Product details
Overview
74HCT2G16GV from Nexperia is a dual non-inverting buffer gate in SC-74 (TSOP6) package, designed for level-shifting and signal conditioning in 5 V digital systems. It delivers two independent CMOS buffers with 4.5 V to 5.5 V supply operation, <18 ns propagation delay at VCC = 4.5 V/CL = 50 pF, ±4 mA output drive, and guaranteed operation from –40 °C to +125 °C - used in industrial I/O expansion and microcontroller peripheral interfacing.
For engineers reviewing the 74HCT2G16GV datasheet, 74HCT2G16GV pinout, 74HCT2G16GV application, or 74HCT2G16GV equivalent, key selection criteria include TTL-compatible input thresholds (VIH = 2.0 V min), low static current (<20 μA at 125 °C), ESD robustness (HBM >2000 V), and dual-channel isolation for noise-sensitive bus buffering.
Technical Context
This device implements two independent, unidirectional CMOS buffer stages with TTL-compatible input logic thresholds and rail-to-rail CMOS output swing. Its input structure accepts standard TTL voltage levels while driving CMOS loads with balanced rise/fall times and no internal feedback or latch-up risk.
It operates strictly as a combinatorial logic element - no internal clock, memory, or state retention. All timing parameters are specified under defined load (CL = 50 pF) and supply (VCC = 4.5 V) conditions, with propagation delay (tpd) and transition time (tt) separately characterized for each channel.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures compatibility with standard 5 V TTL logic domains and stable operation across industrial temperature range. |
| Propagation Delay | 10–29 ns (VCC = 4.5 V, CL = 50 pF) - enables reliable timing in high-speed digital control paths up to ~30 MHz toggle rate. |
| Output Drive | ±4.0 mA (VOH/VOL @ VCC = 4.5 V) - sufficient to drive multiple 74-series inputs or moderate PCB trace capacitance without signal degradation. |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max - guarantees clean recognition of TTL-level signals without external level translation. |
| ESD Rating | HBM >2000 V, CDM >1000 V - meets JEDEC JS-001/JS-002 Class 2/C3 for robust handling in automated assembly and field environments. |
| Operating Temp | –40 °C to +125 °C - qualified for under-hood, motor control, and industrial PLC applications without derating. |
Pinout & Package
74HCT2G16GV uses the SOT457 (SC-74; TSOP6) plastic surface-mounted package: 6-pin, 1.7 mm body width, 0.65 mm lead pitch, and pin 1 indicator located below marking code on lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First buffer input - accepts TTL-compatible logic signals; high-impedance CMOS input with ≤1.0 μA leakage at 125 °C. |
| 2 | GND | Ground reference - must be connected directly to system ground plane to ensure noise immunity and output voltage accuracy. |
| 3 | 2A | Second buffer input - electrically isolated from 1A; enables independent signal routing without crosstalk. |
| 4 | 2Y | Second buffer output - provides inverted-phase-complementary drive to 1Y; supports fan-out to ≥10 74HC inputs. |
| 5 | VCC | Positive supply - requires local 100 nF ceramic decoupling within 5 mm to suppress switching noise and maintain VIH/VIL margins. |
| 6 | 1Y | First buffer output - delivers true (non-inverted) logic level with rail-to-rail swing and matched drive strength to 2Y. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | Operates from 4.5 V to 5.5 V - eliminates need for dedicated LDO when interfacing with 5 V rails in mixed-voltage systems. |
| Balanced Propagation Delays | tpd matching ≤3 ns between channels - critical for synchronized enable/control signals in dual-path peripherals. |
| Unlimited Input Edge Rates | No minimum rise/fall time requirement - compatible with slow-switching sensors and fast FPGA outputs without waveform distortion. |
| High Noise Immunity | Input hysteresis not present, but VIH/VIL separation >1.2 V at VCC = 5 V - rejects common-mode noise up to ±0.6 V on shared PCB traces. |
| Low Static Power | ICC ≤20 μA at +125 °C - enables use in always-on monitoring circuits without thermal or battery-life penalty. |
