74LVC11PW,112 Equivalent & Substitute Parts

Part Overview

The 74LVC11PW,112 is a 3-channel AND gate logic IC manufactured by Nexperia USA Inc., housed in a 14-TSSOP surface mount package. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. The 74LVC series operates across a wide supply voltage range of 1.2V to 3.6V, making it suitable for low-voltage digital logic applications. Substitute parts must maintain functional equivalence in logic operation, package form factor, and electrical performance within specified tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74LVC11PW,112 is determined by the following critical parameters:

• Logic Function: Both main and substitute parts must implement a 3-channel, 3-input AND gate with identical truth table behavior
• Package Compatibility: Identical 14-TSSOP surface mount package ensures PCB layout compatibility without redesign
• Supply Voltage Range: Substitute must operate within the application's specified voltage window; the 74LCX11MTCX operates at 2V ~ 3.6V, which is compatible with 3.3V and higher voltage designs
• Output Drive Capability: Current output specifications (24mA, 24mA) must be maintained for proper signal integrity
• Propagation Delay: Maximum delay specifications ensure timing requirements are met in digital circuits
• Operating Temperature Range: The substitute's -40°C ~ 85°C range covers the primary industrial operating window, though the main part extends to 125°C

The 74LCX11MTCX from Fairchild Semiconductor qualifies as a direct substitute based on matching logic configuration, identical package form factor, and compatible electrical performance within the specified parameters.

Parameter Comparison

Engineering Selection Recommendations

The 74LCX11MTCX is suitable as a substitute for the obsolete 74LVC11PW,112 in applications operating at 2V supply voltage or higher. The substitute maintains identical logic function, package form factor, and output drive specifications. Both parts are RoHS compliant and carry equivalent regulatory classifications (ECCN: EAR99, HTSUS: 8542.39.0001).

The primary design consideration is the minimum supply voltage threshold: the 74LCX11MTCX requires a minimum of 2V, whereas the original 74LVC11PW,112 operates down to 1.2V. For applications requiring operation below 2V, the original part specification must be retained or alternative logic families evaluated.

The 74LCX11MTCX's active product status ensures ongoing availability and manufacturing support, addressing the obsolescence constraint of the original part.

Frequently Asked Questions (FAQ)

Q: Can the 74LCX11MTCX replace the 74LVC11PW,112 in all applications?

A: The 74LCX11MTCX is functionally equivalent for applications operating at 2V supply voltage or higher. Applications requiring operation below 2V require the original 74LVC11PW,112 or evaluation of alternative logic families.

Q: Are the packages physically identical?

A: Yes. Both parts use the 14-TSSOP (0.173", 4.40mm Width) surface mount package, enabling direct PCB layout compatibility without modification.

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

A: At 3.3V with 50pF load, the 74LVC11PW,112 specifies 6.2ns maximum delay, while the 74LCX11MTCX specifies 6ns maximum delay. Both meet typical digital logic timing requirements.

Q: Do both parts meet RoHS compliance?

A: The 74LVC11PW,112 is ROHS3 compliant. The 74LCX11MTCX meets equivalent RoHS standards. Both carry identical regulatory classifications.

Q: What is the operating temperature difference?

A: The 74LVC11PW,112 operates from -40°C to 125°C, while the 74LCX11MTCX operates from -40°C to 85°C. For applications requiring operation above 85°C, the original part specification must be retained.

Q: Are the input logic level thresholds compatible?

A: Both parts accept 3.3V logic signals. The 74LCX11MTCX has slightly narrower input threshold windows (0.7V ~ 0.8V for low, 1.7V ~ 2V for high) compared to the 74LVC11PW,112 (0.12V ~ 0.8V for low, 1.08V ~ 2V for high), but both are compatible with standard CMOS and TTL logic levels at 3.3V operation.
