MOTOROLA SEMICONDUCTOR TECHNICAL DATA Octal 3-State Noninverting Buffer/Line Driver/ Line Receiver High–Performance Silicon–Gate CMOS The MC54/74HC244A 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 and HC241A. Output Drive Capability: 15 LSTTL Loads Outputs Directly Interface to CMOS, NMOS, and TTL Operating Voltage Range: 2 to 6 V Low Input Current: 1 A 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 MC54/74HC244A J SUFFIX CERAMIC PACKAGE CASE 732–03 1 20 20 1 20 1 N SUFFIX PLASTIC PACKAGE CASE 738–03 DW SUFFIX SOIC PACKAGE CASE 751D–04 SD SUFFIX SSOP PACKAGE CASE 940C–03 DT SUFFIX TSSOP PACKAGE CASE 948E–02 20 1 20 1 ORDERING INFORMATION Ceramic MC54HCXXXAJ Plastic MC74HCXXXAN SOIC MC74HCXXXADW SSOP MC74HCXXXASD TSSOP MC74HCXXXADT LOGIC DIAGRAM 2 4 6 8 11 13 15 17 18 16 14 12 9 7 5 3 A1 A2 A3 A4 DATA INPUTS B1 B2 B3 B4 YA1 YA2 YA3 YA4 YB1 YB2 YB3 YB4 NONINVERTING OUTPUTS PIN ASSIGNMENT ENABLE A A1 YB4 A2 YB3 A3 YB2 A4 YB1 GND 1 2 3 4 5 6 7 8 9 10……
