The CD74LPT541AQM is a single inverting buffer from Harris Corporation, part of the 74LPT logic family. It operates from 2.7V to 3.6V, providing a 3-State output for bus-oriented applications. With 24mA source and sink capability, it can drive moderate loads. The 20-pin SSOP package (0.154" width) is compact for space-limited designs. Typical uses include signal inversion, bus isolation, and level shifting.
- Low-Voltage Operation (2.7V-3.6V): Compatible with modern 3.3V logic and low-power systems.
- 3-State Output: Enables bus sharing and power savings in idle mode.
- Compact SSOP Package: Saves board space in dense designs.
- Inverting Function: Provides signal polarity inversion without extra components.
Single-Line Signal Inversion
Use the CD74LPT541AQM to invert a single control signal, such as an enable or reset line, in a 3.3V system.
Bus Isolation for Low-Power Devices
The 3-State output allows the buffer to disconnect from the bus, reducing power consumption in battery-operated devices.
Level Shifting from 2.7V to 3.3V
With a 2.7V minimum supply, it can interface with lower-voltage sensors while driving 3.3V logic.
Driving Optocouplers in Industrial Controls
The 24mA output current can drive optocoupler LEDs, providing galvanic isolation in industrial control circuits.
Clock Signal Buffering
Buffer and invert a clock signal to drive multiple loads, ensuring consistent timing across the system.
Prototype and Breadboard Projects
Its simple single-channel design makes it ideal for educational projects and rapid prototyping.
