74LS04 Hex Inverter 5‑Pack DIP‑14 Open Collector Logic Gate by Todiys

Description

Product Overview

The 74LS04 hex inverter series from Todiys is a versatile collection of six independent NOT gates packaged in a standard DIP‑14 form factor. Each gate features an open‑collector output, allowing designers to easily interface with a wide range of voltage levels and to implement wired‑OR configurations without additional components. Constructed with high‑quality silicon and robust lead frames, these inverters deliver consistent switching performance across a temperature range of -55°C to 125°C, making them ideal for harsh industrial environments as well as hobbyist prototyping. The package dimensions of 3.43 x 2.28 x 0.24 inches and a lightweight of just 0.25 ounces ensure minimal board space usage while maintaining excellent thermal dissipation. With a typical propagation delay of 13 ns and a fan‑out capability of up to 10 standard TTL loads, the 74LS04 provides both speed and reliability for modern digital designs.

Usage

These hex inverters are suited for a broad spectrum of applications, ranging from simple signal conditioning in microcontroller circuits to complex logic implementations in programmable logic controllers (PLCs). The open‑collector outputs enable easy level shifting, allowing the device to drive higher voltage loads such as relay coils, LED arrays, or even small motors when paired with appropriate pull‑up resistors. Engineers often employ the 74LS04 in bus‑oriented architectures where multiple devices share a common line, taking advantage of the wired‑OR capability to simplify circuit design and reduce component count. In educational settings, the inverters serve as an excellent teaching tool for illustrating fundamental Boolean operations and the effects of propagation delay on timing analysis. Hobbyists appreciate the ease of integration into breadboard prototypes and the ability to cascade multiple inverters for signal inversion or buffering without sacrificing performance.

FAQ

What is the difference between a standard TTL inverter and the 74LS04 open‑collector version?

The standard TTL inverter provides a push‑pull output that actively drives both high and low states, while the 74LS04 open‑collector version only sinks current, requiring an external pull‑up resistor. This design offers greater flexibility for level shifting and allows multiple outputs to be tied together safely.

Can the 74LS04 be used to drive higher voltage loads such as 12 V relays?

Yes, by connecting an appropriate pull‑up resistor to the desired voltage level, the open‑collector output can switch higher voltage loads. Ensure the resistor value is chosen to limit current within the device’s specifications.

Is the 74LS04 suitable for low‑power battery‑operated projects?

Absolutely. The low power consumption of the LS family, combined with the ability to disable unused gates, makes the 74LS04 an efficient choice for battery‑powered designs where power budget is critical.

How many inverters are included in the 5‑piece pack?

The pack contains five separate DIP‑14 packages, each housing six independent NOT gates, providing a total of thirty inverter channels for extensive logic implementation.

What warranty or after‑sales service does Todiys provide?

Todiys offers a one‑year limited warranty covering manufacturing defects, along with responsive after‑sales support to address any technical questions or concerns you may encounter during product integration.
