The Texas Instruments SN74LS240N is a robust octal inverting buffer and line driver designed for enhancing signal integrity in digital systems. Housed in a through-hole 20‑pin PDIP package, it offers eight inverting channels with three‑state outputs ideal for bus-oriented applications and memory address buffering. With TTL-compatible inputs, fast propagation (approximately 18 ns at 5 V), and a broad voltage tolerance, it delivers reliable performance across various industrial and consumer electronics applications.

Why Buy the SN74LS240N?

If you're looking for an efficient, high‑density buffer solution, the SN74LS240N stands out with its combination of eight inverting channels, three‑state output control, and proven TTL‑level performance. Whether managing multiple signal lines on bus systems or driving clock and memory address lines, its industry-trusted LS (Low-Power Schottky) technology ensures reliable speed and noise resilience, making it a go-to component for engineers demanding stability and compatibility in legacy and mixed-voltage environments.

Product Highlights – What Makes It Stand Out

Octal Inverting Configuration: Delivers 8 synchronised inverting buffers per chip excellent for parallel signal control.
Three-State Output Control: Enables/disables outputs for seamless bus sharing and reduced interference.
Fast Propagation Delay (~18 ns at 5 V): Enables high-speed data flow with minimal latency essential for performance-sensitive applications.
Wide Supply Voltage Compatibility (4.75 V to 5.25 V): Ensures consistent behaviour in standard TTL 5 V environments.
High Output Drive Strength: Capable of sourcing or sinking substantial current (–15 mA high, 24 mA low) great for driving multiple loads.
Input Voltage Tolerance & Hysteresis: Accepts lower logic voltages (down to ~2 V), improving flexibility and noise margin.
