SN74HC163NG4 Equivalent & Substitute Parts

Part Overview

The SN74HC163NG4 is a 4-bit binary counter IC manufactured by Texas Instruments, designed for synchronous counting applications with positive edge triggering. This component features a 36 MHz count rate and operates across a 2V to 6V supply voltage range, making it suitable for digital logic circuits requiring reliable counting functionality.

The SN74HC163NG4 is currently discontinued at DiGi Electronics. Due to this discontinuation status, identifying equivalent substitute parts with identical electrical and mechanical specifications is essential for design continuity and procurement planning. Active alternatives maintain full functional compatibility while ensuring ongoing availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74HC163NG4 is determined by strict equivalence across the following critical parameters:

• Logic Function: Binary counter with 4-bit capacity
• Electrical Characteristics: 36 MHz count rate, 2V to 6V supply voltage, -40°C to 85°C operating range
• Trigger Mechanism: Positive edge triggering with synchronous reset
• Physical Form Factor: 16-DIP package with 0.300" (7.62mm) pitch
• Mounting Configuration: Through-hole technology

The SN74HC163N qualifies as a direct substitute based on identical electrical specifications, functional architecture, and package geometry. The primary distinction is product status: the SN74HC163N maintains active availability, whereas the SN74HC163NG4 is discontinued.

Parameter Comparison

Engineering Selection Recommendations

The SN74HC163N is the recommended substitute for the discontinued SN74HC163NG4. Both components are manufactured by Texas Instruments and maintain identical electrical performance specifications, functional architecture, and physical packaging. The SN74HC163N is currently in active production status with confirmed inventory availability.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications. The transition from the discontinued SN74HC163NG4 to the active SN74HC163N introduces no functional or electrical compromises and ensures long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Are the SN74HC163NG4 and SN74HC163N electrically identical?

A: Yes. Both components share identical electrical specifications including 36 MHz count rate, 2V to 6V supply voltage range, -40°C to 85°C operating temperature, and synchronous positive edge triggering architecture.

Q: Can the SN74HC163N be used as a direct replacement in existing designs?

A: Yes. The SN74HC163N is a direct functional and physical replacement. Both components use the 16-DIP through-hole package with identical pin configuration and electrical characteristics.

Q: What is the primary difference between these parts?

A: The SN74HC163NG4 is discontinued at DiGi Electronics, while the SN74HC163N maintains active production status. No electrical or functional differences exist between the two parts.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying equivalent regulatory requirements.

Q: Is the 16-DIP package suitable for both through-hole and surface-mount applications?

A: The 16-DIP package is designed for through-hole mounting only. Surface-mount alternatives would require a different package type not covered by this substitution analysis.
