74ALVC16374MTDX Equivalent & Substitute Parts

Part Overview

The 74ALVC16374MTDX is a dual 8-bit D-type flip-flop logic integrated circuit manufactured by onsemi, housed in a 48-TFSOP surface mount package. This component functions as a standard positive edge-triggered flip-flop with tri-state, non-inverted outputs, operating across a 1.65V to 3.6V supply voltage range. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74ALVC16374MTDX are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Functional Equivalence Criteria:

• Type: D-Type Flip-Flop with dual 8-bit configuration
• Output Type: Tri-State, Non-Inverted
• Trigger Type: Positive Edge
• Number of Elements: 2
• Number of Bits per Element: 8
• Voltage - Supply: 1.65V ~ 3.6V (matching range)
• Operating Temperature: -40°C ~ 85°C (TA)

Mechanical Compatibility Criteria:

• Package / Case: 48-TFSOP (0.240", 6.10mm Width)
• Mounting Type: Surface Mount

Performance Considerations:

• Clock Frequency: Substitute parts must support minimum 150 MHz operation
• Max Propagation Delay: Substitute parts must meet timing requirements within specified load conditions
• Current - Output High, Low: Must support required drive capability
• Current - Quiescent (Iq): Must not exceed 40 µA

The identified substitute parts maintain functional equivalence while meeting or exceeding the electrical and mechanical specifications of the original component.

Parameter Comparison

Engineering Selection Recommendations

Both Texas Instruments substitute parts (SN74ALVCH162374GR and SN74ALVCH16374DGGR) are active products with ROHS3 compliance, providing long-term availability and regulatory alignment compared to the obsolete 74ALVC16374MTDX.

SN74ALVCH162374GR is suitable for applications where output drive current of 12mA per line is sufficient. This part offers lower power consumption characteristics while maintaining the required functional and electrical specifications.

SN74ALVCH16374DGGR maintains the original 24mA output drive current specification, providing direct electrical compatibility with designs requiring higher output drive capability. This part is recommended for applications with demanding load conditions or where output current specifications are critical to system performance.

Both substitute parts operate within the same voltage supply range (1.65V ~ 3.6V) and temperature range (-40°C ~ 85°C) as the original component, with identical package and pinout configuration (48-TFSOP). The propagation delay specifications of both substitutes remain within acceptable engineering tolerances for standard logic applications.

Frequently Asked Questions (FAQ)

Q: Can the SN74ALVCH162374GR and SN74ALVCH16374DGGR be used interchangeably with the 74ALVC16374MTDX?

A: Both parts are functionally equivalent and pin-compatible with the 74ALVC16374MTDX. The primary difference is output drive current: SN74ALVCH162374GR provides 12mA per line, while SN74ALVCH16374DGGR provides 24mA per line (matching the original). Selection depends on your circuit's load requirements.

Q: What is the difference between the two Texas Instruments substitutes?

A: Both parts share identical functional specifications (dual 8-bit D-type flip-flops, positive edge trigger, tri-state outputs). The key differences are: SN74ALVCH162374GR has 12mA output drive current and 4.6ns propagation delay at 50pF load; SN74ALVCH16374DGGR has 24mA output drive current and 4.2ns propagation delay at 30pF load. Choose based on your output current and timing requirements.

Q: Are the substitute parts available in the same package?

A: Yes. All three parts use the 48-TFSOP (0.240", 6.10mm Width) surface mount package with identical pinout and mechanical dimensions, ensuring direct board-level compatibility.

Q: What is the impact of the lower clock frequency in the substitute parts?

A: The substitute parts operate at 150 MHz compared to the original 250 MHz. For standard logic applications operating below 150 MHz, this presents no functional limitation. Applications requiring operation above 150 MHz would require alternative component selection.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both Texas Instruments substitute parts (SN74ALVCH162374GR and SN74ALVCH16374DGGR) are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: What is the propagation delay difference between the parts?

A: The 74ALVC16374MTDX specifies 4.6ns at 3.3V with 50pF load. SN74ALVCH162374GR specifies 4.6ns at 3.3V with 50pF load, and SN74ALVCH16374DGGR specifies 4.2ns at 3.3V with 30pF load. These differences are within acceptable tolerances for standard logic timing applications.
