Product details

Overview

74HCT3G07DP,125 from Nexperia is a triple non-inverting buffer IC with open-drain outputs, designed for level-shifting and wired-OR logic applications in mixed-voltage systems. It operates from 4.5 V to 5.5 V, supports TTL-compatible inputs, delivers ≤0.33 V low-level output at 4.0 mA load, and is qualified from −40 °C to +125 °C in TSSOP8 (SOT505-2) package - commonly used in I²C bus buffering and GPIO expansion circuits.

For engineers reviewing the 74HCT3G07DP,125 datasheet, 74HCT3G07DP,125 pinout, 74HCT3G07DP,125 application, or 74HCT3G07DP,125 equivalent, key selection criteria include open-drain drive capability, TTL input threshold compatibility, propagation delay under 27 ns at 4.5 V, and thermal performance in high-density PCB layouts.

Technical Context

This device implements three independent non-inverting buffers, each with an open-drain output stage enabling external pull-up configuration and voltage-level translation. Input clamp diodes allow safe interfacing to signals exceeding VCC when current-limiting resistors are used.

It adheres to JEDEC JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V) standards, features ±2000 V HBM ESD protection, and maintains stable operation across industrial and extended temperature ranges without requiring internal pull-ups or enable controls.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	4.5 V to 5.5 V - ensures compatibility with 5 V TTL logic domains and robust noise margin
Input Threshold	V_IL ≤ 0.8 V, V_IH ≥ 2.0 V - guarantees reliable recognition of standard TTL logic levels
Output Drive	4.0 mA sink at V_OL ≤ 0.33 V - supports direct connection to 3.3 V or 5 V pull-ups with defined low-state voltage
Propagation Delay	t_PZL/t_PLZ ≤ 32 ns at V_CC = 4.5 V - enables use in medium-speed digital control and status signaling
Operating Temperature	−40 °C to +125 °C - validated for under-hood automotive modules and industrial motor controllers
ESD Protection	HBM > 2000 V, CDM > 1000 V - reduces risk of field failure during handling and board assembly
Input Leakage	±1.0 μA max at V_CC = 5.5 V - minimizes loading on high-impedance source nodes like microcontroller GPIOs

Pinout & Package

TSSOP8 plastic thin shrink small outline package (SOT505-2), 3 mm body width, 0.65 mm lead pitch, 0.5 mm lead length - optimized for automated placement and thermal dissipation in space-constrained designs.

Pin/Terminal	Circuit Role	Design Meaning
1, 3, 6	1A / 2A / 3A	Independent logic inputs - accept TTL-level signals; each includes clamp diodes for overvoltage tolerance
2, 5, 7	3Y / 1Y / 2Y	Open-drain outputs - require external pull-up; support wired-OR, I²C, and level-shifted bus interfaces
4	GND	Ground reference - must be low-impedance return path for all output sink currents
8	V_CC	Positive supply - powers internal logic; also defines high-level reference for input thresholds

Key Features

Feature	Design Value
Triple independent buffers	Enables consolidation of three discrete open-drain drivers into one compact footprint, reducing BOM count and routing complexity
TTL-compatible inputs	Eliminates need for external level translators when interfacing with legacy 5 V microcontrollers or peripheral ICs
Clamp diode protected inputs	Permits safe connection to voltages up to V_CC + 0.5 V using series resistors - critical for hot-swap and mixed-rail systems
−40 °C to +125 °C qualification	Validated for use in engine control units, power inverters, and outdoor industrial gateways without derating
Low static current	ICC ≤ 20 μA per input at V_CC = 5.5 V - preserves battery life in always-on monitoring subsystems

Applications

I²C Bus Buffering

GPIO Expansion Interface

Use Scenario: Isolating multiple I²C slave devices on a shared bus to prevent capacitive loading-induced signal degradation and timing violations.

IC Role / Device Role / Timing Role: Acts as a passive repeater with open-drain outputs, preserving bidirectional SDA/SCL protocol behavior while segmenting bus capacitance.

