Product details

Overview

74AHC1G125GZYL from Nexperia is a single CMOS bus buffer/line driver with 3-state output, overvoltage-tolerant inputs (up to 5.5 V), operating from 2.0 V to 5.5 V supply, and specified for -40 °C to +125 °C. It functions as a level-translating unidirectional buffer in mixed-voltage I/O interfaces, enabling signal integrity between 1.8 V/2.5 V logic domains and 3.3 V/5 V buses.

For engineers reviewing the 74AHC1G125GZYL datasheet, 74AHC1G125GZYL pinout, 74AHC1G125GZYL application, or 74AHC1G125GZYL equivalent, this device is selected for low-power, high-noise-immunity bidirectional bus control in space-constrained embedded systems requiring thermal-enhanced XSON5 packaging and side-wettable flanks for automated optical inspection (AOI) and solder joint reliability.

Technical Context

This device implements a single-channel non-inverting buffer with active-low 3-state enable (OE), supporting translation between disparate supply domains via overvoltage-tolerant inputs independent of V_CC. Its symmetrical output impedance ensures matched rise/fall times and balanced propagation delays (e.g., 3.4 ns typ at V_CC = 5.0 V, C_L = 15 pF).

The logic function follows standard truth table behavior: when OE = LOW, Y = A; when OE = HIGH, Y = high-impedance. Input leakage remains ≤0.1 μA across temperature, and static drive capability delivers VOH ≥ 3.94 V at IO = −8.0 mA (V_CC = 4.5 V), ensuring robust TTL- and CMOS-compatible interfacing.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply voltage	2.0 V to 5.5 V - supports direct interface with 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without level shifters.
Input voltage tolerance	Up to 5.5 V - enables use as a translator in mixed-voltage systems where input signals exceed V_CC.
Propagation delay	3.4 ns (typ) at V_CC = 5.0 V, C_L = 15 pF - ensures timing-critical bus buffering with minimal latency.
Output drive strength	±8.0 mA - sufficient to drive standard 50 pF loads and multiple CMOS/TTL inputs on shared buses.
Operating temperature	−40 °C to +125 °C - qualified for under-hood automotive modules, industrial PLCs, and extended-temperature power management subsystems.
Power dissipation	250 mW max (derated above 72 °C) - enables continuous operation in thermally dense PCB layouts with XSON5's thermal-enhanced SWF package.
ESD protection	HBM > 2000 V, CDM > 1000 V - meets IEC 61000-4-2 system-level ESD immunity requirements for end-equipment interfaces.

Pinout & Package

XSON5 plastic thermal-enhanced extremely thin small outline package with side-wettable flanks (SWF); no leads; 5 terminals; body dimensions 1.1 × 0.85 × 0.5 mm (SOT8065-1). Optimized for AOI compatibility and high-yield reflow soldering in fine-pitch applications.

Pin/Terminal	Circuit Role	Design Meaning
GND	Ground reference	Primary return path for all internal logic and output current; must be low-impedance and adjacent to V_CC for noise suppression.
V_CC	Supply voltage	CMOS core and I/O supply rail; decoupling capacitor (100 nF) required within 3 mm for stable switching performance.
Y	Data output	3-state buffered output; presents high-impedance (Z) when OE is HIGH, otherwise replicates A with CMOS-level swing.
OE	Output enable (active-low)	Asynchronous control input; asserts buffer output when LOW; tolerant to 5.5 V regardless of V_CC level.
A	Data input	CMOS-level input with overvoltage tolerance; accepts logic HIGH up to 5.5 V even when V_CC = 2.0 V.

Key Features

Feature	Design Value
Wide supply range	2.0 V to 5.5 V enables drop-in replacement across legacy and modern logic families without redesign.
Overvoltage-tolerant inputs	Inputs withstand 5.5 V regardless of V_CC, eliminating external clamping diodes in mixed-voltage interconnects.
Symmetrical output impedance	Matched pull-up/pull-down strength ensures <10% duty-cycle distortion on clock or data lines driving capacitive loads.
Thermal-enhanced XSON5	SOT8065-1 package with side-wettable flanks supports automated optical inspection and improves thermal resistance by 15% vs. SOT753.
High noise immunity	VIH/VIL thresholds defined at 70%/30% of V_CC provide >0.8 V noise margin at 3.3 V operation, reducing false triggering.

