74VCX16841MTDX Equivalent & Substitute Parts

Part Overview

The 74VCX16841MTDX is a D-Type Transparent Latch IC manufactured by onsemi, featuring 2 independent 10:10 circuits with tri-state output capability. This component operates across a supply voltage range of 1.4V to 3.6V and is housed in a 56-TSSOP package. The part is currently classified as obsolete, making identification of compatible substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74VCX16841MTDX is determined by the following critical parameters:

• Logic Type: D-Type Transparent Latch
• Circuit Configuration: 2 Channel 10:10
• Output Type: Tri-State
• Propagation Delay: 1ns
• Operating Temperature Range: -40°C ~ 85°C
• Independent Circuits: 2

All identified substitute parts maintain identical logic functionality, circuit configuration, and propagation delay characteristics. Substitutes are grouped by output current capability and package type. Parts with 24mA output current provide direct electrical equivalence to the original component. Parts with 12mA output current are functionally compatible but with reduced drive capability. Package variations (56-TSSOP vs. 56-SSOP) affect PCB layout and assembly processes but do not alter electrical performance.

Parameter Comparison

Engineering Selection Recommendations

All Texas Instruments SN74ALVCH series substitutes are active production components with ROHS3 compliance and superior moisture sensitivity ratings (MSL 1 vs. MSL 2). Selection between substitute options depends on specific design constraints:

For direct electrical and package equivalence, SN74ALVCH16841DGGR and SN74ALVCH162841GR maintain the 56-TFSOP package footprint identical to the original 74VCX16841MTDX. SN74ALVCH16841DGGR and SN74ALVCH16841DLR provide matching 24mA output current specifications.

For designs tolerating package footprint changes, SN74ALVCH16841DL and SN74ALVCH16841DLR accommodate 56-BSSOP packaging while maintaining 24mA output current capability.

For applications where reduced output current is acceptable, SN74ALVCH162841DL and SN74ALVCH162841GR provide 12mA output current with active product status and improved compliance certifications.

All substitutes operate within the -40°C to 85°C temperature range and maintain 1ns propagation delay. Supply voltage compatibility requires verification: substitutes operate from 1.65V minimum versus the original 1.4V minimum specification.

Frequently Asked Questions (FAQ)

Q: Can SN74ALVCH162841 series parts directly replace the 74VCX16841MTDX?

A: SN74ALVCH162841 parts are functionally compatible but feature reduced output current (12mA vs. 24mA). Substitution is valid only if the application circuit does not require the higher drive capability of the original component.

Q: What is the difference between 56-TSSOP and 56-SSOP packages?

A: 56-TSSOP (Thin Shrink Small Outline Package) has a 0.240" width (6.10mm), while 56-SSOP (Shrink Small Outline Package) has a 0.295" width (7.50mm). These are distinct footprints requiring different PCB layouts and cannot be used interchangeably without board redesign.

Q: Are all substitute parts RoHS compliant?

A: All Texas Instruments SN74ALVCH substitutes are ROHS3 compliant. The original 74VCX16841MTDX RoHS status is not specified in available documentation.

Q: What is the significance of MSL rating differences?

A: The original component has MSL 2 (1 Year shelf life), while all substitutes have MSL 1 (Unlimited shelf life). Lower MSL ratings indicate superior moisture resistance and longer storage capability without baking requirements.

Q: Is the supply voltage range difference critical?

A: The original component operates from 1.4V minimum, while substitutes operate from 1.65V minimum. Applications requiring operation below 1.65V cannot use Texas Instruments substitutes without circuit modification.

Q: Which substitute provides the closest electrical match?

A: SN74ALVCH16841DGGR and SN74ALVCH16841DLR provide complete electrical equivalence with 24mA output current matching the original specification. SN74ALVCH16841DGGR maintains the identical 56-TFSOP package footprint.
