1 / 9 page Rev.3.00, Jul.16.2004, page 1 of 8 HD74BC244A Octal Buffers/Line Drivers With 3 State Outputs REJ03D0281–0300Z (Previous ADE-205-007A (Z)) Rev.3.00 Jul.16.2004 Description The HD74BC244A 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. This device is a non inverting buffer and has two active low enables (1 G and 2G). Each enable independently controls 4 buffers. 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. • TTL level input • Wide operating temperature range Ta = –40 to + 85°C • Ordering Information Part Name Package Type Package Code Package Abbreviation Taping Abbreviation (Quantity) HD74BC244AP DILP-20 pin DP-20N, -20NEV P — HD74BC244AFPEL SOP-20 pin (JEITA) FP-20DAV FP EL (2,000 pcs/reel) HD74BC244ATELL TSSOP-20 pin TTP-20DAV T ELL (2,000 pcs/reel) Note: Please consults the sales office for the above package availability.