Applications
| Industrial Sensor Interface | Microcontroller GPIO Expansion |
|---|---|
|
Use Scenario: Isolating analog sensor ADC enable lines from noisy 24 V PLC backplane. IC Role / Device Role / Timing Role: Dual buffer provides galvanically separated, slew-rate-controlled enable pulses to two independent ADCs. Use Value: Prevents cross-talk-induced sampling errors by eliminating capacitive coupling between adjacent enable paths. |
Use Scenario: Extending limited GPIO count on an ARM Cortex-M0+ MCU for LED status indicators and pushbutton inputs. IC Role / Device Role / Timing Role: Buffers translate weak MCU output drive into robust 4 mA signals capable of driving multiple LEDs in parallel. Use Value: Eliminates need for discrete transistors or additional logic, reducing BOM count and PCB area by 30% vs. discrete solution. |
| Legacy Bus Level Translation | Motor Driver Enable Conditioning |
|
Use Scenario: Interfacing 3.3 V FPGA control signals to 5 V legacy parallel bus peripherals (e.g., EPROM, LCD controller). IC Role / Device Role / Timing Role: Acts as unidirectional level shifter with TTL-compatible input and full 5 V CMOS output swing. Use Value: Avoids timing skew and shoot-through risk inherent in bidirectional translators, ensuring deterministic bus access timing. |
Use Scenario: Conditioning PWM enable signals sent from a safety-critical MCU to dual H-bridge motor drivers. IC Role / Device Role / Timing Role: Provides glitch-free, noise-filtered enable gating with matched propagation delay across both motor channels. Use Value: Guarantees simultaneous activation of left/right motor drivers, preventing torque imbalance during startup. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC2G16GV | Wider supply range (1.65–5.5 V), lower VIH (1.5 V min), higher speed (tpd = 3.2 ns typ @ 3.3 V), but only rated to +85 °C. | Suitable for 3.3 V portable systems; unsuitable for automotive under-hood or industrial high-temp environments. | Select when operating at 3.3 V with tight timing budgets and ambient ≤85 °C. |
| SN74LVC2G16DBVR | Same logic function and 3.3 V specs as 74LVC2G16GV, but in SOT-23-6 package with different pinout (VCC/GND swapped vs. SOT457) and lower ESD rating (HBM = 2 kV). | Requires PCB redesign due to incompatible footprint and pin mapping; lacks extended temperature qualification. | Choose only if existing design uses TI's SOT-23-6 layout and 125 °C operation is not required. |
Compared with 74HCT2G16GV, 74LVC2G16GV offers superior speed and voltage flexibility but sacrifices high-temperature reliability, while SN74LVC2G16DBVR introduces mechanical and ESD compromises without functional advantage - making 74HCT2G16GV the optimal choice for ruggedized 5 V industrial control.

FAQ
Is 74HCT2G16GV pin-compatible with 74HC2G16GV?
Yes - both share identical SOT457 (SC-74) package, pinout, and functional behavior. The key difference is input threshold: 74HCT2G16GV accepts TTL levels (VIH ≥2.0 V), while 74HC2G16GV requires CMOS levels (VIH ≥3.15 V at VCC = 4.5 V). Substitution is safe only if driving source is TTL-compatible.
Can 74HCT2G16GV operate at 3.3 V supply?
No - its recommended operating range is strictly 4.5 V to 5.5 V. At 3.3 V, VIH specification (2.0 V min) exceeds 60% of VCC, violating input margin requirements and risking unreliable HIGH detection. Use 74LVC2G16GV instead for 3.3 V systems.
What is the maximum capacitive load this device can drive reliably?
Rated for CL = 50 pF per output in timing specifications. With 4 mA drive capability, it can reliably drive up to 100 pF while maintaining tpd <35 ns and VOL <0.4 V at VCC = 4.5 V. Beyond 100 pF, add series termination or buffer staging to prevent overshoot and timing violations.
Does 74HCT2G16GV support hot insertion or live swapping?
No - it lacks power-up/down protection circuitry such as Ioff or partial-power-down mode. Applying signal inputs before VCC stabilization may cause latch-up or excessive ICC. Always sequence VCC before applying inputs, especially in backplane or modular systems.
