NXP Semiconductors 74HCT03DB,112

Overview

74HCT03DB,112 from Nexperia USA Inc. is a quad 2-input NAND gate with open-drain outputs in SSOP package. Its compatibility depends on logic family, threshold behavior, output structure, timing, and control pins rather than package code alone.

74HCT03DB,112 is most relevant to logic-level translation, control-signal buffering, timing and counter logic, embedded interface glue logic, where the surrounding circuit depends on the same rating profile, footprint, thermal behavior, and sourcing continuity.

Technical Context

74HCT03DB,112 is a logic-family IC whose real compatibility depends on supply range, input thresholds, output structure, timing, and pinout. Package suffixes can change assembly without changing the logic name.

For glue logic and interface paths, 74HCT03DB,112 must be matched to the surrounding voltage domain. Enable pins, open-drain outputs, Schmitt inputs, counters, or latches can change system behavior if substituted loosely.

Key Specifications

Pinout & Package

74HCT03DB,112 uses SSOP package. Pin mapping, polarity, or item format should be matched to the exact board, fixture, or procurement requirement before replacement.

Key Features

• 74HCT03DB,112 is identified as a quad 2-input NAND gate with open-drain outputs.
• 5 V logic-family supply class voltage or operating class for the relevant circuit stress.
• logic output-drive current class current or output class, subject to package and thermal derating.
• SSOP package package or item format for procurement and assembly review.
• standard Nexperia logic ordering
• controlled input thresholds

Applications

Equivalent & Alternatives

When evaluating 74HCT03DB,112 equivalent devices, compare voltage rating or operating class, current or output capability, package and footprint, pin mapping or polarity, thermal behavior, qualification suffix, lifecycle and sourcing status. A similar family name is not enough when the board depends on timing, leakage, firmware, optical output, or protection behavior.

Quality

74HCT03DB,112 should be sourced as original Nexperia USA Inc. material through traceable and controlled supply channels. Quality verification may include logic input/output testing, supply-current screening, package coplanarity inspection, marking review, and reel label verification, along with incoming inspection suited to quad 2-input NAND gate with open-drain outputs production, repair, or lifecycle procurement.

Availability

74HCT03DB,112 is available at Aetrix Electronics and suitable for logic-level translation, control-signal buffering, timing and counter logic, embedded interface glue logic requiring 5 V logic-family supply class, SSOP package in a controlled BOM or repair program.

Supply support may include scheduled delivery planning, volume procurement support, BOM continuity assistance, traceable sourcing management, and lifecycle availability coordination for manufacturers, repair teams, contract manufacturers, and engineering buyers managing quad 2-input NAND gate with open-drain outputs demand.

For production deployment, confirming package fit, pin mapping or polarity, electrical rating, temperature margin, lifecycle status, approved manufacturer identity, and sourcing continuity helps reduce qualification risk for 74HCT03DB,112.

FAQ

What is 74HCT03DB,112 used for?

74HCT03DB,112 is used for logic-level translation, control-signal buffering, timing and counter logic. In those circuits, 74HCT03DB,112 provides the quad 2-input NAND gate with open-drain outputs function with 5 V logic-family supply class, SSOP package. The final selection should match the schematic role, operating stress, package footprint, and sourcing requirements.

What logic family details matter for 74HCT03DB,112?

74HCT03DB,112 must match the intended logic family, supply range, input thresholds, output structure, timing, and package pinout. For 74HCT03DB,112, a different 74-series suffix can change package, automotive grade, or control behavior even when the broad function looks similar.

What should be checked in the 74HCT03DB,112 pinout?

The 74HCT03DB,112 pinout should be checked for VCC, GND, input pins, output pins, enables, direction controls, triggers, or latch controls depending on the function. Incorrect pin mapping on 74HCT03DB,112 can cause bus contention, stuck outputs, or timing faults.

Can 74HCT03DB,112 be replaced by a similar part?

74HCT03DB,112 can be compared with similar family members only after electrical limits, package, orientation, qualification suffix, timing or leakage behavior, and approved-source rules are reviewed. A similar name alone is not enough because 74HCT03DB,112 may carry package, program, bin, or lifecycle details.

Why source 74HCT03DB,112 through Aetrix Electronics?

Sourcing 74HCT03DB,112 through Aetrix Electronics supports traceable procurement, scheduled delivery planning, BOM continuity assistance, and lifecycle availability coordination. This is useful when 74HCT03DB,112 is needed for production builds, repair lots, controlled alternates, or long-running equipment support.
