The SN74S240N3 is a high-speed inverting buffer from Texas Instruments' 74S Schottky family. It provides two channels with 3-State outputs, enabling efficient bus interfacing and signal inversion. Operating from a 4.75V to 5.25V supply, it delivers 15mA source and 64mA sink current, ensuring robust drive capability. Housed in a 20-pin DIP package, it is ideal for 5V digital systems, memory address buffering, and industrial control logic.
- High-Speed Schottky Logic: The 74S family delivers fast propagation delays, critical for high-frequency 5V systems.
- High Sink Current (64mA): Drives heavy loads like LED arrays or multiple logic inputs without additional buffers.
- 3-State Outputs: Enables safe bus sharing with high-impedance control, simplifying multi-device architectures.
- Wide Temperature Range (0°C to 70°C): Suitable for commercial and industrial environments.
5V Digital Bus Interfacing
Use the SN74S240N3 to buffer and invert address or data lines in 5V microprocessor systems. Its 3-State outputs allow multiple devices to share the bus without contention, controlled by output enable signals.
Signal Inversion in Control Logic
Invert control signals such as reset or enable lines with the inverting buffer function. The high sink current (64mA) ensures strong signal integrity even with long PCB traces or multiple loads.
Driving Indicator LEDs
With 64mA sink capability, the buffer can directly drive LED arrays or status indicators. The 3-State feature lets you disable outputs during low-power modes, saving energy.
Memory Address Decoding
Buffer and invert address lines between a CPU and memory modules. The 74S family's high-speed Schottky technology minimizes propagation delay, critical for fast memory access cycles.
Industrial Logic Systems
In industrial controllers operating at 5V, this buffer provides reliable signal conditioning. The 0°C to 70°C temperature range suits most factory floor environments.
Test Equipment Interfaces
Use it in benchtop test gear to buffer and invert trigger signals. The DIP package is breadboard-friendly, enabling rapid prototyping of custom instrumentation.
