MC74HC541A/D

MC74HC541A

Octal 3-State Non-Inverting
Buffer/Line Driver/
Line Receiver

High–Performance Silicon–Gate CMOS

The MC74HC541A 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

Maximum Input Leakage Current Vin = VCC or GND 6.0 ±0.1 ±1.0 ±1.0 µA

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.
