Key Parameters

Substitute Part Grouping Explanation

Substitution for the 8534BMI-13LF is based on the following critical parameters:

• Functional Type: Fanout Buffer (Distribution), Multiplexer with 2:4 input-to-output ratio
• Frequency Capability: Maximum operating frequency of 266 MHz or higher
• Supply Voltage Compatibility: 3.135V ~ 3.465V operating range
• Input/Output Signal Compatibility: Support for LVCMOS and LVTTL input standards; LVCMOS output capability
• Operating Temperature Range: -40°C ~ 85°C
• Package Form Factor: Surface mount configuration

The substitute part 8534AGILF meets these criteria with enhanced frequency capability (350 MHz) and expanded input signal support, while maintaining the same supply voltage range, operating temperature specifications, and core 2:4 multiplexer functionality. The package change from 16-SOIC to 16-TSSOP represents a minor form factor variation within the same thermal and electrical performance class.

Parameter Comparison

Engineering Selection Recommendations

Both the 8534BMI-13LF and 8305AGILF are classified as Obsolete products from Renesas Electronics Corporation. Selection between these parts should be based on the following factors:

Supply Voltage and Temperature Compliance: Both parts operate within the identical 3.135V ~ 3.465V supply range and -40°C ~ 85°C temperature specification, ensuring electrical compatibility in existing designs.

Frequency Headroom: The 8305AGILF provides 350 MHz maximum frequency capability compared to 266 MHz for the 8534BMI-13LF. This additional frequency margin may provide design flexibility for future applications or margin in existing clock distribution networks.

Package Footprint: The 8534BMI-13LF uses a 16-SOIC package (0.154" width), while the 8305AGILF uses a 16-TSSOP package (0.173" width). PCB layout modifications are required for package substitution.

Regulatory Compliance: The 8305AGILF carries RoHS3 Compliant status. Both parts are REACH Unaffected and classified under ECCN EAR99.

Input/Output Signal Support: The 8305AGILF supports expanded input signal types (HCSL, LVCMOS, LVDS, LVHSTL, LVPECL, LVTTL, SSTL) and outputs LVCMOS and LVTTL. The 8534BMI-13LF accepts LVCMOS, LVTTL, and Crystal inputs with LVCMOS and LVPECL outputs. Verify signal compatibility with your specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can the 8305AGILF directly replace the 8534BMI-13LF without PCB modifications?

A: No. While both parts share identical electrical specifications (supply voltage, temperature range, 2:4 multiplexer ratio), the package form factors differ. The 8534BMI-13LF uses 16-SOIC packaging while the 8305AGILF uses 16-TSSOP packaging. PCB layout and footprint changes are required.

Q: What are the key electrical parameters that determine substitution compatibility?

A: The critical parameters are: 2:4 input-to-output ratio, 3.135V ~ 3.465V supply voltage range, -40°C ~ 85°C operating temperature, and surface mount configuration. Both parts meet these specifications.

Q: Does the higher frequency rating of the 8305AGILF (350 MHz vs. 266 MHz) affect compatibility?

A: No. Higher frequency capability is backward compatible. If your application operates at 266 MHz or below, the 8305AGILF will function correctly. The additional frequency margin does not introduce incompatibility.

Q: Are there input or output signal compatibility concerns between these parts?

A: The 8305AGILF supports a broader range of input signal types (HCSL, LVCMOS, LVDS, LVHSTL, LVPECL, LVTTL, SSTL) compared to the 8534BMI-13LF (LVCMOS, LVTTL, Crystal). Output signals differ: 8534BMI-13LF outputs LVCMOS and LVPECL, while 8305AGILF outputs LVCMOS and LVTTL. Verify that your specific input and output signal requirements are supported by the substitute part.

Q: What is the moisture sensitivity level for both parts?

A: Both the 8534BMI-13LF and 8305AGILF are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are both parts still available for procurement?

A: Both parts are classified as Obsolete. Availability through authorized distributors should be verified before design commitment.
