MOTOROLA SEMICONDUCTOR TECHNICAL DATA Octal 3-State Inverting Buffer/ Line Driver/Line Receiver High–Performance Silicon–Gate CMOS The MC74HC540A is identical in pinout to the LS540. The device inputs are compatible with Standard CMOS outputs. External pullup resistors make them compatible with LSTTL outputs. The HC540A 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. This device features inputs and outputs on opposite sides of the package and two ANDed active–low output enables. The HC540A is similar in function to the HC541A, which has non–inverting outputs. Output Drive Capability: 15 LSTTL Loads Outputs Directly Interface to CMOS, NMOS and TTL Operating Voltage Range: 2 to 6V Low Input Current: 1A High Noise Immunity Characteristic of CMOS Devices In Compliance With the JEDEC Standard No. 7A Requirements Chip Complexity: 124 FETs or 31 Equivalent Gates LOGIC DIAGRAM 20 MC74HC540A N SUFFIX PLASTIC PACKAGE CASE 738–03 1 20 1 DW SUFFIX SOIC PACKAGE CASE 751D–04 ORDERING INFORMATION MC74HCXXXAN MC74HCXXXADW Plastic SOIC FUNCTION TABLE Inputs Output Y OE1 OE2 L L X H A L H X X H L Z Z A1 A2 A3 A4 A5 A6 A7 A8 Output Enables OE1 OE2 2 3 4 5 6 7 8 9 1 19 18 17 16 15 14 13 12 11 Y1 Y2 Y3 Y4 Y5 Y6 Y7 Y8 L L H X Z = High Impedance X = Don’t Care Inverting Outputs Data Inputs PIN 20 = VCC PIN 10 = GND Pinout: 20–Lead Packages (Top View) VCC 20 OE2 19 Y1……
