Product details
Overview
74LVT08DB,118 from Nexperia is a 3.3 V quad 2-input AND gate in SO14 (SOT108-1) package, featuring IOFF partial power-down protection, ±32 mA/±64 mA output drive, and 5.5 V-tolerant inputs. It operates across -40 °C to +85 °C and enables logic-level translation between 3.3 V LVTTL and 5 V TTL buses in industrial control backplanes.
For engineers reviewing the 74LVT08DB,118 datasheet, 74LVT08DB,118 pinout, 74LVT08DB,118 application, or 74LVT08DB,118 equivalent, this device supports high-speed bus interfacing with sub-4 ns propagation delay, robust ESD immunity (HBM >2000 V), and latch-up resistance exceeding 500 mA - critical for mixed-voltage system integration and hot-swap I/O staging.
Technical Context
The 74LVT08DB,118 implements four independent AND gates using BiCMOS technology to combine bipolar speed with CMOS low-power characteristics. Its IOFF circuit actively disables outputs during VCC = 0 V, blocking backflow current when powered down while inputs remain at 5.5 V.
It supports direct TTL-level interfacing without level shifters due to 5.5 V overvoltage-tolerant inputs and rail-to-rail output swing under 3.3 V supply. Propagation delays are specified at 3.0–3.6 V with tPLH/tPHL ≤ 3.9 ns and ≤ 4.6 ns respectively, enabling reliable operation up to 10 MHz clocked logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7 V to 3.6 V - ensures compatibility with 3.3 V LVTTL systems and tolerance to board-level rail variation. |
| Input Voltage Range | 0 V to 5.5 V - allows safe connection to 5 V TTL buses without external clamping or level shifting. |
| Output Drive | +64 mA sink / -32 mA source - drives heavy capacitive loads (e.g., 50 pF traces) and multiple TTL inputs simultaneously. |
| Propagation Delay | 3.0 ns typical (VCC = 3.3 V) - supports timing-critical combinational logic in data-path gating and address decoding. |
| IOFF Leakage | ±100 μA max at VCC = 0 V - prevents damaging back-current during partial power-down in modular systems. |
| Operating Temperature | -40 °C to +85 °C - qualified for industrial ambient environments including factory automation and telecom infrastructure. |
| ESD Rating | HBM >2000 V, CDM >1000 V - withstands handling and board assembly without special ESD controls. |
Pinout & Package
74LVT08DB,118 is housed in a plastic small outline package (SO14), SOT108-1, with 14 leads and 3.9 mm body width. Pin 1 is marked by a notch or bevel; the package is lead-free and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | 1A, 2A, 3A, 4A | First input per gate - accepts 0–5.5 V signals; internally clamped to protect core logic. |
| 2, 5, 10, 13 | 1B, 2B, 3B, 4B | Second input per gate - dual-input AND function requires both A and B HIGH for Y HIGH. |
| 3, 6, 8, 11 | 1Y, 2Y, 3Y, 4Y | Active-HIGH AND output - drives downstream logic or bus lines with full 3.3 V swing and high current capability. |
| 7 | GND | Ground reference - must be connected to system 0 V plane; decoupling capacitor recommended near pin. |
| 14 | VCC | 3.3 V supply input - requires local 100 nF ceramic decoupling; IOFF active when VCC = 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| IOFF Partial Power-down | Disables outputs at VCC = 0 V to prevent back-current into powered sections - essential for hot-plug I/O modules. |
| 5.5 V Input Tolerance | Accepts 5 V TTL signals directly without level shifters or resistive dividers - simplifies mixed-voltage board design. |
| BiCMOS Output Stage | Delivers +64 mA sink and -32 mA source - drives 10+ TTL loads or long PCB traces with minimal rise/fall time degradation. |
| Power-up 3-State | Outputs remain high-impedance until VCC stabilizes - eliminates bus contention during power sequencing. |
| Latch-up Immunity | Exceeds 500 mA per JESD78 Class II Level B - ensures robustness against transient ground bounce or supply glitches. |
