HD74BC540A Octal Buffers/Line Drivers With 3 State Outputs REJ03D0285–0200Z (Previous ADE-205-031 (Z)) Rev.2.00 Jul.16.2004 Description The HD74BC540A provides high drivability and operation equal to or better than high speed bipolar standard logic IC by using Bi-CMOS process. The device features low power dissipation that is about 1/5 of high speed bipolar logic IC, when the frequency is 10 MHz. The device has eight inverter drivers with three state outputs in a 20 pin package. When G1 and G2 is low level, this drivers set up output is enable. Features Input/Output are at high impedance state when power supply is off. Built in input pull up circuit can make input pins be open, when not used. Input is TTL level. Wide operating temperature range Ta = –40 to +85°C Ordering Information Part Name HD74BC540AFPEL Package Type Package Code Package Abbreviation SOP-20 pin (JEITA) FP-20DAV FP Taping Abbreviation (Quantity) EL (2,000 pcs/reel) Function Table ...
