Philips Semiconductors
9-bit bus transceiver (3-State)
Product specification
74ABT863
FEATURES
• Provides high performance bus interface buffering for wide
data/address paths or buses carrying parity
• Buffered control inputs for light loading, or increased fan-in as
required with MOS microprocessors
• Output capability: +64mA/–32mA
• Latch-up protection exceeds 500mA per Jedec Std 17
• ESD protection exceeds 2000V per MIL STD 883 Method 3015
and 200 V per Machine Model
• Power-up 3-State
• Live insertion/extraction permitted
• Inputs are disabled during 3-State mode
DESCRIPTION
The 74ABT863 bus transceiver provides high performance bus
interface buffering for wide data/address paths of buses carrying
parity.
The 74ABT863 9-bit bus transceiver has NOR-ed transmit and
receive output enables for maximum control flexibility.
