Product details
Overview
74LVC1G16GW-Q100 from Nexperia is an automotive-qualified single non-inverting buffer IC with 5 V-tolerant inputs, IOFF partial power-down protection, and Schmitt-trigger input hysteresis. It operates from 1.65 V to 5.5 V supply, delivers ±24 mA output drive at 3.0 V, and supports mixed-voltage interfacing in automotive body control modules and infotainment I/O expansion.
For engineers reviewing the 74LVC1G16GW-Q100 datasheet, 74LVC1G16GW-Q100 pinout, 74LVC1G16GW-Q100 application, or 74LVC1G16GW-Q100 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification, -40 °C to +125 °C operation, IOFF-enabled backflow prevention during power sequencing, and 5 V logic compatibility in 1.65 V–5.5 V systems.
Technical Context
This device implements a CMOS-based single-buffer function with rail-to-rail input voltage tolerance up to 5.5 V independent of VCC, enabling direct connection to legacy 5 V logic while powered from 1.8 V or 3.3 V rails. Its IOFF circuit actively disables outputs when VCC = 0 V, blocking destructive current flow during hot-swap or partial system shutdown.
The Schmitt-trigger input provides 0.3 V–0.5 V hysteresis (depending on VCC), ensuring robust noise immunity against slow-rising signals in automotive harness environments. Propagation delay ranges from 0.5 ns (VCC = 5.5 V) to 11.0 ns (VCC = 1.65 V, -40 °C to +125 °C), supporting both high-speed and ultra-low-power timing domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - Enables operation across 1.8 V, 2.5 V, 3.3 V, and 5 V domains without level shifters. |
| Input Voltage Tolerance | Up to 5.5 V - Allows direct interface with 5 V TTL/CMOS logic regardless of VCC setting. |
| IOFF Leakage Current | ±10 μA max at VCC = 0 V - Prevents damaging back-current during power-down sequencing in multi-rail systems. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - Sufficient to drive multiple LVC loads or moderate capacitive traces in ECUs. |
| Propagation Delay | 0.5 ns to 11.0 ns - Supports timing-critical signal buffering in CAN/LIN gateway interfaces and sensor preprocessing stages. |
| Operating Temperature | -40 °C to +125 °C - Qualified for under-hood and dashboard-mounted automotive electronics per AEC-Q100 Grade 1. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - Meets stringent automotive ESD immunity requirements for exposed I/O lines. |
Pinout & Package
TSSOP5 (SOT353-1) plastic thin shrink small outline package: 5-pin, 1.25 mm body width, 0.65 mm pitch, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (n.c.) | No-connect terminal | Internally unconnected; must remain floating - no PCB trace or solder mask required. |
| 2 (A) | Data input | Schmitt-triggered input accepting 0 V to 5.5 V; enables reliable edge detection on noisy automotive signals. |
| 3 (GND) | Ground reference | 0 V return path for all internal logic and output current; requires low-inductance connection to system ground plane. |
| 4 (Y) | Data output | Inverting buffer output with IOFF control; sinks/sourcing capability scales with VCC and load conditions. |
| 5 (VCC) | Power supply | Primary supply rail (1.65–5.5 V); powers internal logic and output stage; decoupling capacitor mandatory. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient, including thermal cycling and humidity testing. |
| IOFF partial power-down | Automatically disables Y output when VCC = 0 V, eliminating backfeed risk during firmware updates or module hot-swap. |
| 5 V tolerant inputs | Accepts 0–5.5 V input voltages regardless of VCC level - eliminates need for external level translators in mixed-voltage designs. |
| Schmitt-trigger input | Provides 0.3–0.5 V hysteresis to reject noise on long harness runs and suppress false triggering in body control units. |
| Low dynamic power | CPD = 15 pF at VCC = 3.3 V - minimizes switching power in always-on vehicle subsystems like door modules and lighting controllers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar single-buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G16DBVR | Industrial grade (-40 °C to +85 °C), no AEC-Q100 qualification, identical pinout and electrical specs. | Not qualified for under-hood or safety-critical zones; suitable only for cabin-concentrated modules. | Select when automotive qualification is unnecessary and cost optimization is prioritized over temperature range. |
| 74LVC1G17GW-Q100 | Same package and qualification, but includes Schmitt-trigger input only (no IOFF), slightly higher VIH/VIL thresholds. | Lacks IOFF protection - unsuitable for partial power-down scenarios like camera hot-swap or firmware update sequences. | Choose only when Schmitt-trigger noise immunity is primary requirement and full power sequencing control is not needed. |
Compared with SN74LVC1G16DBVR and 74LVC1G17GW-Q100, the 74LVC1G16GW-Q100 uniquely combines AEC-Q100 Grade 1 qualification, IOFF-enabled safe power sequencing, and 5 V input tolerance - making it the sole option for automotive applications requiring simultaneous mixed-voltage interfacing and controlled power-down behavior.

FAQ
Does the 74LVC1G16GW-Q100 support hot-swap insertion into a live 5 V bus?
No - while its inputs tolerate 5 V regardless of VCC, the device requires valid VCC before enabling output functionality. Inserting it into a live 5 V bus with VCC unpowered risks violating absolute maximum ratings due to uncontrolled current paths through internal ESD diodes. Always power VCC before applying input signals.
Can Pin 1 (n.c.) be used as a heatsink pad or grounded for thermal improvement?
No - Pin 1 is internally unconnected and electrically isolated. Connecting it to GND, VCC, or a thermal pad violates the SOT353-1 mechanical specification and may cause die stress or solder voiding. Thermal performance relies solely on copper pour under the exposed pad area (if present) and standard PCB layout practices for TSSOP5 packages.
What is the minimum load capacitance this buffer can drive while maintaining specified tpd?
The propagation delay values in the datasheet are measured with CL = 30 pF (VCC ≤ 2.0 V) or 50 pF (VCC ≥ 2.7 V). Driving loads below 15 pF may reduce tpd marginally but does not invalidate timing - however, sub-10 pF loads increase sensitivity to PCB trace inductance and require careful layout to avoid ringing or overshoot.
How does IOFF behave when VCC ramps from 0 V to nominal voltage?
IOFF remains active until VCC exceeds ~0.8 V, at which point the output transitions from high-impedance to functional state. During this transition, output leakage stays below ±10 μA, preventing unintended activation of downstream loads such as MOSFET gates or optocouplers in power management circuits.
