Product details
Overview
74HCT2G16GWH from Nexperia is a dual non-inverting buffer gate in TSSOP6 (SOT363-2) package, operating at 4.5 V to 5.5 V supply, delivering 10 ns typical propagation delay (VCC = 4.5 V, CL = 50 pF), ±4 mA output drive, and TTL-compatible input thresholds. It serves as a level-shifting and signal-isolation buffer in digital control logic paths of industrial I/O modules and sensor interface subsystems.
For engineers reviewing the 74HCT2G16GWH datasheet, 74HCT2G16GWH pinout, 74HCT2G16GWH application, or 74HCT2G16GWH equivalent, key selection criteria include its 5 V TTL-compatible inputs, guaranteed operation up to +125 °C, low 9 pF power dissipation capacitance, and dual-channel independent buffering without internal feedback or enable control.
Technical Context
This device implements two independent CMOS buffer stages with TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), enabling direct interfacing with legacy 5 V TTL logic while maintaining CMOS power efficiency. Each channel provides non-inverting logic translation with no internal latching or timing control.
It operates across -40 °C to +125 °C ambient temperature, supports unlimited input rise/fall times, and features ESD protection exceeding 2000 V HBM and 1000 V CDM - critical for robustness in industrial PCB environments with transient coupling risks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures compatibility with standard 5 V TTL systems and avoids overvoltage stress on inputs. |
| Propagation Delay | 10 ns typical (VCC = 4.5 V, CL = 50 pF) - enables reliable timing in sub-25 MHz synchronous digital interfaces. |
| Output Drive | ±4.0 mA (VOH/VOL at VCC = 4.5 V) - sufficient to drive one 74-series TTL input or two 74HC inputs without fanout limitation. |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - guarantees unambiguous logic recognition when driven by 5 V TTL outputs. |
| Power Dissipation Cap. | 9 pF - determines dynamic power consumption (PD = CPD × VCC² × fi); enables low-power operation at high frequencies. |
| Operating Temp. | -40 °C to +125 °C - qualified for under-hood automotive control modules and industrial motor drives. |
| ESD Rating | HBM > 2000 V, CDM > 1000 V - meets IEC 61000-4-2 Level 2 immunity requirements for board-level handling and field operation. |
Pinout & Package
TSSOP6 (SOT363-2) package: plastic thin shrink small outline, 6-pin, 1.25 mm body width, 0.65 mm lead pitch, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First buffer input - accepts TTL/CMOS logic levels; no internal pull-up/down. |
| 2 | GND | Digital ground reference - must be connected directly to system ground plane for noise immunity. |
| 3 | 2A | Second buffer input - electrically isolated from 1A; supports independent signal routing. |
| 4 | 2Y | Second buffer output - non-inverted replica of 2A; capable of sourcing/sinking ±4 mA. |
| 5 | VCC | Positive supply - decoupling capacitor (100 nF) required within 5 mm for stable switching performance. |
| 6 | 1Y | First buffer output - non-inverted replica of 1A; matches 2Y in drive strength and timing. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | VIH ≥ 2.0 V and VIL ≤ 0.8 V at 4.5–5.5 V - eliminates need for external level shifters when interfacing with legacy 5 V logic. |
| Wide temperature range | Operates from -40 °C to +125 °C - supports deployment in engine control units and industrial PLC backplanes without derating. |
| Balanced propagation delays | tpd matching ≤ 1 ns between channels - preserves signal skew in parallel data paths such as address bus conditioning. |
| Low dynamic power | CPD = 9 pF - reduces switching current demand in battery-powered remote I/O nodes running at 10 MHz. |
| High noise immunity | Input hysteresis not present, but VIH/VIL margins exceed 0.7 V - suppresses false triggering from <1.5 V rail noise. |
Applications
| Industrial Sensor Interface | PLC Digital I/O Module |
|---|---|
Use Scenario: Isolating analog-to-digital converter (ADC) status flags from noisy 24 V DC field wiring. IC Role / Device Role / Timing Role: Dual buffer isolates ADC BUSY and RDY signals, preventing ground loop coupling into precision analog sections. Use Value: Eliminates need for optocouplers or discrete transistors - reduces BOM count and layout area while maintaining 10 ns timing integrity. |

IC Role / Device Role / Timing Role: Buffers expand drive capability beyond MCU's 4 mA limit, ensuring clean edges across 5 cm PCB traces. Use Value: Enables fanout of 1:2+ without signal degradation - sustains setup/hold timing margins at 20 MHz clock rates. |
| Automotive Body Control Unit | Medical Diagnostic Equipment |
Use Scenario: Level-shifting door lock actuator enable signals from 3.3 V MCU to 5 V solenoid drivers. IC Role / Device Role / Timing Role: Provides TTL-compatible input recognition and 5 V CMOS output swing for downstream power FET gates.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual buffer gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT2G16GV | SC-74 (SOT457) package, identical electrical specs - same pinout but 3.1 mm body length vs. 2.2 mm for TSSOP6. | Higher thermal resistance (4.1 mW/K derating above 89 °C) - less suitable for high-density, convection-cooled layouts. | Select GV for legacy SC-74 footprint compatibility; prefer GW for space-constrained designs requiring lower profile. |
| SN74LVC2G16DBVR | Lower VCC range (1.65–5.5 V), higher speed (6.5 ns typ), but LVTTL input thresholds - not TTL-compatible at 5 V. | Requires external resistor network to meet VIH ≥ 2.0 V at 5 V, increasing component count and board area. | Choose only if system uses mixed 3.3 V/5 V rails and full TTL compatibility is not required. |
Compared with 74HCT2G16GV and SN74LVC2G16DBVR, the 74HCT2G16GWH uniquely combines true 5 V TTL input compatibility, TSSOP6 space efficiency, and guaranteed +125 °C operation - making it optimal for automotive and industrial control where interoperability and thermal resilience are non-negotiable.

FAQ
Is 74HCT2G16GWH pin-compatible with 74HC2G16GW?
Yes - both share identical SOT363-2 (TSSOP6) pinout and function table. However, 74HCT2G16GWH has TTL-compatible inputs (VIH ≥ 2.0 V), while 74HC2G16GW requires CMOS-level inputs (VIH ≥ 70% VCC). Substitution is safe only when driving sources meet HCT's input threshold requirements.
What is the maximum capacitive load this device can drive reliably?
At VCC = 4.5 V and Tamb = 25 °C, 74HCT2G16GWH maintains specified VOL ≤ 0.26 V and VOH ≥ 4.18 V up to 50 pF load capacitance. For loads exceeding 50 pF, propagation delay increases linearly (e.g., ~29 ns at 150 pF), and output transition time degrades - use local termination or reduce trace length.
Does this device require external pull-up or pull-down resistors on unused inputs?
No - unused inputs must be tied HIGH or LOW via direct connection to VCC or GND. Floating inputs cause increased ICC and potential oscillation due to undefined input stage biasing. The device lacks internal pull resistors; external biasing is mandatory for any unterminated input.
Can 74HCT2G16GWH operate at 3.3 V supply?
No - per datasheet Table 6, 74HCT2G16GWH is specified only for 4.5 V to 5.5 V operation. At 3.3 V, VIH minimum (2.0 V) exceeds 60% of VCC, risking unreliable HIGH detection; VOH also drops below TTL-valid levels. Use 74LVC2G16 instead for 3.3 V systems.