Applications

Use Scenario: Isolating 1.8 V sensor ADC outputs from a 3.3 V microcontroller bus while maintaining signal integrity across noisy chassis ground.

IC Role / Device Role / Timing Role: Unidirectional level-translating buffer with 3-state control for time-multiplexed sensor readout sequences.

Use Value: Eliminates need for discrete level shifters; overvoltage tolerance prevents latch-up during ESD events on sensor harnesses.

Use Scenario: Driving LIN transceiver enable lines from a 5 V MCU GPIO while sharing PCB space with high-current solenoid drivers.

IC Role / Device Role / Timing Role: Low-latency bus buffer providing clean enable/disable transitions with sub-10 ns propagation delay.

Use Value: XSON5 thermal enhancement sustains reliable operation at 125 °C ambient; side-wettable flanks ensure solder joint reliability in vibration-prone environments.

Portable Medical Device Bus

Use Scenario: Interfacing ultra-low-power 2.5 V PMIC status signals to a 3.3 V application processor I²C/SPI bus in battery-powered diagnostic equipment.

IC Role / Device Role / Timing Role: CMOS-compatible buffer with <1 μA ICC standby current, enabling always-on monitoring without compromising battery life.

Use Value: 2.0 V minimum V_CC allows operation during brown-out conditions; high noise immunity rejects RF interference from nearby wireless radios.

Use Scenario: Controlling enable signals for multiple DC-DC converters in a compact smart home hub, where board area and thermal density are constrained.

Equivalent & Alternatives

The following parts are listed as comparable options for similar bus buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
74AHC1G125GV	SC-74A (SOT753) package; no side-wettable flanks; higher thermal resistance (3.8 mW/K derating above 85 °C).	Less suitable for AOI-based production or high-reliability automotive applications requiring solder joint verification.	Select GV only if legacy footprint compatibility or lower cost outweighs thermal and inspection advantages of GZYL.
74AHCT1G125GZ	TTL-input thresholds (VIH = 2.0 V min); identical XSON5 package and pinout; same 3-state functionality.	Better suited for interfacing with legacy 5 V TTL outputs; not recommended for pure CMOS systems due to reduced noise margin at low V_CC.	Choose AHCT variant only when driving from 5 V TTL sources; otherwise AHC offers superior noise immunity and wider V_CC flexibility.

Compared with 74AHC1G125GV, the GZYL offers superior thermal performance and AOI support; compared with 74AHCT1G125GZ, it provides broader supply range and higher noise immunity-making GZYL optimal for new designs prioritizing flexibility and manufacturability.

FAQ

What is the maximum input voltage the 74AHC1G125GZYL can tolerate?

The 74AHC1G125GZYL features overvoltage-tolerant inputs rated to 5.5 V regardless of V_CC level, allowing safe interfacing with higher-voltage signals in mixed-supply systems without external protection components. This specification is verified per datasheet Table 5 (Limiting Values) and applies across the full −40 °C to +125 °C operating range.

Does the 74AHC1G125GZYL support hot-swap or live-insertion?

No, the 74AHC1G125GZYL is not designed for hot-swap operation. Its absolute maximum ratings require V_CC to be established before applying input signals, and the device lacks built-in current limiting or slew-rate control for insertion into live backplanes. Safe operation requires power sequencing where V_CC is stable prior to asserting A or OE.

Can the 74AHC1G125GZYL drive a 50 pF load at 10 MHz?

Yes. At V_CC = 5.0 V and C_L = 50 pF, the typical propagation delay is 4.8 ns and output drive strength is ±8.0 mA, enabling reliable 10 MHz toggling with margin. Dynamic power dissipation is calculated as PD = CPD × V_CC² × f = 9 pF × 25 V² × 10 MHz = 2.25 mW, well within the 250 mW thermal limit.

Is the 74AHC1G125GZYL pin-compatible with the 74AHCT1G125GZ?

Yes-both devices share identical XSON5 (SOT8065-1) pinout, mechanical footprint, and terminal assignment (GND, V_CC, Y, OE, A). However, input threshold logic differs: AHC uses CMOS levels (VIH ≈ 0.7×V_CC), while AHCT uses TTL levels (VIH = 2.0 V min), requiring careful signal source compatibility verification.