Applications
| Industrial PLC Backplane Interface | Telecom Line Card Bus Gating |
|---|---|
|
Use Scenario: Isolating control signals between 3.3 V FPGA I/O banks and legacy 5 V peripheral modules on a shared backplane. IC Role / Device Role / Timing Role: Quad AND gate performing enable gating for address/data strobes with simultaneous 3.3 V/5 V voltage domain bridging. Use Value: Eliminates need for discrete level translators; IOFF prevents backfeed during module hot-swap, preserving system uptime. |
Use Scenario: Enabling/disabling signal paths between DSP cores and analog front-end ASICs on a line card with staggered power-up. IC Role / Device Role / Timing Role: Synchronous gating element for clock-enable and reset distribution with sub-4 ns delay matching. Use Value: Power-up 3-state avoids metastability on reset assertion; BiCMOS drive strength maintains signal integrity across 10 cm FR4 traces. |
| Automated Test Equipment (ATE) Signal Conditioning | Medical Imaging Data Path Control |
|
Use Scenario: Combining test pattern triggers and channel select bits before routing to high-density probe drivers. IC Role / Device Role / Timing Role: Combinational logic gate for real-time pattern masking and channel enable generation. Use Value: 5.5 V input tolerance accommodates legacy TTL pattern generators; low propagation skew (<0.5 ns) ensures deterministic timing alignment. |
Use Scenario: Gating X-ray detector pixel readout signals prior to ADC sampling in a radiation-hardened imaging subsystem. IC Role / Device Role / Timing Role: Critical path AND gate synchronizing pixel enable pulses with global frame clocks. Use Value: -40 °C to +85 °C rating supports fanless enclosure operation; latch-up immunity prevents single-event functional interrupts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC08APWR | Lower drive (+24 mA/–24 mA); no IOFF; 1.65–3.6 V supply range. | Lacks partial power-down protection; unsuitable for hot-swap or mixed-rail isolation. | Select only if IOFF is unnecessary and lower power consumption is prioritized over bus drive strength. |
| 74ALVC08D,118 | Same SO14 package; identical IOFF and 5.5 V input tolerance; slightly higher tPLH (4.2 ns typ). | Functionally interchangeable but marginally slower; same thermal and ESD specs. | Valid drop-in alternative where minor timing margin exists; verify setup/hold in critical paths. |
Compared with SN74LVC08APWR, the 74LVT08DB,118 provides superior bus drive and essential IOFF protection; versus 74ALVC08D,118, it delivers faster propagation (3.0 ns vs 4.2 ns) with identical packaging and interface robustness.

FAQ
Can 74LVT08DB,118 be used with a 5 V supply?
No. The absolute maximum VCC is +4.6 V, and recommended operation is strictly 2.7 V to 3.6 V. Applying 5 V to VCC will exceed limiting values and cause permanent damage. However, inputs tolerate up to 5.5 V while VCC is at 3.3 V - enabling safe interfacing with 5 V signal sources.
Does 74LVT08DB,118 support hot-swap insertion?
Yes - its IOFF circuitry disables all outputs when VCC = 0 V, preventing back-current flow from live 5 V buses into the unpowered IC. This meets IEC 61000-4-2 ESD and hot-swap safety requirements for modular chassis systems.
What is the maximum capacitive load this device can drive reliably?
At VCC = 3.3 V and Tamb = 25 °C, the device drives 50 pF loads with tPLH/tPHL ≤ 3.9 ns and maintains VOL ≤ 0.5 V at IOL = 32 mA. For heavier loads (>75 pF), derating of timing margins and verification of signal integrity via IBIS simulation is required.
Is there a pin-compatible TSSOP version of this part?
Yes - the 74LVT08PW (SOT402-1, TSSOP14) shares identical logic function, pinout, electrical specs, and IOFF behavior. It differs only in package dimensions and thermal resistance (RθJA = 137 K/W vs 105 K/W for SO14), requiring layout adjustment but no schematic change.
