Integrated Circuit IC 74LS EB323709307 4 channels, 2 inputs per channel, THT DIP-14

IC 74LS EB323709307 is a 74LS-series integrated circuit in a THT DIP-14 package offering four independent channels with two inputs per channel. Designed for through-hole mounting, this logic IC implements standard TTL-compatible functions useful in digital logic, signal routing and small control circuits. The compact DIP-14 form factor and established 74LS family characteristics make it suitable for prototyping, repairs and OEM assembly in applications that require reliable TTL logic gates.

Advantages

The THT DIP-14 package provides easy insertion into breadboards and through-hole PCBs, simplifying assembly and replacement. As a member of the 74LS series, the device offers TTL-compatible voltage and timing characteristics widely supported across digital designs. Having four channels with two inputs per channel enables multiple gate operations within a single package, saving board space and reducing component count.

Suitable for

• Prototyping on breadboards and development boards
• Repair and replacement of discontinued or legacy digital modules
• Small control circuits and signal routing in embedded projects
• Educational electronics and laboratory experiments with TTL logic

Key specifications

• Logic family: 74LS-series (low-power TTL)
• Package type: Through-hole DIP-14
• Channels: 4 independent channels
• Inputs per channel: 2 inputs
• Mounting style: THT (through-hole technology)
• Typical applications: digital logic gates, signal routing, small control circuits

How to use

Place the DIP-14 package into a compatible socket or solder it into a through-hole PCB following correct orientation so that pin 1 aligns with the board marking. Provide a stable 5 V power supply consistent with TTL requirements and connect signal inputs to the appropriate input pins while observing input voltage levels and timing constraints. Use standard decoupling practices such as a 0.1 µF ceramic capacitor close to the supply pins to stabilize the power rail. Verify connections and logic levels with a multimeter or logic probe before applying system power.

Usage recommendations

For reliable operation, operate within manufacturer-recommended supply and temperature ranges, avoid exposing the device to static discharge during handling, and place bypass capacitors near the power pins. When replacing components on legacy boards, compare pinouts and logic functions to ensure compatibility with existing circuitry.
