MOTOROLA SEMICONDUCTOR TECHNICAL DATA Octal 3-State Noninverting Buffer/Line Driver/ Line Receiver with LSTTL-Compatible Inputs High-Performance Silicon-Gate CMOS The MC54/74HCT244A is identical in pinout to the LS244. This device may be used as a level converter for interfacing TTL or NMOS outputs to High-Speed CMOS inputs. The HCT244A is an octal noninverting buffer line driver line receiver designed to be used with 3-state memory address drivers, clock drivers, and other bus-oriented systems. The device has non-inverted outputs and two active-low output enables. The HCT244A is the noninverting version of the HCT240. See also HCT241. * * * * * * Output Drive Capability: 15 LSTTL Loads TTL NMOS-Compatible Input Levels Outputs Directly Interface to CMOS, NMOS, and TTL Operating Voltage Range: 4.5 to 5.5 V Low Input Current: 1 A In Compliance with the Requirements Defined by JEDEC Standard No. 7A * Chip Complexity: 112 FETs or 28 Equivalent Gates MC54/74HCT244A 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 MC54HCTXXXAJ Ceramic MC74HCTXXXAN Plastic MC74HCTXXXADW SOIC MC74HCTXXXASD SSOP MC74HCTXXXADT TSSOP LOGIC DIAGRAM PIN ASSIGNMENT A1 A2 A3 A4 DATA INPUTS B1 B2 B3 B4 11 13 15 17 9 7 5 3 YB1 YB2 YB3 YB4 2 4 6 8 18 16 14 12 YA1 YA2 YA3 YA4 NONINVERTING OUTPUTS ENABLE A A1 YB4 A2 YB3 A3 YB2 A4 YB1 GND 1 2 3 4 5 6 7 8 9 10 20 19 18 17 16 15 14 13 12 11 VCC ENABLE B YA1 B4 YA2 B3 YA3 B2 YA4 B1 FUNCTION TABLE Inputs Outputs YA, YB L H Z Enable A, Enable B L L H 1 OUTPUT ENABLE A ENABLES ENABLE B 19 PIN 20 = VCC PIN 10 = GND A, B L H X Z = high impedance X = don't care 10/95 (c) Motorola, Inc. 1995 1 REV 6 IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I III I I I I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I III I I I I I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII II I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I IIIIIIIIIIIIIIIIIIIIIIIII II I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII IIIIIII I I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIIIIIIIIIII II I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I II I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I III I I I IIIIIIIIIIIIIIIIIIIIIII I III I I I I IIIIIIIIIIIIIIIIIIIIIII I I IIIIIIIIIIIIIIIIIIIIIII III I III I I III I IIIIIIIIIIIIIIIIIIIIIII III I IIIIIIIIIIIIIIIIIIIIIII III I IIIIIIIIIIIIIIIIIIIIIII III I IIIIIIIIIIIIIIIIIIIIIII III I IIIIIIIIIIIIIIIIIIIIIII III I IIIIIIIIIIIIIIIIIIIIIII III I IIIIIIIIIIIIIIIIIIIIIII III I IIIIIIIIIIIIIIIIIIIIIII III I IIIIIIIIIIIIIIIIIIIIIII III I IIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIII II I IIIIIIIIIIIIIIIIIIIIIII III I IIIIIIIIIIIIIIIIIIIIIII III I IIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIII II I IIIIIIIIIIIIIIIIIIIIIII III I IIIIIIIIIIIIIIIIIIIIIII III I * Maximum Ratings are those values beyond which damage to the device may occur.

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, Vin and Vout should be constrained to the range GND (Vin or Vout) VCC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused outputs must be left open.
