Octal 3-State Buffer/Line Driver IC - 74HC541

The 74HC Series 74HC541 IC is an octal non-inverting buffer/line driver with 3-state outputs. The device features two output enables (OE1 and OE2). A HIGH on OEn causes the outputs to assume a high-impedance OFF-state.

Inputs include clamp diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of VCC.

1.What is 74HC541?

  • The 74HC541 is a non-inverting octal buffer/line driver with three output states. The device has two output options (OE1 and OE2). When OEn is HIGH, the outputs go into a high-impedance OFF state.

2.Can the 74HC541 IC be used to interface with TTL logic?

  • Yes, the 74HC541 IC is TTL logic level compatible and can interface with both TTL and CMOS circuits. The 74HC541 IC's 3-state output feature allows the outputs to be disabled or set to a high-impedance state, effectively disconnecting them from the circuit. This feature can be used to prevent signal interference and to connect multiple devices to the same output line.
