SN74HC05APWRG4 Equivalent & Substitute Parts

Part Overview

The SN74HC05APWRG4 is a 6-channel inverter logic integrated circuit manufactured by Texas Instruments, featuring open-drain outputs in a 14-TSSOP surface-mount package. This device is classified as obsolete, which necessitates identification of active equivalent alternatives for continued design support and procurement.

The SN74HC05APWRG4 operates across a 2V to 6V supply voltage range and is suitable for applications requiring logic inversion with open-drain output capability. The obsolete status of this component requires engineers to identify functionally equivalent active alternatives to maintain supply chain continuity and ensure long-term design viability.

Parameter Comparison

Engineering Selection Recommendations

The MC74HC05ADTG from onsemi is a direct functional and electrical equivalent to the obsolete SN74HC05APWRG4. Selection of the onsemi alternative is supported by the following factors:

Compliance and Certification: Both devices maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols.

Product Status: The MC74HC05ADTG maintains active product status with onsemi, providing assured long-term availability and supply chain continuity compared to the obsolete Texas Instruments part.

Electrical Performance: The onsemi device meets or exceeds all specified electrical parameters. The quiescent current specification of 1 µA on the MC74HC05ADTG is lower than the 2 µA maximum of the SN74HC05APWRG4, representing improved power efficiency. The operating temperature range of -55°C to 125°C on the onsemi part exceeds the -40°C to 85°C range of the Texas Instruments device, providing broader environmental operating capability.

Package and Pinout: Both devices utilize identical 14-TSSOP surface-mount packaging with matching physical dimensions (0.173", 4.40mm Width), enabling direct board-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the MC74HC05ADTG directly replace the SN74HC05APWRG4 in existing designs?

A: Yes. The MC74HC05ADTG is electrically and functionally equivalent across all specified parameters. Both devices feature 6-channel inverter logic with open-drain outputs, identical supply voltage ranges (2V ~ 6V), matching input/output logic levels, and identical propagation delay specifications. The 14-TSSOP package pinout is identical, enabling direct board-level substitution.

Q: What are the differences between these two parts?

A: The primary differences are manufacturer and product status. The SN74HC05APWRG4 is obsolete from Texas Instruments, while the MC74HC05ADTG is an active product from onsemi. The MC74HC05ADTG features a lower maximum quiescent current (1 µA versus 2 µA) and a wider operating temperature range (-55°C to 125°C versus -40°C to 85°C). These differences represent improvements in power efficiency and environmental operating capability.

Q: Are there any packaging differences between the SN74HC05APWRG4 and MC74HC05ADTG?

A: No. Both devices are supplied in 14-TSSOP surface-mount packages with identical physical dimensions of 0.173" width and 4.40mm width specification. No PCB layout modifications are required for substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the SN74HC05APWRG4 and MC74HC05ADTG are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity ratings. The MC74HC05ADTG additionally carries REACH Unaffected status.

Q: What is the significance of the obsolete status of the SN74HC05APWRG4?

A: Obsolete status indicates that Texas Instruments has discontinued manufacturing and support for this device. The MC74HC05ADTG from onsemi is an active product with assured availability, making it the appropriate selection for new designs and long-term supply chain planning.

Q: Are the electrical specifications identical between these parts?

A: The core electrical specifications are equivalent. Both devices operate at 2V ~ 6V supply voltage, feature identical input logic levels (Low: 0.5V ~ 1.8V; High: 1.5V ~ 4.2V), output current (5.2mA), and propagation delay (15ns @ 6V, 50pF). The MC74HC05ADTG features a lower maximum quiescent current specification, which is a performance advantage.
