Product details
Overview
74LVT32DB,118 from NXP Semiconductors (formerly Philips) is a 3.3 V quad 2-input OR gate logic IC in a 14-pin SSOP package. It delivers propagation delays of 2.6 ns (tPLH) and 3.2 ns (tPHL) at VCC = 3.3 V with CL = 50 pF, supports –40 °C to +85 °C operation, and drives up to 32 mA low-level output current - used in high-speed bus interface and level-shifting logic circuits.
For engineers reviewing the 74LVT32DB,118 datasheet, 74LVT32DB,118 pinout, 74LVT32DB,118 application, or 74LVT32DB,118 equivalent, key selection criteria include its LVT-family 3.3 V CMOS compatibility, guaranteed AC performance across industrial temperature range, input/output voltage tolerance up to 5.5 V, and SSOP-14 footprint for space-constrained board layouts.
Technical Context
The 74LVT32DB,118 implements four independent 2-input OR gates using advanced BiCMOS LVT (Low-Voltage TTL) technology, enabling interoperability between 3.3 V logic and 5 V-tolerant inputs. Its design supports hot-swap capable I/O with ±100 µA off-state output current and 3 pF input capacitance for minimal signal loading.
It operates within a 2.7 V to 3.6 V supply range, meets IEEE/IEC logic symbol standards, and features rail-to-rail input voltage support (0–5.5 V), allowing direct interfacing with legacy 5 V systems without external level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.7 V to 3.6 V - ensures stable operation across noisy or marginally regulated 3.3 V rails |
| tPLH / tPHL | 2.6 ns / 3.2 ns @ VCC = 3.3 V, CL = 50 pF - enables ≤300 MHz toggle rates in synchronous logic paths |
| IOL / IOH | 64 mA / –32 mA - drives standard TTL loads or multiple CMOS inputs without buffering |
| VIH / VIL | 2.0 V / 0.8 V - provides 0.5 V noise margin for robust switching in electrically noisy environments |
| CIN | 3 pF - minimizes capacitive loading on upstream drivers and preserves signal edge integrity |
| Operating Temp | –40 °C to +85 °C - qualified for industrial control, telecom infrastructure, and embedded computing |
Pinout & Package
74LVT32DB,118 is housed in a 14-pin plastic shrink small outline package (SSOP), SOT337-1, with 0.65 mm lead pitch and 5.3 mm body width - optimized for automated assembly and thermal performance in dense PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 9, 10, 12, 13 | An, Bn (Inputs) | Eight dedicated OR gate inputs - grouped as A0/B0 through A3/B3 for four independent 2-input OR functions |
| 3, 6, 8, 11 | Yn (Outputs) | Four buffered OR outputs - Y0 through Y3, each capable of sourcing –32 mA or sinking 64 mA |
| 7 | GND | Ground reference - must be low-impedance connection to minimize ground bounce in high-speed switching |
| 14 | VCC | Positive supply - requires local 3.3 V decoupling (e.g., 100 nF ceramic) adjacent to pin |
Key Features
| Feature | Design Value |
|---|---|
| 5 V-tolerant inputs | Accepts 0–5.5 V input signals while powered from 3.3 V - eliminates need for discrete level translators |
| High drive strength | 64 mA sink capability per output - directly drives LEDs, small relays, or multiple downstream logic gates |
| Low propagation delay | Sub-4 ns max delay across full temperature range - supports timing-critical glue logic in FPGA/CPU interfaces |
| Hot-swap compatible | IOFF ≤ ±100 µA at VCC = 0 V - prevents backfeeding during live insertion or partial power-up sequences |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC32APW | Lower drive (24 mA sink), 1.65–3.6 V VCC range, TSSOP-14 package | Optimized for ultra-low-power portable designs; lacks 5 V-tolerant inputs | Select when system-wide 3.3 V compatibility is guaranteed and power budget is constrained |
| 74ALVC32D | Same 5 V-tolerant inputs, but 1.65–3.6 V VCC range and higher ICC (1.5 mA typical) | Better noise immunity at low VCC; less suitable for mixed-voltage hot-swap scenarios | Prefer when operating near 2.5 V rails or requiring enhanced ESD robustness (±2 kV HBM) |
Compared with 74LVT32DB,118, SN74LVC32APW offers lower static current but sacrifices 5 V tolerance and drive strength, while 74ALVC32D retains input compatibility but increases supply current - making 74LVT32DB,118 optimal for industrial 3.3 V systems interfacing with legacy 5 V peripherals.

FAQ
What is the maximum input voltage rating for 74LVT32DB,118?
The 74LVT32DB,118 supports DC input voltages from –0.5 V to +7.0 V, with guaranteed 5 V tolerance (0–5.5 V) under normal operating conditions. This allows safe interfacing with 5 V TTL and CMOS outputs while powered from a 3.3 V supply - a core feature of the LVT family that eliminates external level-shifting circuitry in mixed-voltage designs.
Does 74LVT32DB,118 support hot-swap operation?
Yes, 74LVT32DB,118 supports hot-swap operation due to its specified IOFF (output off current) of ±100 µA at VCC = 0 V. This ensures negligible backfeed current when the device is unpowered but connected to live buses - critical for modular backplane systems and field-replaceable units where cards may be inserted or removed under power.
What is the recommended decoupling for 74LVT32DB,118?
A 100 nF X7R ceramic capacitor placed within 3 mm of the 74LVT32DB,118 VCC (pin 14) and GND (pin 7) terminals is recommended. This minimizes high-frequency supply impedance and suppresses simultaneous switching noise - especially important given the device's 64 mA output drive and sub-4 ns propagation delays, which can induce significant transient currents.
Can 74LVT32DB,118 replace 74LVT32D in existing designs?
Yes, 74LVT32DB,118 is a direct functional and pin-compatible replacement for 74LVT32D, differing only in package: SO-14 (SOT108-1) vs. SSOP-14 (SOT337-1). Both share identical electrical specifications, timing, and thermal ratings. Layout adaptation is required only for the narrower 0.65 mm lead pitch and 5.3 mm body width of the SSOP variant.
What logic family does 74LVT32DB,118 belong to, and how does it differ from LVC?
74LVT32DB,118 belongs to the LVT (Low-Voltage TTL) family, distinguished by 5 V-tolerant inputs and higher drive strength (64 mA sink) versus LVC (Low-Voltage CMOS) variants like SN74LVC32APW. While both operate down to 1.65 V, only LVT guarantees safe 5 V input operation at 3.3 V VCC - making 74LVT32DB,118 uniquely suited for legacy system upgrades without redesigning signal conditioning.
