ICS854104AG Equivalent & Substitute Parts

Part Overview

The ICS854104AG is a Clock Fanout Buffer (Distribution) IC manufactured by Renesas Electronics Corporation, designed for 1:4 clock distribution at frequencies up to 700 MHz. This device features differential input and output capabilities with support for multiple input standards including HCSL, LVDS, LVHSTL, LVPECL, and SSTL, outputting LVDS signals. The part is packaged in a 16-TSSOP surface mount package.

The ICS854104AG has reached obsolete product status. Identifying qualified substitute components is necessary to maintain design continuity and ensure supply chain reliability for new production runs and ongoing support of existing systems.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ICS854104AG is determined by the following critical parameters:

• Functional Configuration: 1:4 clock distribution ratio with differential input and output
• Frequency Capability: Maximum operating frequency of 700 MHz
• Input/Output Standards: Support for LVDS output and compatibility with HCSL, LVDS, LVPECL, and SSTL input standards
• Package Compatibility: 16-TSSOP surface mount package with identical physical dimensions (0.173", 4.40mm Width)
• Supply Voltage Range: Operating voltage compatibility within specified ranges
• Operating Temperature Range: Functional performance across specified temperature conditions

The substitute parts identified (NB3L8504SDTG and NB3L8504SDTR2G) from onsemi meet all critical functional and physical requirements. Both parts maintain the 1:4 fanout buffer configuration, 700 MHz maximum frequency, LVDS output, and 16-TSSOP package specification. The primary differences are packaging format (Tube vs. Tape & Reel) and product status (Active vs. Obsolete).

Parameter Comparison

Engineering Selection Recommendations

Both NB3L8504SDTG and NB3L8504SDTR2G are active, production-supported alternatives to the obsolete ICS854104AG. The onsemi parts provide expanded operating temperature range (-40°C to 85°C versus 0°C to 70°C) and wider supply voltage tolerance (2.375V to 3.63V versus 3.135V to 3.465V), offering enhanced flexibility for diverse application environments.

The substitute parts carry ROHS3 compliance certification, addressing regulatory requirements that may not have applied to the original Renesas component. Both maintain identical functional specifications for clock distribution: 1:4 fanout ratio, 700 MHz maximum frequency, differential LVDS output, and 16-TSSOP package geometry.

Selection between NB3L8504SDTG and NB3L8504SDTR2G depends on procurement and assembly requirements. The Tube packaging (NB3L8504SDTG) suits lower-volume or prototype applications, while Tape & Reel packaging (NB3L8504SDTR2G) is optimized for high-volume automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Are the NB3L8504 parts pin-compatible with the ICS854104AG?

A: Yes. Both substitute parts use the 16-TSSOP package with identical physical dimensions (0.173", 4.40mm Width) and surface mount configuration. Pin assignments for clock distribution function are compatible.

Q: What is the functional difference between the ICS854104AG and NB3L8504 series?

A: Both devices perform 1:4 clock fanout buffering at 700 MHz with differential LVDS output. The NB3L8504 series adds translator functionality and supports HSTL input in addition to HCSL, LVDS, LVPECL, and SSTL standards supported by the ICS854104AG.

Q: Can I use NB3L8504SDTG and NB3L8504SDTR2G interchangeably?

A: The electrical and functional specifications are identical. The difference is packaging format: Tube versus Tape & Reel. Selection depends on assembly process requirements and volume. Both are active production parts from onsemi.

Q: Does the wider operating temperature range of the NB3L8504 affect circuit design?

A: No. The NB3L8504 series (-40°C to 85°C) encompasses the original ICS854104AG temperature range (0°C to 70°C). Designs validated for the original part remain valid with the substitute.

Q: What is the impact of the wider supply voltage range on my design?

A: The NB3L8504 series accepts 2.375V to 3.63V, which includes the original 3.135V to 3.465V range. Existing power supply designs require no modification. The expanded range provides additional design margin.

Q: Are there any compliance differences I should consider?

A: The NB3L8504 parts are ROHS3 compliant, while the ICS854104AG is RoHS non-compliant. If your application or market requires RoHS compliance, the onsemi substitutes satisfy this requirement.

Q: Which substitute should I select for new production designs?

A: For new designs, either NB3L8504SDTG or NB3L8504SDTR2G is appropriate. Choose based on your manufacturing process: Tube packaging for lower volumes or manual assembly, Tape & Reel for automated high-volume production.
