SN74LS04D

Inverter Gates Overview

The SN74LS04D is a hex inverter integrated circuit belonging to the Texas Instruments SN74LS series of low-power Schottky logic devices. It contains six independent inverting gates within a single package. The device operates with a supply voltage range of 4.75 V to 5.25 V and features a maximum propagation delay of 15 ns at 5 V. It provides an output current drive capability of 8 mA for low-level outputs and -0.4 mA for high-level outputs. The component is housed in a 14-pin SOIC surface-mount package and supports an operating temperature range from 0 °C to 70 °C.

Inverter Gates Feature Summary

• Contains six independent inverting gates for signal inversion
• Utilizes low-power Schottky (LS) technology for reduced power consumption
• Provides standard TTL-compatible logic levels

Inverter Gates Applications

• Digital logic circuits requiring signal inversion
• Clock signal generation and conditioning
• Frequency divider circuits

Inverter Gates Procurement Notes

Verify that the specific part number matches the required package type, as the SN74LS04 designation exists in multiple form factors including DIP and SOIC. Confirm the manufacturer source, as the 'SN' prefix typically indicates Texas Instruments origin, while onsemi may offer equivalent parts under different numbering schemes. Ensure the voltage and temperature specifications align with the target application environment before procurement.

Inverter Gates Selection Notes

Select this component when a hex inverter function is required within low-power Schottky logic designs. It serves as a direct functional replacement for other 74LS04 variants provided the package footprint and pinout compatibility are maintained. Consider the 15 ns propagation delay and 8 mA drive strength against load requirements to ensure signal integrity in the intended digital system.

Inverter Gates Part Context

The SN74LS04D is part of the broader 74LS family, which combines the speed of the original 74S series with significantly lower power dissipation. This specific variant integrates six inverters, making it suitable for applications needing multiple logic inversions without consuming excessive board space or power compared to older transistor-transistor logic families.

Inverter Gates Replacement Considerations

Equivalent components include the SN74LS04N (PDIP package) and generic 74LS04 devices from other manufacturers such as National Semiconductor or STMicroelectronics, provided they adhere to the same LS logic electrical standards.
