Product details
Overview
74HC1G126GW,125 from Nexperia is a single 3-state bus buffer/line driver in TSSOP5 (SOT353-1) package, operating from 2.0 V to 6.0 V supply, with CMOS input levels, ±35 mA output drive, and propagation delay as low as 9 ns at VCC = 6.0 V - used for bidirectional data isolation in low-pin-count interface expansion circuits.
For engineers reviewing the 74HC1G126GW,125 datasheet, 74HC1G126GW,125 pinout, 74HC1G126GW,125 application, or 74HC1G126GW,125 equivalent, this device serves as a compact, rail-to-rail compatible unidirectional buffer enabling controlled signal routing in space-constrained logic interfaces, especially where power efficiency and high noise immunity are required.
Technical Context
This device implements a single non-inverting buffer with active-low 3-state enable control (OE), supporting TTL-compatible output drive while accepting CMOS-level inputs. Its internal structure includes input clamp diodes enabling safe interfacing to voltages exceeding VCC when current-limiting resistors are used.
It operates across industrial and extended temperature ranges (−40 °C to +125 °C), complies with JESD7A and JESD8C standards, and delivers symmetrical output impedance with balanced tPLH/tPHL propagation delays - critical for timing-critical signal conditioning in mixed-voltage systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - supports direct interfacing with 3.3 V and 5 V logic domains without level shifters. |
| Propagation Delay (A→Y) | 9 ns typical at VCC = 6.0 V, CL = 50 pF - enables sub-100 MHz signal routing in compact logic paths. |
| Output Drive Current | ±35 mA - sufficient to drive multiple standard CMOS loads or short PCB traces without external buffering. |
| Input Thresholds (VCC = 4.5 V) | VIH = 3.15 V min, VIL = 1.35 V max - ensures robust noise margin (>1.3 V) under worst-case voltage and temperature. |
| 3-State Leakage (IOZ) | ≤10 μA at VCC = 6.0 V - guarantees minimal bus contention during disable state in shared-data-line applications. |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood, industrial control, and high-reliability embedded environments. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - reduces risk of field failure during handling and board assembly. |
Pinout & Package
TSSOP5 (SOT353-1) plastic thin shrink small outline package: 5-lead, 1.25 mm body width, 0.65 mm lead pitch, 1.1 mm height - optimized for automated placement and high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Output Enable input | Active-HIGH control: drives Y to high-impedance when LOW; enables output when HIGH. |
| 2 (A) | Data input | CMOS-level buffered input; clamped to allow safe overvoltage tolerance with series resistor. |
| 3 (GND) | Ground reference | 0 V return path for all internal circuitry and output current sink/source. |
| 4 (Y) | Data output | Non-inverting, 3-state output capable of sourcing/sinking ±35 mA into 50 pF load. |
| 5 (VCC) | Supply voltage | Primary power rail (2.0–6.0 V); powers internal logic and output stage. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range (2.0–6.0 V) | Eliminates need for dedicated voltage translators when interfacing 3.3 V controllers to 5 V peripherals. |
| Symmetrical output impedance | Ensures matched rise/fall times (<1 ns skew) for clean edge integrity in timing-sensitive paths. |
| Input clamp diodes | Permits safe connection to signals up to VCC + 0.5 V using external current-limiting resistors. |
| Latch-up immunity >100 mA | Meets JESD78 Class II Level B - prevents destructive latch-up during transient overvoltage events. |
| Low ICC (≤20 μA at VCC = 6.0 V) | Reduces quiescent power in always-on subsystems such as battery-backed configuration registers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC1G126GV,125 | Lower VCC range (1.65–5.5 V); TTL-compatible inputs; higher speed (tpd = 3.7 ns @ 3.3 V). | Better suited for 1.8 V/3.3 V mixed-signal systems but lacks 6 V tolerance and extended temp rating. | Select when interfacing with 1.8 V FPGAs or low-voltage MCUs where 6 V operation is unnecessary. |
| SN74LVC1G126DBVR | Same VCC range (1.65–5.5 V); identical pinout; slightly higher ICC (max 10 μA vs 20 μA). | Qualified per AEC-Q100 Grade 2 (−40 °C to +105 °C), not +125 °C; no HBM >2000 V rating. | Prefer for automotive cabin applications requiring AEC-Q100 compliance but not extended temperature or high-ESD robustness. |
Compared with 74LVC1G126GV,125 and SN74LVC1G126DBVR, the 74HC1G126GW,125 offers superior voltage flexibility (up to 6 V), guaranteed −40 °C to +125 °C operation, and stronger ESD resilience - making it optimal for industrial and harsh-environment designs where absolute voltage margin and reliability outweigh raw speed.

FAQ
Can 74HC1G126GW,125 operate reliably at 2.0 V supply?
Yes. The datasheet specifies full functionality down to 2.0 V, including VIH ≥1.5 V and VOL ≤0.1 V at IO = 6.0 mA, with propagation delay ≤125 ns. This enables direct use with 2.0 V microcontrollers and energy-harvesting systems without level translation.
What is the maximum capacitive load this buffer can drive without signal degradation?
It is characterized up to 50 pF (per JEDEC test conditions), delivering 9 ns typical tpd at VCC = 6.0 V. Driving >50 pF increases delay nonlinearly and may cause ringing; for 100 pF loads, derate VCC or add series termination to maintain edge fidelity.
Does the OE pin require a pull-up or pull-down resistor in normal operation?
No external bias is required: OE is a standard CMOS input with II ≤1.0 μA. However, in systems where OE floats during power-up, a 100 kΩ pull-down is recommended to ensure Y remains in high-impedance until firmware asserts control.
How does the input clamp diode affect interfacing with 12 V signals?
The internal clamp diodes allow safe connection to voltages up to VCC + 0.5 V. To interface with 12 V signals, use a series current-limiting resistor (e.g., 10 kΩ at VCC = 5 V) to restrict IIK to <±20 mA - verified in Section 8 limiting values.
