Product details
Overview
74LVT08D,112 from Nexperia is a 3.3 V quad 2-input AND gate in SO14 package, featuring IOFF partial power-down protection, ±32 mA/±64 mA output drive, 5.5 V-tolerant inputs, and operation from -40 °C to +85 °C. It serves as a level-shifting logic buffer in mixed-voltage digital control planes, such as FPGA I/O expansion and microcontroller peripheral interfacing.
For engineers reviewing the 74LVT08D,112 datasheet, 74LVT08D,112 pinout, 74LVT08D,112 application, or 74LVT08D,112 equivalent, key selection criteria include its BiCMOS output drive strength, 5.5 V input overvoltage tolerance, IOFF-enabled bus isolation during partial power-down, and guaranteed timing performance at 3.3 V across industrial temperature range.
Technical Context
The 74LVT08D implements four independent AND gates using BiCMOS technology, enabling high-speed switching (typ. 3.0 ns tPLH at 3.3 V) with TTL-compatible input thresholds and rail-to-rail output swing. Its IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current into powered-down sections of the system.
Inputs tolerate up to 5.5 V regardless of VCC state, allowing safe interfacing with 5 V buses without external level shifters. The device complies with JEDEC JESD8C (2.7–3.6 V), supports power-up 3-state, and meets JESD78 Class II Level B latch-up immunity (>500 mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7 V to 3.6 V - Ensures stable operation across 3.3 V nominal systems with ±0.3 V tolerance |
| Input Voltage Range | 0 V to 5.5 V - Enables direct connection to 5 V logic without clamping diodes or resistors |
| Output Drive (LOW) | 32 mA sink - Drives heavy capacitive loads or multiple CMOS/TTL inputs simultaneously |
| Output Drive (HIGH) | −32 mA source - Sustains clean HIGH-level signaling under load without droop |
| Propagation Delay | 3.0 ns typ. (tPLH), 3.4 ns typ. (tPHL) at VCC = 3.3 V - Supports >200 MHz toggle rates in critical paths |
| IOFF Leakage | ±100 μA max at VCC = 0 V - Prevents bus contention and power loss during partial shutdown |
| Operating Temperature | −40 °C to +85 °C - Qualified for industrial-grade embedded control and communications equipment |
Pinout & Package
74LVT08D,112 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; pin 1 index located at top-left corner when viewed from top with marking side up.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | 1A, 2A, 3A, 4A | First input per gate - Accepts 5.5 V-tolerant logic signals; no external pull-up required |
| 2, 5, 10, 13 | 1B, 2B, 3B, 4B | Second input per gate - Fully symmetrical with A inputs; enables flexible signal routing |
| 3, 6, 8, 11 | 1Y, 2Y, 3Y, 4Y | AND output per gate - Delivers rail-swing CMOS output with ±32 mA drive capability |
| 7 | GND | Ground reference - Must be low-impedance connection to minimize ground bounce in high-speed switching |
| 14 | VCC | Supply voltage - Powers internal BiCMOS circuitry; requires local 100 nF decoupling near pin |
Key Features
| Feature | Design Value |
|---|---|
| IOFF Partial Power-Down | Disables outputs at VCC = 0 V to prevent backfeed current into unpowered subsystems |
| 5.5 V Input Tolerance | Accepts 5 V logic levels while operating at 3.3 V supply - eliminates external level translators |
| BiCMOS Output Stage | Combines bipolar speed and CMOS low static power - achieves 3 ns propagation delay with <2 mA ICC |
| Power-Up 3-State | Outputs remain high-impedance until VCC stabilizes - prevents bus contention during power sequencing |
| Industrial Temp Range | Guaranteed functionality from −40 °C to +85 °C - suitable for factory automation and outdoor edge nodes |
Applications
| Industrial PLC I/O Expansion | FPGA Configuration Bus Control |
|---|---|
