Octal 3-State Non-Inverting

Buffer/Line Driver/

Line Receiver With

LSTTL-Compatible Inputs

High–Performance Silicon–Gate CMOS

The MC74HCT541A is identical in pinout to the LS541. This device may

be used as a level converter for interfacing TTL or NMOS outputs to high

speed CMOS inputs.

The HCT541A 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.

• 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 5.5V

• Low Input Current: 1µA

• In Compliance With the JEDEC Standard No. 7A Requirements

• Chip Complexity: 134 FETs or 33.5 Equivalent Gates
