Product details
Overview
NLV74VHCT32ADTR2G from onsemi is a quad 2-input OR gate with TTL-compatible inputs and full 5.0 V CMOS output swing, designed for logic-level translation between 1.8 V/3.0 V and 5.0 V domains. It operates from 2.0 V to 5.5 V, delivers 3.8 ns typical propagation delay at 5.0 V, supports ±25 mA output drive, and features input overvoltage tolerance up to 7.0 V - enabling safe interfacing of mixed-voltage systems in automotive control modules.
For engineers reviewing the NLV74VHCT32ADTR2G datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q100 qualification, 125°C max operating temperature, TSSOP-14 package, input protection during hot insertion, and guaranteed noise immunity via buffered output stage.
Technical Context
The NLV74VHCT32ADTR2G implements four independent OR gates using silicon-gate CMOS technology, achieving bipolar-Schottky TTL speed while maintaining CMOS power efficiency. Its three-stage internal structure includes an output buffer that enhances noise immunity and stabilizes switching behavior under capacitive loads.
Input thresholds (VIL = 0.8 V, VIH = 2.0 V) ensure compatibility with legacy LSTTL logic, while the output swings rail-to-rail (0 V to VCC) across 2.0–5.5 V supply range. Input protection allows safe operation with Vin up to 7.0 V regardless of VCC, and outputs remain protected even when VCC = 0 V - critical for battery-backup and hot-swap scenarios.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 3.8 ns typ @ VCC = 5.0 V, CL = 15 pF - enables high-speed signal combining in timing-critical control paths |
| Supply Voltage Range | 2.0 V to 5.5 V - supports dual-supply systems and brown-out tolerant designs |
| Input Voltage Tolerance | −0.5 V to +7.0 V - permits direct connection to 5 V buses without level-shifting circuitry when powered from 3.3 V or lower |
| Output Drive | ±25 mA per pin - sufficient to drive multiple standard CMOS/TTL loads or small LEDs directly |
| Operating Temperature | −55°C to +125°C - meets automotive under-hood and industrial ambient requirements |
| ESD Rating | HBM > 2000 V - reduces risk of field failure during handling and assembly |
| Quiescent ICC | 2.0 µA max @ TA = 25°C - enables ultra-low-power standby modes in always-on subsystems |
Pinout & Package
TSSOP-14 (DT suffix, Case 948G), 4.4 mm × 5.0 mm body, 0.65 mm pitch, exposed pad not present, RoHS-compliant Pb-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 8, 9, 12, 13 | Input A/B of OR gates | Dual-input logic ports accepting TTL- or CMOS-level signals; tolerant to 7.0 V regardless of VCC |
| 3, 6, 10, 11 | Output Y of OR gates | CMOS-rail output capable of sourcing/sinking ±25 mA; protected against back-drive when VCC = 0 V |
| 7 | GND | Ground reference for all inputs, outputs, and internal circuitry; must be low-impedance for noise immunity |
| 14 | VCC | Primary power supply (2.0–5.5 V); powers internal buffer and output stage; decoupling required near pin |
Key Features
| Feature | Design Value |
|---|---|
| Logic-Level Translation | Enables bidirectional voltage translation (e.g., 3.3 V logic → 5.0 V domain) without external resistors or translators |
| Hot-Insertion Safe I/O | Input/output structures remain functional and undamaged during live insertion into powered backplanes or modules |
| AEC-Q100 Qualified | Validated for automotive applications including engine control, body electronics, and ADAS sensor interfaces |
| Balanced Propagation Delays | tPLH ≈ tPHL ensures symmetrical rise/fall timing - critical for glitch-free combinatorial logic in safety-critical paths |

Equivalent & Alternatives
The following parts are listed as comparable options for similar OR gate logic-level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC74VHCT32ADTR2G | Same pinout, same electrical specs, but rated for −40°C to +85°C industrial temp range only | Lacks AEC-Q100 qualification and extended temperature support | Select when automotive qualification and 125°C operation are not required |
| SN74LVC32APWRE4 | 3.3 V only (1.65–3.6 V), no 5 V output swing; 3.5 ns typ tPD at 3.3 V | Not suitable for 5 V logic domains or mixed-voltage translation | Choose only for pure 3.3 V systems requiring lowest propagation delay |
Compared with MC74VHCT32ADTR2G and SN74LVC32APWRE4, the NLV74VHCT32ADTR2G uniquely combines AEC-Q100 compliance, 125°C operation, and true 5.0 V CMOS output capability - making it the sole option among the three for automotive-grade 5 V interface consolidation.

FAQ
What is the maximum input voltage the NLV74VHCT32ADTR2G can tolerate?
The NLV74VHCT32ADTR2G supports DC input voltages from −0.5 V to +7.0 V, independent of VCC level. This allows safe connection to 5.0 V signal sources even when powered from 3.3 V or 2.5 V supplies - a key enabler for logic-level translation without external components. The NLV74VHCT32ADTR2G input protection circuitry prevents damage during overvoltage events such as hot insertion or supply sequencing mismatches.
Is the NLV74VHCT32ADTR2G pin-compatible with standard 74-series OR gates?
Yes, the NLV74VHCT32ADTR2G uses the industry-standard SOIC-14 and TSSOP-14 footprints and matches the pinout of 74HC32, 74HCT32, and MC74VHCT32A devices. All four OR gates, power, and ground pins align identically - enabling drop-in replacement in existing designs. The NLV74VHCT32ADTR2G maintains identical logic function, truth table, and terminal assignments as legacy 74-series equivalents.
Does the NLV74VHCT32ADTR2G support operation at 2.0 V supply?
Yes, the NLV74VHCT32ADTR2G is fully specified from 2.0 V to 5.5 V. At 2.0 V, it maintains valid logic thresholds (VIL ≤ 0.53 V, VIH ≥ 1.2 V) and delivers functional output swing, enabling use in ultra-low-power battery-backed subsystems. The NLV74VHCT32ADTR2G quiescent current remains below 2.0 µA at 25°C, supporting multi-year operation in energy-constrained applications.
What automotive qualifications does the NLV74VHCT32ADTR2G hold?
The NLV74VHCT32ADTR2G carries the NLV prefix indicating AEC-Q100 qualification for automotive applications, with testing performed across −55°C to +125°C operating range and PPAP documentation capability. It meets stress test requirements for thermal cycling, humidity, and ESD (HBM > 2000 V), and is manufactured in onsemi's qualified automotive sites. The NLV74VHCT32ADTR2G is intended for use in body electronics, chassis, and infotainment systems where reliability under harsh conditions is mandatory.
Can the NLV74VHCT32ADTR2G outputs drive multiple TTL loads?
Yes, each output of the NLV74VHCT32ADTR2G can source or sink up to ±25 mA, exceeding the ±4 mA requirement of standard LS-TTL loads. At VCC = 5.0 V, VOH ≥ 2.9 V and VOL ≤ 0.44 V under 4 mA load - ensuring solid logic-high and logic-low margins across multiple fanouts. The NLV74VHCT32ADTR2G buffered output stage also maintains signal integrity when driving 50 pF loads, supporting reliable operation in dense PCB layouts.
