10-BIT BUFFERS/LINE DRIVERS
(WITH 3-STATE OUTPUTS)
The MC54/74F827 and MC54/74F828 10-bit bus buffers provide high per-
formance bus interface buffering for wide data/address paths or buses carry-
ing parity. The 10-bit buffers have NOR output enables for maximum control
flexibility.
The F827 and F828 are functionally and pin compatible to AMD’s 29827
and 29828. The F828 is an inverting version of the F827.
• 3-State Outputs Drive Memory Address, Bus and Clock Lines
• Outputs Sink 64 mA
• 15 mA Source Current
• Flow Through Pinout Architecture for Microprocessor Oriented
