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

This device contains protection
circuitry to guard against damage
due to high static voltages or electric
fields. 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
V

out

should be constrained to the

range GND v (Vin or V

out

) v 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.
