10-BIT BUFFERS/LINE DRIVERS (WITH 3-STATE OUTPUTS) The MC54/74F827 and MC54/74F828 10-bit bus buffers provide high performance bus interface buffering for wide data/address paths or buses carrying 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 Applications CONNECTION DIAGRAMS (TOP VIEW) VCC O0 24 23 O1 22 O2 21 O3 20 O4 19 O5 18 O6 17 O7 16 O8 15 O9 OE2 14 13 24 MC54/74F827 MC54/74F828 10-BIT BUFFERS/LINE DRIVERS (WITH 3-STATE OUTPUTS) FAST SCHOTTKY TTL 24 1 J SUFFIX CERAMIC CASE 758-01 1 N SUFFIX PLASTIC CASE 724-03 F827 1 OE1 2 D0 3 D1 O1 22 4 D2 O2 21 5 D3 O3 20 6 D4 O4 19 7 D5 O5 18 8 D6 O6 17 9 D7 O7 16 10 D8 O8 15 11 12 D9 GND O9 OE2 14 13 24 1 DW SUFFIX SOIC CASE 751E-03 VCC O0 24 23 ORDERING INFORMATION MC54FXXXJ Ceramic MC74FXXXN Plastic MC74FXXXDW SOIC F828 LOGIC SYMBOL 1 OE1 2 D0 3 D1 4 D2 5 D3 6 D4 7 D5 8 D6 9 D7 10 D8 11 12 D9 GND 1 13 F827 2 3 4 5 6 7 8 9 10 11 D6 D7 D8 D9 LOGIC DIAGRAM D0 D1 D2 D3 D4 D5 OE1 OE2 O0 O1 O2 O3 O4 O5 O6 O7 O8 O9 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0 23 22 21 20 19 18 17 16 15 14 F828 2 3 4 5 6 OE1 OE2 O9 O8 O7 O6 O5 O4 O3 O2 O1 O0 1 13 7 8 9 10 11 Please note that this diagram is ……
