74LS04 Hex Inverter IC Chip 30pcs Pack Todiys SN74LS04N

Description

Product Overview

The 74LS04 hex inverter integrated circuit is a fundamental building block for digital designers who need reliable logic level inversion across multiple channels. Manufactured by Todiys, this device adheres to the classic TTL (Transistor-Transistor Logic) family specifications, ensuring compatibility with a broad ecosystem of legacy and modern components. Packaged in a 14‑pin DIP (Dual In‑Line Package) format, the chip measures 0.6 inches wide, 0.3 inches tall, and 0.2 inches deep, making it easy to mount on standard breadboards, prototype boards, or through‑hole PCBs. Each of the six independent inverters provides a high‑speed transition with a typical propagation delay of 10 ns, while consuming less than 0.5 mA per gate when idle, which translates to low overall power draw for multi‑gate applications. The device operates over a supply voltage range of 4.75 V to 5.25 V, delivering a guaranteed logic high output of at least 2.4 V and a logic low output of no more than 0.4 V, meeting the stringent noise margins required in industrial control, communication interfaces, and embedded system designs. The 30‑piece lot includes individually sealed units, each bearing the SN74LS04N marking, ensuring traceability and authenticity for engineers who demand consistent performance across large production runs.

Usage

Designed for versatility, the 74LS04 inverter finds application in a wide variety of environments. In educational labs, it serves as a hands‑on example of Boolean NOT operations, allowing students to experiment with signal inversion, timing analysis, and cascade logic design. In industrial settings, the chip is frequently employed within signal conditioning circuits, where it converts high‑level logic signals to their complementary states for driving relays, optocouplers, or other downstream devices. Hobbyists and makers appreciate the DIP‑14 footprint for its ease of insertion into hobbyist prototyping boards, enabling rapid iteration of microcontroller interfacing projects, such as level shifting between 5 V and 3.3 V domains. The robust TTL output characteristics also make the 74LS04 suitable for driving LED arrays, where the inverted output can directly control current‑limiting resistors without additional transistor stages. Because the device tolerates a wide temperature range from –55 °C to +125 °C, it is well‑suited for outdoor instrumentation, automotive control modules, and aerospace subsystems where environmental extremes are a concern. The 30‑piece package ensures that engineers have sufficient spares for iterative testing, batch production, and field service replacements, reducing downtime and inventory costs.

FAQ

What is the difference between the 74LS04 and other inverter families?

The 74LS04 belongs to the Low‑Power Schottky (LS) family, offering faster switching speeds and lower power draw compared to standard 74xx logic families, while maintaining compatible voltage levels.

Can the 74LS04 be used with a 3.3 V supply?

While the device is specified for a 5 V supply, it can operate at 3.3 V in some applications, but the logic level thresholds may not meet TTL specifications, so careful testing is recommended.

Is the DIP‑14 package suitable for surface‑mount technology?

The DIP‑14 package is intended for through‑hole mounting. For surface‑mount designs, a compatible SMD version such as the SO‑14 package should be selected.

How many units are included in the 30‑piece pack?

The package contains thirty individually sealed 74LS04 ICs, each tested for compliance with the SN74LS04N specifications.

What warranty or return policy applies to this product?

All units are covered by a 12‑month limited warranty against manufacturing defects, and returns are accepted within 30 days of receipt provided the items are in original condition.
