DESCRIPTION
The 74F862 and 74F863 bus transceivers provide high performance bus interface buffering for wide data/address paths of buses carrying parity. The 74F863 9-bit bus transceiver has NOR-ed transmit and receive output enables for maximum control flexibility. TYPICAL PROPAGATION DELAY 6.0ns 6.0ns TYPICAL SUPPLY CURRENT (TOTAL) 150mA 115mA
NOTE: 1. Thermal mounting techniques are recommended. See SMD Process Applications for a discussion of thermal considerations for surface mounted devices.
