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