Use Value: Enables reliable communication across 2+ meter cable runs or >10 slave nodes by limiting segment capacitance to <400 pF per side.

Use Scenario: Extending microcontroller GPIO count via software-configurable open-drain outputs driving LEDs, relays, or interrupt lines.

IC Role / Device Role / Timing Role: Provides three additional programmable sink outputs compatible with 3.3 V or 5 V pull-ups, decoupling MCU I/O from load transients.

Use Value: Eliminates need for discrete MOSFETs or driver ICs when sinking ≤4 mA per channel - reducing component count and layout area.

Level-Shifting Logic Interface

Wired-OR Fault Signaling

Use Scenario: Interfacing a 3.3 V FPGA I/O bank to a 5 V sensor subsystem requiring active-low reset or enable signals.

IC Role / Device Role / Timing Role: Translates 3.3 V logic highs to 5 V-compatible low states using external 5 V pull-up; no direction control needed.

Use Value: Achieves rail-to-rail voltage translation without timing skew or power supply sequencing constraints - unlike active translators.

Use Scenario: Aggregating fault alerts from multiple power supplies or motor drivers onto a single system-level "FAULT" line.

IC Role / Device Role / Timing Role: Each buffer output connects to common collector node; any asserted low pulls entire line low (wired-OR).

Use Value: Provides deterministic fail-safe behavior - single-point failure detection without polling or software overhead.

Equivalent & Alternatives

The following parts are listed as comparable options for similar open-drain buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
74LVC3G07GM,125	Lower V_CC range (1.65–5.5 V); CMOS input thresholds; higher speed (t_PZL ≤ 19 ns)	Better suited for 1.8 V/3.3 V mixed-signal systems; less tolerant of 5 V input overdrive	Select when interfacing with low-voltage FPGAs or ASICs and full 5 V TTL compatibility is not required
SN74LVC3G07DCUR	Same logic function; different package (VSSOP8); slightly higher ICC (≤30 μA)	Identical electrical behavior but tighter 2.3 mm body width - preferred for ultra-dense layouts	Choose when board space is constrained and Nexperia's TSSOP8 footprint conflicts with existing land patterns

Compared with 74HCT3G07DP,125, the 74LVC3G07GM,125 offers broader voltage flexibility at the cost of reduced 5 V input robustness, while SN74LVC3G07DCUR provides identical functionality in a smaller VSSOP8 package - making both viable where TTL-level input compatibility or TSSOP8 mechanical fit are secondary concerns.

FAQ

Can 74HCT3G07DP,125 drive a 10 kΩ pull-up to 5 V?

Yes - its open-drain output is rated for 4.0 mA sink current with V_OL ≤ 0.33 V at V_CC = 4.5 V. With a 10 kΩ pull-up to 5 V, the worst-case low-state voltage is 0.33 V, well within standard TTL and CMOS input thresholds. No additional buffering is required.

Does this IC require external pull-up resistors on all outputs?

Yes - all three outputs (1Y, 2Y, 3Y) are open-drain and lack internal pull-ups. External pull-up resistors must be connected to each output to establish HIGH logic state; values are selected based on bus capacitance, rise time requirements, and sink current limits.

Is 74HCT3G07DP,125 pin-compatible with 74HC3G07DP,125?

Yes - both share identical TSSOP8 (SOT505-2) pinout and functional diagram. The only difference is input threshold: 74HCT3G07DP,125 accepts TTL levels (V_IH ≥ 2.0 V), while 74HC3G07DP,125 requires CMOS levels (V_IH ≥ 3.15 V at V_CC = 4.5 V). Electrical substitution is possible if source logic meets the stricter HC threshold.

What is the maximum capacitive load this device can drive reliably?

Based on dynamic characteristics and test conditions in the datasheet, it reliably drives ≤50 pF loads with t_PZL/t_PLZ ≤ 32 ns at V_CC = 4.5 V. For larger loads (e.g., >100 pF), propagation delay increases nonlinearly; design validation with actual trace and connector capacitance is recommended.
