The units are well-suited for Address buffers on the MC6800 or similar microprocessor application. | e e | © High Speed — 8.0 ns (Typ? | 1 : © Three-State Logic Configuration L SUFFIX P SUFFIX ® Single +5 V Power Supply Requirement CERAMIC PACKAGE PLASTIC PACKAGE © Compatible with 74LS Logic or MC6800 Microprocessor Systems CASE 620 CASE 648 © High impedence PNP Inputs Assure Minimal Loading of the Bus _ INPUT EQUIVALENT CIRCUIT | vec | MICROPROCESSOR BUS EXTENDER APPLICATION (Clock) ONO ss ot a2 | a OJ“ ‘M6800 ¥ | meu OUTPUT EQUIVALENT CIRCUIT 7 over ‘MCBTS7/MC5887 (MCBT26A/MCBB90 -7 werreuMeas | ; ‘BUS EXTENDER iL BUS EXTENDER < b 4 wei : | ADDRESS: ROMs DATA 1 ane crc, *| a j conto were BUS ‘RAMs r crit "| Y | cain t a a | C1 ‘ORDERING INFORMATION wes [——} (Temperature Range = Oto + 75°C) ACIAS [eee — Package ~wcaTs7 mice. “Caramic DIE ee a 0 oss | wcorere [cease | Plate DAA [-Mestsse | mceaaar [Plastic 6°] MOTOROLA LINEAR/INTERFACE ICs DEVICE DATA 7-33
