SN74ALS05ADRE4

Overview

The SN74ALS05ADRE4 is a hex inverter integrated circuit manufactured by Texas Instruments, belonging to the Advanced Low-Power Schottky (ALS) logic family. It features six independent inverters with open-collector outputs housed in a 14-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a wide operating temperature range from -55°C to +125°C. Key electrical characteristics include a propagation delay of 13 ns and a low-level output current capability of 8 mA.

Feature Summary

• Advanced Low-Power Schottky technology ensures high-speed operation while maintaining reduced power consumption compared to standard LS logic families.
• Open-collector outputs allow for flexible interfacing, including wired-OR configurations and direct driving of indicators or loads requiring higher voltage or current levels than standard CMOS outputs.

Applications

• General-purpose digital signal inversion in industrial control systems
• Driving external loads such as LEDs or relays via open-collector configuration
• Level shifting between different logic voltage domains

Procurement Notes

Verify the suffix 'E4' indicates lead-free composition and RoHS compliance per Texas Instruments specifications. Confirm the package type matches the required PCB footprint, specifically the plastic small-outline (D) package. Ensure the ordering quantity aligns with the manufacturer's reel packaging requirements for the ADRE4 variant.

Selection Notes

Select this component when designing circuits that require high-speed switching with open-collector outputs in harsh thermal environments. It serves as a suitable replacement for older SN54S05 or SN74S05 devices where improved power efficiency and extended temperature ranges are necessary. Verify input compatibility with TTL or LSTTL logic sources.

Part Context

This part belongs to the SN54/74ALS05 series of hex inverters with open-collector outputs. It is an enhanced version of the standard SN54S05/SN74S05, offering faster switching speeds and lower power dissipation. The 'E4' suffix denotes environmental compliance, specifically lead-free manufacturing processes adhering to international standards.

Replacement Considerations

Direct pin-compatible replacements include SN54S05J, SN74S05D, SN54LS05J, and SN74LS05D. When substituting, verify that the alternative device meets the required operating temperature range and output drive capabilities for the specific application load.
