What are the key features of SN74LS07NE4?
- 6-channel non-inverting open-collector outputs support up to 30V and 40mA sink current per channel
- LS TTL family with low-power Schottky transistors reduces propagation delay while keeping quiescent current low
- Open-collector architecture allows wired-AND bus connections and direct drive of relays, LEDs, and solenoids
- 14-pin PDIP package compatible with breadboard prototyping and standard IC socket assembly
- Wide output voltage compliance to 30V enables direct interfacing between 5V TTL logic and 12V or 24V loads
What is SN74LS07NE4 used for?
The SN74LS07NE4 is used as a line driver and level translator in industrial control systems, PLCs, and embedded boards where 5V TTL logic signals must switch 12V or 24V relay coils, indicator LEDs, or solenoid valves without additional discrete transistors. Its 6 independent open-collector channels allow wired-AND logic configurations on shared bus lines, simplifying multi-master communication circuits. Legacy board repair, educational lab kits, and prototype designs also rely on its 14-pin PDIP form factor for easy socket-based installation.

Frequently Asked Questions
What is the maximum output sink current and output voltage for each channel of the SN74LS07NE4?
Each of the 6 channels of the SN74LS07NE4 can sink up to 40mA of current and withstand up to 30V when the output transistor is off, allowing direct connection to 12V relay coils, 24V solenoids, and high-brightness indicator LEDs without external transistor buffers. This combination of 40mA sink current and 30V voltage compliance makes it one of the most versatile TTL open-collector drivers in the LS family.
How does the open-collector output topology of the SN74LS07NE4 enable wired-AND bus connections?
The open-collector outputs of the SN74LS07NE4 can be tied together with a single pull-up resistor to create a wired-AND function: the shared bus is pulled high only when all connected outputs are in their high-impedance (off) state. Any output pulling the bus low dominates, implementing the AND function in hardware without additional gate ICs. This technique is widely used in I2C-like shared signal lines and interrupt buses where multiple 5V TTL devices must share a common wire.
When would a designer choose the SN74LS07NE4 over the SN74LS06 for an industrial interface circuit?
A designer chooses the SN74LS07NE4 (non-inverting) over the SN74LS06 (inverting) when the logic polarity of the input signal must be preserved at the output without an inversion stage. For example, in a PLC output module driving 24V indicator lamps, the non-inverting buffer ensures that a logic-HIGH input turns the lamp ON, matching the expected software control model. Both devices have identical 40mA / 30V open-collector ratings, so the choice is purely about signal polarity.
What interface standards can the SN74LS07NE4 drive given its 30V, 40mA open-collector specification?
With 30V off-state voltage and 40mA sink current per channel, the SN74LS07NE4 can drive RS-232 lines in conjunction with a pull-up to +12V, control 12V relay coils, interface with 24V industrial sensor outputs, and directly drive LED arrays requiring up to 40mA each. Its LS TTL input thresholds (VIH ≥ 2V, VIL ≤ 0.8V) ensure compatibility with standard 5V TTL and CMOS logic families across 6 independent channels.
