The MC74HCT541N is an octal buffer/line driver with 3-state outputs manufactured by Freescale Semiconductor - NXP. This device is part of the HCT family of high-speed CMOS logic and offers TTL-compatible input thresholds, low power consumption, and high noise immunity. It is typically used to amplify signals or isolate sections of a circuit.
Applications
- Bus drivers
- Line drivers
- Memory address drivers
- Clock drivers

- Octal Buffer: Buffers eight signals simultaneously.
- 3-State Outputs: Permits multiple devices to share a common bus.
Additional Details
The MC74HCT541N features eight non-inverting buffers with 3-state outputs. It has two Output Enable (OE) inputs that control all eight outputs. When OE is low, the outputs are enabled, and the output signals follow the input signals. When OE is high, the outputs are in a high-impedance state. The device is available in a 20-pin DIP package. Operating temperature is -40°C to +85°C.
