Product details

Overview

74LVC27D,118 from NXP Semiconductors is a triple 3-input NOR gate logic IC operating across 1.2 V to 3.6 V supply, delivering propagation delays as low as 0.8 ns at 3.0–3.6 V, with ±24 mA output drive capability and input tolerance up to 5.5 V. It serves as a level-translating combinational logic element in digital control, bus interfacing, and signal conditioning circuits.

For engineers reviewing the 74LVC27D,118 datasheet, 74LVC27D,118 pinout, 74LVC27D,118 application, or 74LVC27D,118 equivalent, key selection considerations include its wide V_CC range (1.2–3.6 V), 5.5 V-tolerant inputs, −40 °C to +125 °C industrial temperature rating, SO14 package compatibility, and JEDEC-compliant voltage standards (JESD8-7A/5A/C).

Technical Context

The 74LVC27D,118 implements three independent 3-input NOR gates using advanced CMOS technology, enabling direct TTL-level interfacing and mixed-voltage system integration. Its input structure supports overvoltage tolerance without external clamping, while output stages deliver rail-to-rail swing and symmetrical drive strength.

Designed for robust operation in extended temperature environments, the device complies with multiple JEDEC interface standards (JESD8-7A, JESD8-5A, JESD8-C/JESD36) and meets stringent ESD requirements: >2000 V HBM, >200 V MM, and >1000 V CDM per JESD22-A114F/A115-B/C101E.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Function	Three independent 3-input NOR gates - enables compact implementation of OR-NOT logic in control decoding and enable/disable routing
Supply Voltage Range	1.2 V to 3.6 V - supports single-supply operation across 1.8 V, 2.5 V, 3.3 V, and legacy 1.2 V logic domains
Input Voltage Tolerance	Up to 5.5 V - allows safe interfacing with higher-voltage peripherals without level shifters
Propagation Delay (t_pd)	0.8 ns (min) at V_CC = 3.0–3.6 V - ensures timing-critical combinational logic paths meet sub-nanosecond budgets
Output Drive Strength	±24 mA at V_CC = 3.0 V - sufficient to drive 50 Ω transmission lines or fan-out to ≥10 LVC loads
Operating Temperature	−40 °C to +125 °C - qualified for under-hood automotive modules, industrial PLCs, and high-reliability embedded controllers
ESD Protection	HBM >2000 V, MM >200 V, CDM >1000 V - exceeds IEC 61000-4-2 system-level immunity requirements for board-level handling

Pinout & Package

74LVC27D,118 is housed in an SO14 (SOT108-1) plastic small outline package: 14-lead, 3.9 mm body width, 1.27 mm pitch, with gull-wing leads and standard JEDEC MO-122 footprint.

Pin/Terminal	Circuit Role	Design Meaning
1, 3, 9	1A / 2A / 3A	First input of each NOR gate - accepts 0–5.5 V logic signals regardless of V_CC
2, 4, 10	1B / 2B / 3B	Second input of each NOR gate - electrically identical to A inputs; no internal differentiation
13, 5, 11	1C / 2C / 3C	Third input of each NOR gate - completes 3-input Boolean NOR function per gate
12, 6, 8	1Y / 2Y / 3Y	Active-low NOR output - sinks or sources up to 24 mA with rail-aligned VOH/VOL
7	GND	Digital ground reference - must be connected to system 0 V plane; decoupling capacitor required near pin
14	V_CC	Positive supply rail - powers all three gates; requires local 100 nF ceramic bypass capacitor

Key Features

Feature	Design Value
Wide V_CC range (1.2–3.6 V)	Enables drop-in use in 1.2 V, 1.8 V, 2.5 V, and 3.3 V systems without redesign or voltage translation

JEDEC-standard compliance	Validated for JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C/JESD36 (2.7–3.6 V) - ensures interoperability across voltage-tiered logic families
High ESD robustness	HBM >2000 V, MM >200 V, CDM >1000 V - reduces field failure risk during assembly and end-use handling
Extended temperature grade	Specified from −40 °C to +125 °C - supports deployment in engine control units, motor drives, and outdoor industrial equipment

Equivalent & Alternatives

The following parts are listed as comparable options for similar 3-input NOR gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC27DR	TI-manufactured SO14 variant; identical logic function, pinout, and DC specs; t_pd max 6.8 ns at 3.3 V vs. 5.9 ns for 74LVC27D,118	Same industrial temperature range (−40 °C to +125 °C); slightly relaxed timing margin at 3.3 V	Select when TI-sourced supply chain alignment is required; verify timing slack in critical paths
74AHC27D,118	NXP AHC-family variant; higher V_CC range (2–5.5 V); faster t_pd (2.5 ns typ at 5 V) but no 5.5 V input tolerance below 4.5 V V_CC	Optimized for 5 V systems; lacks 1.2–3.6 V flexibility and 5.5 V input tolerance at low V_CC	Choose only for pure 5 V designs requiring higher speed; not suitable for mixed-voltage or low-V_CC operation

Compared with SN74LVC27DR and 74AHC27D,118, the 74LVC27D,118 uniquely balances ultra-wide supply range (1.2–3.6 V), guaranteed 5.5 V input tolerance across all V_CC, and best-in-class propagation delay at 3.3 V - making it optimal for portable, battery-powered, and multi-rail embedded systems.

FAQ

What is the maximum supply voltage for the 74LVC27D,118?

The absolute maximum supply voltage (V_CC) for the 74LVC27D,118 is +6.5 V, but the recommended operating range is strictly 1.2 V to 3.6 V. Operation above 3.6 V voids guaranteed performance and may cause permanent damage. The 74LVC27D,118 is not rated for continuous 5 V operation - use 74AHC27D,118 instead for 5 V systems.

Does the 74LVC27D,118 support 5 V input signals?

Yes, the 74LVC27D,118 accepts input voltages up to 5.5 V regardless of V_CC level - a key feature enabling direct interfacing with 5 V microcontrollers, sensors, or legacy peripherals without external level shifters. This capability is explicitly specified in Table 4 (Limiting Values) and Table 5 (Recommended Operating Conditions) of the NXP datasheet.

What package type is used for the 74LVC27D,118?

The 74LVC27D,118 uses the SO14 (SOT108-1) plastic small outline package: 14-lead, 3.9 mm body width, 1.27 mm lead pitch, and JEDEC MO-122 compliant footprint. Pin 1 is marked by a notch or dot; thermal pad is absent - unlike the DHVQFN14 variant (74LVC27BQ).

Is the 74LVC27D,118 suitable for automotive applications?

No - the 74LVC27D,118 is not automotive-qualified. While it operates from −40 °C to +125 °C, it lacks AEC-Q100 qualification, automotive-grade screening, and specific automotive reliability testing. For automotive use, select NXP's automotive-qualified equivalents such as the 74LVC27ADPWJ or consult NXP's official automotive portfolio documentation before design-in.

How many independent logic gates does the 74LVC27D,118 contain?

The 74LVC27D,118 contains exactly three independent 3-input NOR gates. Each gate has three dedicated inputs (e.g., 1A/1B/1C) and one dedicated output (1Y), with no shared internal nodes or configurable logic - confirmed by the functional diagram (Figure 3), pin description table (Table 2), and truth table (Table 3) in the NXP datasheet.
