DM74LS367AN Equivalent & Substitute Parts

Part Overview

The DM74LS367AN is a non-inverting buffer IC manufactured by onsemi, designed for logic signal buffering applications. This 16-pin DIP package device features 2 elements with 2 and 4 (Hex) bits per element, operating at 4.75V to 5.25V supply voltage across a 0°C to 70°C temperature range. The product is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and legacy design support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DM74LS367AN is determined by strict alignment of the following critical parameters:

• Logic Function: Buffer, Non-Inverting configuration
• Element Count: 2 elements
• Bit Configuration: 2, 4 (Hex) bits per element
• Supply Voltage Range: 4.75V ~ 5.25V
• Output Current Specifications: 2.6mA (high), 24mA (low)
• Operating Temperature Range: 0°C ~ 70°C
• Package Type: 16-DIP (0.300", 7.62mm)
• Mounting Configuration: Through Hole

The SN74LS367AN meets all substitution criteria. Both devices share identical electrical specifications, pin configuration, and physical packaging. The primary distinction is the output type classification (3-State for SN74LS367AN versus standard output for DM74LS367AN), which does not affect functional compatibility in applications requiring non-inverting buffer operation within the specified parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the DM74LS367AN and SN74LS367AN are classified as obsolete products with RoHS non-compliant status. Selection between these parts should be based on availability and inventory status. The SN74LS367AN currently maintains higher inventory levels (3650 Pcs) compared to the DM74LS367AN (1327 Pcs), making it the preferred choice for procurement in legacy system support scenarios. Both devices carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications, ensuring equivalent regulatory treatment.

Frequently Asked Questions (FAQ)

Q: Can the SN74LS367AN directly replace the DM74LS367AN in existing designs?

A: Yes. Both devices share identical electrical specifications, pin assignments, and 16-DIP package dimensions. Direct substitution is supported without circuit modification.

Q: What is the significance of the 3-State output designation for the SN74LS367AN?

A: The 3-State output capability indicates the device can assume a high-impedance state in addition to logic high and low states. This feature does not prevent operation in applications designed for standard output devices.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both devices carry identical RoHS non-compliant status, ECCN classification (EAR99), and HTSUS codes (8542.39.0001).

Q: What mounting considerations apply to these 16-DIP devices?

A: Both parts use through-hole mounting with 0.300" (7.62mm) DIP spacing. Standard DIP sockets and PCB footprints designed for 16-pin DIP packages are compatible with both devices.

Q: Why is the DM74LS367AN classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. Equivalent alternatives such as the SN74LS367AN remain available from existing inventory stocks.
