1 / 6 page MOTOROLA SEMICONDUCTOR TECHNICAL DATA 3–1 REV 1 © Motorola, Inc. 1995 10/95 Octal 3-State Non-Inverting Buffer/Line Driver/ Line Receiver High–Performance Silicon–Gate CMOS The MC54/74HC541A is identical in pinout to the LS541. The device inputs are compatible with Standard CMOS outputs. External pullup resistors make them compatible with LSTTL outputs. The HC541A is an octal non–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 HC541A is similar in function to the HC540A, which has 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: 1µA • High Noise Immunity Characteristic of CMOS Devices • In Compliance With the JEDEC Standard No. 7A Requirements • Chip Complexity: 134 FETs or 33.5 Equivalent Gates 18 Y1 2 A1 17 Y2 3 A2 16 Y3 4 A3 15 Y4 5 A4 14 Y5 6 A5 13 Y6 7 A6 12 Y7 8 A7 11 Y8 9 A8 OE1 OE2 1 19 Output Enables Data Inputs Non–Inverting Outputs PIN 20 = VCC PIN 10 = GND LOGIC DIAGRAM Pinout: 20–Lead Packages (Top View) 19 20 18 17 16 15 14 2 1 3 4 5 6 7 VCC 13 8 12 9 11 10 OE2 Y1 Y2 Y3 Y4 Y5 Y6 Y7 Y8 OE1 A1 A2 A3 A4 A5 A6 A7 A8 GND L L H X L L X H L H X X MC54/74HC541A FUNCTION TABLE Inputs Output Y OE1 OE2 A L H Z Z Z = High Impedance X = Don’t Care DW SUFFIX SOIC PACKAGE CASE 751D–04 N SUFFIX PLASTIC PACKAGE CASE 738–03 ORDERING INFORMATION MC54HCXXXAJ MC74HCXXXAN MC74HCXXXADW Ceramic Plastic SOIC J SUFFIX CERAMIC PACKAGE CASE 732–03 1 20 1 20 1 20 |
