MOTOROLA SEMICONDUCTOR TECHNICAL DATA Octal 3-State Inverting Buffer/ Line Driver/Line Receiver with LSTTL-Compatible Inputs High–Performance Silicon–Gate CMOS The MC74HCT240A is identical in pinout to the LS240. This device may be used as a level converter for interfacing TTL or NMOS outputs to High–Speed CMOS inputs. The HCT240A is an octal inverting 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 inverting outputs and two active–low output enables. The HCT240A is the inverting version of the HCT244. 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: 110 FETs or 27.5 Equivalent Gates MC74HCT240A N SUFFIX PLASTIC PACKAGE CASE 738–03 1 20 1 20 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 MC74HCTXXXAN MC74HCTXXXADW MC74HCTXXXASD MC74HCTXXXADT Plastic SOIC SSOP TSSOP LOGIC DIAGRAM A1 A2 A3 A4 DATA INPUTS B1 B2 B3 B4 2 4 6 8 11 13 15 17 18 16 14 12 9 7 5 3 YA1 YA2 YA3 YA4 YB1 YB2 YB3 YB4 INVERTING OUTPUTS PIN ASSIGNMENT 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 B……
