Product details
Overview
74LVC3G16 from Nexperia is a triple non-inverting buffer IC designed for voltage-level translation between 3.3 V and 5 V logic domains, featuring 1.65 V to 5.5 V supply operation, ±24 mA output drive at 3.0 V, IOFF partial power-down protection, and operation across –40 °C to +125 °C. It enables reliable signal buffering in mixed-voltage I/O interfaces on industrial control PCBs and FPGA peripheral expansion headers.
For engineers reviewing the 74LVC3G16 datasheet, 74LVC3G16 pinout, 74LVC3G16 application, or 74LVC3G16 equivalent, key selection criteria include 5 V-tolerant inputs/outputs, IOFF-enabled backflow prevention during power sequencing, propagation delay ≤4.0 ns (VCC = 4.5–5.5 V), and TSSOP8 (SOT505-2) package compatibility with high-density routing.
Technical Context
This device implements three independent CMOS buffer stages with identical input/output characteristics. Each channel supports bidirectional voltage translation without external biasing due to 5 V-tolerant inputs operating down to 1.65 V supply, and features an active-low IOFF circuit that disables outputs when VCC = 0 V to block damaging back-currents.
The logic function is strictly non-inverting (nY = nA), with static thresholds defined per JEDEC standards JESD8-7, JESD8-5, and JESD8B/JESD36. Propagation delay is characterized across five VCC ranges (1.65–5.5 V), with worst-case tpd of 10.8 ns at –40 °C to +85 °C and 1.65–1.95 V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - Enables direct integration into 1.8 V, 2.5 V, 3.3 V, and 5 V systems without level-shifter circuitry. |
| Input Voltage Tolerance | 0 V to 5.5 V - Allows safe connection to 5 V TTL or CMOS outputs even when powered from 1.65 V, eliminating clamping diodes. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - Sufficient to drive 50 Ω transmission lines or multiple 74LVC inputs under worst-case loading. |
| Propagation Delay | ≤4.0 ns (VCC = 4.5–5.5 V, Tamb = –40 to +125 °C) - Supports >200 MHz signal routing in timing-critical data paths. |
| IOFF Leakage Current | ±10 μA max at VCC = 0 V - Ensures <100 μW standby power in hot-swap or partial-power-down subsystems. |
| Operating Temperature | –40 °C to +125 °C - Qualified for under-hood automotive modules, industrial PLC I/O cards, and telecom line-card environments. |
| ESD Robustness | HBM >2000 V, CDM >1000 V - Reduces need for external ESD protection on board-level signal traces. |
Pinout & Package
TSSOP8 plastic thin shrink small outline package (SOT505-2); 8 leads; body width 3 mm; lead length 0.5 mm; pin 1 indicator located below marking code in lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6 (1A, 2A, 3A) | Data input | Three independent logic inputs accepting 0–5.5 V signals regardless of VCC level. |
| 2, 5, 7 (3Y, 2Y, 1Y) | Data output | Three non-inverting buffered outputs referenced to VCC; each drives ±24 mA at 3.0 V. |
| 4 | GND | Ground reference (0 V) for all internal circuitry and I/O thresholds. |
| 8 | VCC | Primary supply rail; powers all buffers and enables IOFF control when pulled to 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range | 1.65–5.5 V operation eliminates need for separate LDOs in multi-rail systems. |
| 5 V-tolerant I/O | Inputs and outputs withstand 5.5 V while VCC ≥1.65 V - enables plug-and-play interconnection with legacy 5 V peripherals. |
| IOFF partial power-down | Outputs go high-impedance when VCC = 0 V - prevents back-driving powered sections during hot insertion or power sequencing. |
| High noise immunity | Guaranteed VIH/VIL margins exceed 30% of VCC across full temperature and voltage range - reduces false triggering in noisy industrial environments. |
| JEDEC-compliant | Meets JESD8-7 (1.65–1.95 V), JESD8-5 (2.3–2.7 V), and JESD8B/JESD36 (2.7–3.6 V) - ensures interoperability with standard logic families. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC3G16DBVR | TI part in SOT-23-8 package; identical 1.65–5.5 V range and IOFF, but max output drive is ±24 mA only at VCC ≥ 4.5 V (vs. ≥3.0 V for Nexperia). | Limited drive capability at 3.3 V systems requiring >12 mA loads; requires derating for industrial temp range. | Select when footprint compatibility with TI-design legacy boards is mandatory and VCC ≥ 4.5 V is guaranteed. |
| 74AUP3G16GM | Nexperia AUP variant in XQFN8; lower ICC (0.9 μA typical), but narrower VCC range (0.8–3.6 V) and no 5 V tolerance - requires external clamping for 5 V inputs. | Not suitable for mixed 3.3/5 V translation; optimized for ultra-low-power battery-operated devices only. | Select only for sub-1 μA standby power targets where 5 V interfacing is absent and supply is strictly ≤3.6 V. |
Compared with SN74LVC3G16DBVR and 74AUP3G16GM, the 74LVC3G16 delivers consistent ±24 mA drive from 3.0 V onward and native 5 V tolerance - making it the sole option qualified for robust mixed-voltage translation across –40 °C to +125 °C without external components.

FAQ
Does the 74LVC3G16 support hot-swap insertion?
Yes - its IOFF circuit actively disables outputs when VCC = 0 V, preventing back-current flow into powered downstream circuits during live insertion. This feature is validated per JEDEC JESD78 and supports hot-swap compliance in modular I/O systems without additional isolation circuitry.
Can the 74LVC3G16 be used with 1.8 V microcontrollers driving 5 V peripherals?
Yes - its 5 V-tolerant inputs accept 0–5.5 V signals while operating from 1.8 V VCC, and its outputs swing rail-to-rail up to VCC. When VCC = 1.8 V, outputs drive ±4 mA (per datasheet Table 7), sufficient for light loads like enable lines or LED anodes, but not for heavy 5 V bus termination.
What is the maximum capacitive load the 74LVC3G16 can drive at 3.3 V while maintaining 4 ns propagation delay?
At VCC = 3.3 V and Tamb = 25 °C, the 74LVC3G16 maintains tpd ≤4.1 ns (typical) with 50 pF load and 500 Ω termination (per Table 10). With 30 pF load, tpd drops to ≤2.2 ns. Exceeding 50 pF increases delay nonlinearly and may induce ringing if trace impedance is mismatched.
Is the 74LVC3G16 qualified for automotive AEC-Q100 Grade 1?
No - this specific 74LVC3G16DP variant is rated for –40 °C to +125 °C but is not AEC-Q100 qualified. Nexperia offers automotive-qualified equivalents (e.g., 74LVC3G16DP-Q100) with full stress testing and PPAP documentation; those carry explicit "Q100" suffix and different ordering codes.