Use Scenario: Isolating and gating discrete sensor inputs (e.g., limit switches, photoelectric sensors) before feeding into a PLC CPU module. IC Role / Device Role / Timing Role: Logic-level AND gate performing signal validation and enable gating prior to CPU sampling. Use Value: IOFF prevents backfeed from powered PLC bus into unpowered sensor modules during maintenance; 5.5 V input tolerance accepts legacy 5 V sensor outputs directly. |
Use Scenario: Enabling configuration data strobes between FPGA and external SPI flash or configuration PROM during power-up sequence. IC Role / Device Role / Timing Role: Synchronizing and qualifying configuration clock enables to ensure reliable bitstream loading. Use Value: Sub-4 ns propagation delay ensures setup/hold timing margins are met; power-up 3-state avoids spurious writes during FPGA initialization. |
| Microcontroller Peripheral Interface | Backplane Signal Conditioning |
Use Scenario: Multiplexing GPIO-controlled status LEDs or relay drivers across shared MCU pins using enable logic. IC Role / Device Role / Timing Role: Gate-level enable controller translating MCU GPIO states into parallel peripheral activation signals. Use Value: ±32 mA output drive directly drives LEDs or small-signal relays without external transistors; 3.3 V compatibility matches modern MCU I/O voltages. |
Use Scenario: Buffering and isolating control signals routed across a multi-slot industrial backplane with mixed 3.3 V/5 V domains. IC Role / Device Role / Timing Role: Bidirectional voltage-domain translator and noise-rejecting signal conditioner for backplane command lines. Use Value: 5.5 V input tolerance allows reception from 5 V master cards; IOFF blocks reverse current if slave slots lose power mid-operation. |
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), no IOFF, 1.65–3.6 V supply | Lacks partial power-down protection; unsuitable for hot-swap or mixed-power-domain isolation | Select only when IOFF is not required and cost sensitivity outweighs robustness needs |
| 74ALVC08D,112 | Same SO14 package, identical pinout, but no IOFF and lower ESD rating (HBM 2 kV vs. 2 kV, CDM C2 vs. C3) | Not rated for bus isolation during partial power-down; reduced latch-up immunity (JESD78 Class II Level A) | Use only in non-critical, single-rail 3.3 V systems where full IOFF functionality is unnecessary |
Compared with SN74LVC08APWR and 74ALVC08D,112, the 74LVT08D,112 uniquely delivers IOFF-enabled bus isolation, higher output drive, and stronger latch-up immunity-making it the only choice for industrial backplane and hot-pluggable I/O applications requiring fail-safe power sequencing.

FAQ
Does 74LVT08D,112 support true 5 V input logic levels while operating at 3.3 V?
Yes. Its inputs are overvoltage tolerant up to 5.5 V regardless of VCC state, enabling direct interface with 5 V TTL or CMOS outputs without level-shifting components. This is verified in Table 4 (Limiting Values) and Table 5 (Operating Conditions) of the official Nexperia datasheet Rev. 5.
What is the maximum capacitive load this device can drive while maintaining specified propagation delay?
The datasheet specifies dynamic characteristics with a 50 pF load (Table 9). At that load and VCC = 3.3 V, typical tPLH/tPHL remain ≤3.4 ns. Driving >50 pF increases delay nonlinearly; for >100 pF, derating or buffering is recommended to maintain timing integrity.
Can 74LVT08D,112 be used in hot-swap applications where VCC may be removed while other system rails remain active?
Yes. Its IOFF circuitry disables all outputs when VCC = 0 V, limiting backflow current to ±100 μA (Table 6). This prevents damage or corruption on live 5 V buses-a key feature validated per JESD78 Class II Level B latch-up testing.
Is the SO14 package (SOT108-1) RoHS compliant and lead-free?
Yes. Nexperia confirms the 74LVT08D,112 in SOT108-1 packaging meets RoHS Directive 2011/65/EU and is lead-free, with matte tin (Sn) termination finish. Full compliance documentation is available via Nexperia's product change notices and material declarations portal.
