The 74LS367APC is a dual non-inverting buffer from the 74LS logic family, designed for 5V TTL systems. It features two channels with 3-State outputs, capable of sinking 24mA and sourcing 2.6mA. Operating from 4.75V to 5.25V, this buffer is ideal for bus interfacing, signal distribution, and driving loads in legacy and industrial applications. The 16-DIP package is breadboard-friendly.
- 3-State Outputs: Enables bus multiplexing and safe disconnection.
- High Sink Current (24mA): Drives LEDs, relays, and other loads directly.
- DIP Package: Easy to prototype and service in through-hole designs.
- 74LS Compatibility: Works with standard TTL logic levels.
Legacy 5V Bus Buffering
Use the 74LS367APC to buffer address or data lines in older 5V microprocessor systems. The 3-State outputs allow multiple peripherals to share the bus.
TTL Logic Interfacing
Interface between TTL logic gates and higher-current loads. The 24mA sink capability drives relays, LEDs, or small motors.
Memory Expansion
Buffer control signals for memory expansion boards. The DIP package is ideal for through-hole prototyping and breadboarding.
Industrial Control Panels
Drive indicator lamps or small solenoids in industrial control panels. The 3-State feature allows safe disconnection during maintenance.
Educational Labs
Use in university labs to teach bus architecture and 3-State logic. The DIP package is easy to handle and replace.
Signal Distribution
Distribute a single clock or reset signal to multiple loads. The buffer ensures consistent signal levels across all outputs.
