Product details

Overview

74ALVC125PW,118 from Nexperia is a quad non-inverting 3-state buffer/line driver in TSSOP14 package, operating from 1.65 V to 3.6 V supply, featuring Schmitt-trigger inputs for noise immunity, IOFF partial power-down protection, and -40 °C to +125 °C temperature rating-used in bus isolation and level translation in industrial control backplanes.

For engineers reviewing the 74ALVC125PW,118 datasheet, 74ALVC125PW,118 pinout, 74ALVC125PW,118 application, or 74ALVC125PW,118 equivalent, key selection criteria include 3-state timing (tpd ≤ 3.2 ns at 3.6 V), IOFF leakage (< ±80 μA at VCC = 0 V), input overvoltage tolerance (3.6 V), and thermal performance in TSSOP14 (7.3 mW/K derating above 81 °C).

Technical Context

This device implements four independent non-inverting buffers, each with active-low 3-state enable (nOE) controlling high-impedance output states. Schmitt-trigger inputs ensure robust operation with slow-rising signals, while the IOFF circuit disables outputs during power-down to prevent backflow current.

It complies with JEDEC standards JESD8-7 (1.65–1.95 V), JESD8-5 (2.3–2.7 V), and JESD8C/JESD36 (2.7–3.6 V), and supports direct TTL-level interfacing across its full voltage range. Static and dynamic parameters are fully characterized from -40 °C to +125 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	1.65 V to 3.6 V - enables single-supply operation across 1.8 V, 2.5 V, and 3.3 V logic domains.
Propagation Delay (tpd)	≤ 3.2 ns at VCC = 3.6 V - ensures sub-4 ns signal path timing for high-speed bus buffering.
IOFF Leakage Current	< ±80 μA at VCC = 0 V - prevents damaging backflow when powered down in mixed-voltage systems.
Input Voltage Tolerance	Up to 3.6 V - allows safe interfacing with higher-voltage peripherals without level shifters.
Operating Temperature	-40 °C to +125 °C - qualified for extended industrial and under-hood applications.
ESD Protection	HBM > 2000 V, CDM > 1000 V - meets robustness requirements for automated assembly and field use.
Power Dissipation (Ptot)	500 mW at Tamb ≤ 81 °C (TSSOP14) - supports continuous operation in thermally constrained PCB layouts.

Pinout & Package

TSSOP14 package (SOT402-1): plastic thin shrink small outline, 14 leads, body width 4.4 mm, 0.65 mm pitch, 0.8 mm max height - optimized for high-density routing and thermal performance in industrial PCBs.

Pin/Terminal	Circuit Role	Design Meaning
1, 4, 10, 13	nOE (active LOW)	Independent enable control per buffer; drives output to high-impedance when HIGH.
2, 5, 9, 12	nA (input)	Non-inverting data input with Schmitt-trigger threshold for noise margin on slow edges.
3, 6, 8, 11	nY (output)	3-state buffered output; sinks/source up to ±24 mA at 3.0 V with VOL ≤ 0.55 V.
7	GND	Reference ground for all I/O and internal logic; requires low-impedance PCB connection.
14	VCC	Primary supply rail; decoupling capacitor (100 nF) recommended within 5 mm of pin.

Key Features

Feature	Design Value
Wide Supply Range	1.65 V to 3.6 V - eliminates need for separate voltage rails when interfacing 1.8 V, 2.5 V, and 3.3 V subsystems.
Schmitt-Trigger Inputs	Input hysteresis ≥ 0.3 V at VCC = 3.3 V - rejects noise on long traces or unterminated buses.
IOFF Partial Power-Down	Output disabled with VCC = 0 V; IOFF leakage < ±10 μA typical - prevents backfeed in hot-swap or multi-rail systems.
Latch-Up Immunity	> 250 mA per JESD78 Class II.A - ensures reliability in electrically noisy industrial environments.
Thermal Enhancement	TSSOP14 package derates at 7.3 mW/K above 81 °C - supports sustained operation in enclosed enclosures.

Use Scenario: Routing digital stimulus signals from pattern generators to DUT pins while maintaining signal integrity across multiple channels.

IC Role / Device Role / Timing Role: Level-translating line driver with 3.6 V-tolerant inputs; tpd ≤ 3.2 ns preserves timing margins in 100 MHz test vectors.

Use Value: Eliminates external level shifters and reduces channel skew via matched propagation delays across all four buffers.

Programmable Logic Interface

Industrial Sensor Hub Data Aggregation

Use Scenario: Interfacing FPGA I/O banks (1.8 V or 2.5 V) with legacy 3.3 V peripheral modules in modular PLC I/O cards.

IC Role / Device Role / Timing Role: Non-inverting voltage-level translator with bidirectional 3-state capability; VIH = 2.0 V min at VCC = 3.3 V.

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad 3-state buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC125APWR	TI part; identical pinout and function but lacks IOFF specification; max VCC = 3.6 V, same temp range.	No guaranteed power-down isolation; unsuitable where backflow current must be blocked during VCC ramp-down.	Select only if IOFF is not required and TI sourcing preference applies.
74LVC125AD,118	Nexperia SO14 variant (SOT108-1); same electrical specs but larger footprint and higher thermal resistance (10.1 mW/K derating).	Preferred for prototyping or legacy through-hole-compatible designs; lower density than TSSOP14.	Choose for manual assembly, rework ease, or compatibility with existing SO14 footprints.

Compared with SN74LVC125APWR, 74ALVC125PW,118 adds critical IOFF protection for partial power-down safety; versus 74LVC125AD,118, it delivers 25 % smaller board area and improved thermal derating for compact industrial modules.

FAQ

Does 74ALVC125PW,118 support hot insertion in live backplanes?

Yes-it features IOFF circuitry that actively disables outputs when VCC = 0 V, limiting backflow current to < ±80 μA. This prevents damage during hot-plug events in modular industrial systems, provided GND is connected before VCC and signal lines.

Can this device drive 50 Ω transmission lines directly?

No-its output drive strength (±24 mA at 3.0 V) is rated for capacitive loads up to 50 pF, not 50 Ω DC termination. For impedance-matched line driving, use an external series resistor (e.g., 33 Ω) or dedicated line driver ICs like SN65LVDSx.

What is the maximum clock frequency supported for data buffering?

While not a clock device, its 3.2 ns max propagation delay at 3.6 V supports data rates up to ~300 Mbps in NRZ signaling (assuming 1 UI ≥ 2 × tpd). Real-world limit depends on load capacitance and signal integrity-verified up to 200 MHz with 30 pF load in Nexperia's test setup.

Is the TSSOP14 package lead-free and RoHS compliant?

Yes-74ALVC125PW,118 is manufactured in a lead-free, halogen-free process and fully complies with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with Sb, Br, Cl, F, and P concentrations below threshold limits.
