Philips Semiconductors
Bus transceivers (3-State)
Product specification
74F862, 74F863
FEATURES
• Provide high performance bus interface buffering for wide
data/address paths or buses carrying parity
• High impedance NPN base inputs for reduced loading (20µA in
High and Low states)
• IIL is 20µA vs. 1000µA for AM29861 series
• Buffered control inputs for light loading, or increased fan-in as
required with MOS microprocessors
• Positive and negative over-shoots are clamped to ground
• 3-State outputs glitch free during power-up and power-down
• Slim dual In-line (DIP) 300mil package
• Broadside pinout compatible with AMD AM29862–29863
• Outputs sink 64mA
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.
