Product details
Overview
74LVC27D,112 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 interface, and signal conditioning circuits.
For engineers reviewing the 74LVC27D,112 datasheet, 74LVC27D,112 pinout, 74LVC27D,112 application, or 74LVC27D,112 equivalent, this page delivers verified package mapping (SO14/SOT108-1), confirmed static/dynamic electrical parameters, JEDEC-compliant voltage thresholds, ESD robustness data (HBM >2000 V), and two validated alternative parts for functional substitution in industrial and embedded designs.
Technical Context
The 74LVC27D,112 implements three independent 3-input NOR gates using advanced CMOS technology, supporting mixed-voltage system interfacing via 5.5 V-tolerant inputs while powered from 1.2–3.6 V. Its logic behavior follows standard Boolean NOR truth table with active-low outputs.
It complies with multiple JEDEC standards (JESD8-7A, JESD8-5A, JESD8-C/JESD36) across distinct VCC ranges and is characterized over −40 °C to +125 °C, enabling use in extended-temperature industrial environments without derating penalties beyond specified thermal limits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.2 V to 3.6 V - Enables direct integration into low-voltage microcontroller I/O domains and battery-powered systems. |
| Input Voltage Tolerance | Up to 5.5 V - Allows safe interfacing with legacy 5 V TTL or LVTTL signals without external level shifters. |
| Propagation Delay (tpd) | 0.8 ns (min) at VCC = 3.0–3.6 V - Supports high-speed timing-critical logic functions such as address decoding and state machine control. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - Sufficient to drive multiple LVC/LVT inputs or small capacitive loads without buffering. |
| Operating Temperature | −40 °C to +125 °C - Qualified for under-hood automotive auxiliary modules and industrial motor controllers. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Reduces risk of field failure during handling and board assembly in automated production lines. |
| Power Dissipation Cap | 500 mW at Tamb ≤ 85 °C (SO14) - Defines maximum continuous power envelope before thermal derating begins. |
Pinout & Package
74LVC27D,112 uses the SO14 plastic small outline package (SOT108-1), 14-pin, 3.9 mm body width, with gull-wing leads and standard JEDEC pin 1 index marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 9 | 1A / 2A / 3A | First input of each NOR gate - Accepts 5.5 V-tolerant logic signals regardless of VCC level. |
| 2, 4, 10 | 1B / 2B / 3B | Second input of each NOR gate - Electrically identical to A inputs; supports wired-OR expansion when used with open-drain drivers. |
| 13, 5, 11 | 1C / 2C / 3C | Third input of each NOR gate - Completes full 3-input Boolean evaluation per gate; no internal pull-up/down. |
| 12, 6, 8 | 1Y / 2Y / 3Y | Active-low NOR output - Sinks or sources up to ±24 mA; VOH/VOL specified down to 1.2 V VCC. |
| 7 | GND | Digital ground reference - Must be connected to system 0 V plane; decoupling capacitor recommended within 5 mm. |
| 14 | VCC | Positive supply rail - Requires local 100 nF ceramic decoupling; not internally regulated or clamped. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (1.2–3.6 V) | Enables single-supply operation across ultra-low-power sensor nodes (1.2 V) and 3.3 V FPGA I/O banks without voltage translation. |
| 5.5 V-tolerant inputs | Eliminates need for external level-shifting circuitry when interfacing with 5 V microcontrollers or legacy peripherals. |
| JEDEC-compliant voltage thresholds | Guarantees interoperability with JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C (2.7–3.6 V) logic families. |
| High-temperature operation (−40 to +125 °C) | Supports deployment in engine control units, industrial PLC backplanes, and outdoor telecom infrastructure without derating. |
| Low dynamic power (CPD = 9.2 pF @ 3.0–3.6 V) | Reduces switching-related power consumption in high-frequency clock distribution or address bus gating applications. |

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 pinout and DC specs, but tpd max = 7.6 ns @ 125 °C vs. 6.8 ns for 74LVC27D,112. | Same industrial temperature grade; slightly higher propagation delay margin at extreme temperature. | Select SN74LVC27DR if dual-sourcing from TI is required and 0.8 ns tighter delay is not critical. |
| 74AUP27GW,125 | NXP AUP family; lower VCC range (0.8–3.6 V), lower ICC (0.9 µA typ), but reduced drive (±4 mA) and slower tpd (11.5 ns @ 3.0 V). | Better suited for ultra-low-power always-on monitoring, not high-drive or high-speed applications. | Choose 74AUP27GW,125 only for battery-operated edge sensors where power budget dominates speed requirements. |
Compared with SN74LVC27DR and 74AUP27GW,125, the 74LVC27D,112 offers the best balance of speed (sub-1 ns min tpd), drive strength (±24 mA), and wide VCC flexibility (1.2–3.6 V), making it optimal for mixed-signal industrial control where both performance and compatibility matter.

FAQ
What is the absolute maximum supply voltage for the 74LVC27D,112?
The absolute maximum supply voltage (VCC) for the 74LVC27D,112 is +6.5 V, as defined in Table 4 of the NXP datasheet. However, continuous operation above 3.6 V violates recommended operating conditions and may cause permanent damage or parametric shift. Functional operation is guaranteed only between 1.2 V and 3.6 V.
Does the 74LVC27D,112 support 5 V logic inputs while powered at 1.8 V?
Yes - the 74LVC27D,112 features 5.5 V-tolerant inputs, meaning it accepts VI up to 5.5 V regardless of VCC level (1.2–3.6 V). This allows direct connection to 5 V TTL outputs without level shifters, even when the device itself is powered from 1.8 V, as confirmed in Table 5 and Section 2.
What is the output drive capability of the 74LVC27D,112 at 2.7 V supply?
At VCC = 2.7 V, the 74LVC27D,112 guarantees VOH ≥ 2.2 V and VOL ≤ 0.4 V when sourcing or sinking 12 mA, respectively (Table 6). This corresponds to a minimum output drive strength of ±12 mA under those conditions, sufficient to drive 10 LVC loads or moderate PCB trace capacitance.
Is the 74LVC27D,112 qualified for automotive applications?
No - the 74LVC27D,112 is rated for −40 °C to +125 °C operation but is not AEC-Q100 qualified. NXP explicitly states in Section 15.3 that non-automotive qualified products like the 74LVC27D,112 are not tested to automotive reliability standards and carry no warranty for use in safety-critical vehicle systems.
What package type does the 74LVC27D,112 use and what is its lead count?
The 74LVC27D,112 uses the SO14 plastic small outline package (SOT108-1), a 14-lead surface-mount package with 3.9 mm body width and gull-wing leads. Pin 1 is marked by a notch or dot, and the package conforms to JEDEC MS-012 standards, as detailed in Figure 8 and Table 1.
