Product details
Overview
74LVC1G27GN,132 from Nexperia is a single 3-input NOR gate logic IC in XSON6 (SOT1115) package, operating from 1.65 V to 5.5 V supply, featuring Schmitt-trigger inputs for noise immunity and IOFF partial power-down protection. It supports mixed-voltage interfacing between 3.3 V and 5 V systems and delivers ±24 mA output drive at VCC = 3.0 V. Used in level translation and signal conditioning within compact digital control circuits.
For engineers reviewing the 74LVC1G27GN,132 datasheet, 74LVC1G27GN,132 pinout, 74LVC1G27GN,132 application, or 74LVC1G27GN,132 equivalent, key selection criteria include input voltage tolerance up to 5 V, guaranteed operation from –40 °C to +125 °C, propagation delay as low as 1.0 ns at 5.5 V, IOFF-enabled backflow prevention during power-down, and compatibility with TTL-level inputs.
Technical Context
This device implements a single 3-input NOR Boolean function (Y = NOT(A OR B OR C)) with fully buffered CMOS outputs and Schmitt-trigger inputs that tolerate slow-rising/falling edges. The IOFF circuit actively disables outputs when VCC = 0 V, blocking destructive current flow in partial-power-down systems.
It complies with JEDEC standards JESD8-7, JESD8-5, JESD8C, and JESD36 across its full 1.65 V–5.5 V supply range and meets HBM ESD >2000 V and CDM ESD >1000 V per JS-001/JS-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 3-input NOR gate (Y = ¬(A ∨ B ∨ C)) - provides basic combinational logic for enable/disable, reset, or arbitration circuits. |
| Supply Voltage Range | 1.65 V to 5.5 V - enables direct interface with both 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without level shifters. |
| IOFF Support | Yes - prevents backflow current during partial power-down, critical for hot-swap and multi-rail system integrity. |
| Propagation Delay | 1.0 ns (min) to 4.5 ns (max) at VCC = 5.5 V - ensures timing-critical signal routing in high-speed control paths. |
| Output Drive | ±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 industrial and extended-temperature embedded applications. |
| Input Voltage Tolerance | Up to 5.5 V independent of VCC - allows safe connection to higher-voltage signals in mixed-supply domains. |
Pinout & Package
XSON6 package (SOT1115): extremely thin small outline, no leads, 6-terminal surface-mount package with body dimensions 0.9 × 1.0 × 0.35 mm. Pin 1 indicator located on lower-left corner below marking code "Y7".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Data input | First 3-input NOR operand; Schmitt-triggered for noise margin and edge-rate tolerance. |
| 2 (GND) | Ground reference | 0 V return path for all internal circuitry and output current sinking. |
| 3 (B) | Data input | Second 3-input NOR operand; electrically identical to Pin 1 with same input thresholds. |
| 4 (Y) | Data output | Inverted OR result; CMOS push-pull output capable of ±24 mA drive at 3.0 V. |
| 5 (VCC) | Supply voltage | Primary power rail (1.65–5.5 V); powers internal logic and enables IOFF control when at 0 V. |
| 6 (C) | Data input | Third 3-input NOR operand; shares identical AC/DC characteristics with Pins 1 and 3. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range | 1.65 V to 5.5 V operation - eliminates need for external voltage translators in heterogeneous logic systems. |
| Schmitt-trigger inputs | Hysteresis ≥0.3 V at VCC = 3.3 V - rejects noise on slow or noisy control lines (e.g., front-panel switches, sensor outputs). |
| IOFF partial power-down | Output high-impedance state when VCC = 0 V - prevents bus contention and backfeed in powered-down subsystems. |
| TTL input compatibility | VIH ≤ 2.0 V and VIL ≥ 0.8 V across full VCC range - ensures reliable recognition of standard TTL output levels. |
| ESD robustness | HBM >2000 V, CDM >1000 V - reduces field failure risk in manual handling and board assembly environments. |
Applications
| Industrial PLC I/O Expansion | USB-C Power Delivery Control |

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 |
|---|---|---|---|
| SN74LVC1G27DBVR | Same logic function and IOFF, but in SOT-23-6 (SOT23-6) package (2.9 × 1.6 × 1.45 mm); 2× larger footprint, higher thermal resistance. | Preferred where hand-soldering or legacy board layouts require leaded package; unsuitable for ultra-dense designs. | Select when mechanical compatibility with existing SOT-23 footprints is required and space constraints are relaxed. |
| 74AUP1G27GW,125 | Lower static current (0.9 μA vs. 4 μA), wider temp range (–40 °C to +125 °C), but no IOFF support and reduced drive (±4 mA at 3.0 V). | Better for always-on ultra-low-power nodes; not suitable for partial-power-down systems or driving heavier loads. | Choose only for battery-powered endpoints where power budget <1 μA dominates over robustness and drive capability. |
Compared with SN74LVC1G27DBVR, the 74LVC1G27GN,132 saves >65% board area and improves thermal performance in dense layouts; versus 74AUP1G27GW,125, it trades 3.1× higher quiescent current for essential IOFF protection and 6× stronger output drive-critical for industrial reliability.

FAQ
Can 74LVC1G27GN,132 operate reliably at 1.65 V supply while driving a 15 pF load?
Yes. At VCC = 1.65 V, the device guarantees tPD ≤ 25.7 ns into a 30 pF load per datasheet Table 8, and static output drive meets VIH/VIL thresholds down to 1.65 V. With a lighter 15 pF load, propagation delay improves further, and VOL remains ≤0.35 × VCC (≤0.58 V) ensuring noise margin.
Does the IOFF feature activate automatically when VCC drops below a threshold?
Yes. IOFF engages when VCC falls to 0 V (or near 0 V), forcing outputs into high-impedance state regardless of input voltages. This behavior is intrinsic to the circuit design and requires no external control signal or biasing-verified across –40 °C to +125 °C per datasheet Section 1.
Is the Schmitt-trigger hysteresis specified separately for each input pin?
No. All three inputs (A, B, C) share identical Schmitt-trigger characteristics. Datasheet Table 7 defines VIH and VIL with hysteresis implied by the gap between them-for example, at VCC = 3.3 V, VIH(min) = 2.0 V and VIL(max) = 0.8 V, yielding ≥1.2 V hysteresis window.
What is the maximum allowable input voltage when VCC = 0 V?
Per Table 5, VI may reach –0.5 V to +6.5 V regardless of VCC state. When VCC = 0 V, inputs remain tolerant up to +6.5 V, enabling safe "live insertion" into powered-backplane systems without damage-confirmed by absolute maximum ratings and IOFF-enabled isolation.
