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 patible with industry standard
TTL 16245 SSOP pinout
Y Improved TTL-patible input threshold range
Y High drive TTL-patible outputs (IOH e b60 m A IOL e 90 m A)
Y Supports 25X incident wave switching on the A port
Y Bi CMOS 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 flatpak
Y Guaranteed output skew
Y Guaranteed simultaneous switching noise level and dynamic threshold performance
Y Guaranteed latchup protection
