Product details
Overview
74LVC1G08QSE-7 from Diodes Incorporated is an automotive-grade single 2-input positive AND gate in SOT353 package, operating from 1.65V to 5.5V with ±24mA output drive at 3.3V, 5.5V-tolerant inputs, and IOFF partial power-down protection. It performs Boolean Y = A · B and is qualified per AEC-Q100 Grade 1 (–40°C to +125°C) for use in vehicle body control modules.
For engineers reviewing the 74LVC1G08QSE-7 datasheet, 74LVC1G08QSE-7 pinout, 74LVC1G08QSE-7 application, or 74LVC1G08QSE-7 equivalent, key selection criteria include voltage-level translation capability across mixed-supply domains, low-power CMOS logic performance under automotive thermal stress, and IOFF-enabled signal isolation during system power sequencing.
Technical Context
This device implements a non-inverting 2-input AND function with push-pull output stage, supporting rail-to-rail input voltage range up to 5.5V independent of VCC. Its IOFF circuit actively disables output leakage when VCC = 0V, preventing back-current flow in partial-power-down systems.
Propagation delay is specified from 0.5ns (typ, 5V) to 3.4ns (typ, 1.8V); output drive strength scales with supply voltage - delivering –24mA/24mA at 3V and –32mA/32mA at 4.5V - while maintaining <100μA ICC at 5.5V and 25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G08DBVR | Non-automotive grade; rated –40°C to +85°C only; identical electrical specs and SOT23-5 package | Lacks AEC-Q100 qualification and IOFF characterization for automotive power sequencing | Select when cost-sensitive industrial or consumer designs do not require automotive qualification |
| 74LVC1G08GW,125 | NXP variant in SC-70 (SOT323) package; same Grade 1 temp rating but 0.6mm pitch vs. 0.65mm; slightly higher θJA (390°C/W) | Compatible footprint but requires requalification of solder joint reliability due to finer pitch | Choose for legacy NXP-sourced designs or where SC-70 placement equipment is already deployed |
Compared with SN74LVC1G08DBVR and 74LVC1G08GW,125, the 74LVC1G08QSE-7 uniquely combines AEC-Q100 Grade 1 qualification, verified IOFF behavior, and SOT353's optimized thermal resistance (θJA = 385°C/W), making it the only option qualified for safety-critical automotive power-gating functions.

FAQ
Is the 74LVC1G08QSE-7 pin-compatible with standard SOT23-5 logic gates?
No - the 74LVC1G08QSE-7 uses SOT353 (also known as SC-88A), which has 0.65mm lead pitch and different pin spacing than SOT23-5 (0.95mm pitch). Pin numbering matches (1=A, 2=B, 3=GND, 4=Y, 5=VCC), but mechanical layout requires dedicated footprint design and reflow profile validation.
Does the IOFF feature activate automatically when VCC drops below a threshold?
Yes - the IOFF circuit engages when VCC falls near 0V, disabling the output stage to prevent reverse current flow through the output clamp diodes. This behavior is characterized down to 0V VCC and is guaranteed across –40°C to +125°C per AEC-Q100 test requirements.
Can this AND gate operate reliably at 1.65V supply while driving a 30pF load?
Yes - propagation delay is specified at 10.5ns (max) and output drive remains functional at 1.65V, with VOL ≤0.70V and VOH ≥0.95V under 4mA load. The 30pF load is within tested conditions per the datasheet's switching characteristics measurement setup.
What is the maximum input transition rate supported without causing logic errors?
The device supports input rise/fall rates up to 20 ns/V at 1.8V, 10 ns/V at 3.3V, and 5 ns/V at 5.0V. Exceeding these rates may induce shoot-through current or metastability; external series resistors are recommended for >50MHz clock-derived inputs to limit di/dt.
