1 / 8 page © Semiconductor Components Industries, LLC, 2006 April, 2006 − Rev. 11 1 Publication Order Number: MC74HC244A/D MC74HC244A Octal 3−State Noninverting Buffer/Line Driver/ Line Receiver High−Performance Silicon−Gate CMOS The MC74HC244A is identical in pinout to the LS244. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. This octal noninverting buffer/line driver/line receiver is designed to be used with 3−state memory address drivers, clock drivers, and other bus−oriented systems. The device has noninverting outputs and two active−low output enables. The HC244A is similar in function to the HC240A. Features • Output Drive Capability: 15 LSTTL Loads • Outputs Directly Interface to CMOS, NMOS, and TTL • Operating Voltage Range: 2.0 to 6.0 V • Low Input Current: 1 mA • High Noise Immunity Characteristic of CMOS Devices • In Compliance with the Requirements Defined by JEDEC Standard No. 7A • Chip Complexity: 136 FETs or 34 Equivalent Gates • Pb−Free Packages are Available* *For additional information on our Pb−Free strategy and soldering details, please download the ON Semiconductor Soldering and Mounting Techniques Reference Manual, SOLDERRM/D. http://onsemi.com 20 1 1 20 MARKING DIAGRAMS SOIC−20 DW SUFFIX CASE 751D HC244A AWLYYWWG HC 244A ALYW G G TSSOP−20 DT SUFFIX CASE 948E SOEIAJ−20 F SUFFIX CASE 967 74HC244A AWLYWWG 1 1 1 20 1 20 20 20 See detailed ordering and shipping information in the package dimensions section on page 2 of this data sheet.
