1 / 7 page © Semiconductor Components Industries, LLC, 2007 March, 2007 − Rev. 0 1 Publication Order Number: 74HC244/D 74HC244 Octal 3−State Noninverting Buffer/Line Driver/ Line Receiver High−Performance Silicon−Gate CMOS The 74HC244 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 HC244 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: 1.0 mA • High Noise Immunity Characteristic of CMOS Devices • In Compliance with the Requirements Defined by JEDEC Standard No. 7A • ESD Performance: HBM > 2000 V; Machine Model > 200 V • Chip Complexity: 136 FETs or 34 Equivalent Gates • This is a Pb−Free Device http://onsemi.com 1 20 MARKING DIAGRAM HC 244 ALYW G G TSSOP−20 DT SUFFIX CASE 948E 1 20 See detailed ordering and shipping information in the package dimensions section on page 2 of this data sheet.
