Key Parameters

Substitute Part Grouping Explanation

Substitution for the 74HC283N,652 is determined by the following critical parameters:

• Logic Function: Binary full adder with fast carry (4-bit)
• Package Type: 16-DIP through-hole configuration with 0.300" (7.62mm) pitch
• Number of Bits: 4-bit operation
• Mounting Technology: Through-hole compatibility
• Supply Voltage Compatibility: Operating voltage range must overlap or encompass the original specification
• Operating Temperature Range: Must support the required thermal envelope

The substitute parts listed below maintain functional equivalence through identical logic architecture and package form factor. Voltage supply ranges and temperature specifications are provided to enable selection based on specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

CD74HC283E: This Harris Corporation substitute maintains identical voltage supply specifications (2V ~ 6V) and package configuration as the 74HC283N,652. The extended operating temperature range (-55°C ~ 125°C) provides additional thermal margin. However, this part is RoHS non-compliant, which may impact suitability for applications subject to environmental regulations. Selection is appropriate for legacy systems where RoHS compliance is not mandated.

CD74ACT283E: This Harris Corporation part operates within a narrower supply voltage window (4.5V ~ 5.5V) compared to the original specification. This restriction limits applicability to systems with fixed 5V supply rails. The extended temperature range (-55°C ~ 125°C) and identical package form factor support direct mechanical substitution. RoHS non-compliance status applies to this part as well. Selection is appropriate only when supply voltage constraints are satisfied.

Frequently Asked Questions (FAQ)

Q: Can the CD74HC283E directly replace the 74HC283N,652?

A: Yes. Both parts share identical logic function, 4-bit architecture, 16-DIP package configuration, and overlapping supply voltage specifications (2V ~ 6V). Direct pin-for-pin substitution is supported. RoHS compliance status differs; verify regulatory requirements for your application.

Q: What is the key difference between CD74HC283E and CD74ACT283E?

A: The primary difference is supply voltage range. CD74HC283E operates from 2V to 6V, matching the original part. CD74ACT283E is restricted to 4.5V to 5.5V operation. Both maintain identical logic function and 16-DIP package form factor. Select based on your system's supply voltage specification.

Q: Are these substitutes pin-compatible with the 74HC283N,652?

A: Yes. All listed substitutes use the 16-DIP (0.300", 7.62mm) package with identical pinout. Through-hole mounting compatibility is maintained across all parts.

Q: Does RoHS compliance affect functional performance?

A: No. RoHS status indicates manufacturing process compliance with environmental regulations but does not alter electrical performance or functional characteristics. Selection should be based on system regulatory requirements and application constraints.

Q: Can I use CD74ACT283E in a system designed for 2V to 6V operation?

A: No. CD74ACT283E is specified for 4.5V to 5.5V operation only. Use only in systems with fixed 5V supply rails. For systems requiring 2V to 6V operation, select CD74HC283E or the original 74HC283N,652.
