TTL 16245 SSOP pinout Y Improved TTL-compatible input threshold range Y High drive TTL-compatible outputs (IOH e b60 mA IOL e 90 mA) Y Supports 25X incident wave switching on the A port Y BiCMOS design significantly reduces power dissipation Y Distributed VCC and GND pin configuration minimizes high-speed switching noise Y 25X series-dampening resistor on B-port Y Available in 48-pin SSOP and ceramic.
