Product details

Overview

74LVC1G08QW5-7 from Diodes Incorporated is an automotive-grade single 2-input positive AND gate in SOT25 package, operating from 1.65V to 5.5V supply, with ±24mA output drive at 3.3V, 5.5V-tolerant inputs, and IOFF-enabled partial power-down protection. It performs Boolean Y = A • B and is used for voltage-level shifting and signal isolation in automotive control modules.

For engineers reviewing the 74LVC1G08QW5-7 datasheet, 74LVC1G08QW5-7 pinout, 74LVC1G08QW5-7 application, or 74LVC1G08QW5-7 equivalent, key selection criteria include Grade 1 temperature range (–40°C to +125°C), IOFF leakage < ±2 μA, propagation delay ≤6.0 ns at 3.3V, 5.5V input tolerance, and AEC-Q100 qualification for automotive systems.

Technical Context

This device implements a non-inverting 2-input AND logic function with push-pull CMOS output stage. Its IOFF circuit disables output during power-down to prevent back-current flow, enabling safe use in mixed-voltage, hot-swap, or partial-power-down systems.

Input thresholds are V_IH = 0.65×V_CC (1.65–1.95V), 1.7V (2.3–2.7V), 2.0V (3.0–3.6V), and 0.7×V_CC (4.5–5.5V); V_IL is correspondingly defined. Propagation delay ranges from 0.5 ns (typ) at 5.0V to 3.4 ns (typ) at 1.8V, supporting timing-critical logic interfacing across supply voltages.

Key Specifications

Pin/Terminal	Circuit Role	Design Meaning
1 (A)	Data Input	First logic input; accepts 5.5V-tolerant signals regardless of V_CC
2 (B)	Data Input	Second logic input; fully compatible with A for symmetric AND operation
3 (GND)	Ground Reference	Return path for supply and logic; must be low-impedance for noise immunity
4 (Y)	Data Output	Push-pull CMOS output; sinks or sources up to ±24 mA at 3.3V
5 (V_CC)	Supply Voltage	Primary power rail; powers internal logic and output stage; decoupling required

Key Features

Feature	Design Value

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	Same logic function and IOFF, but rated only to +85°C (commercial grade); no AEC-Q100 qualification	Not suitable for under-hood automotive use; limited to industrial or consumer PCBs	Select when cost is prioritized over automotive qualification and temperature range
74LVC1G08GW,125	Identical AEC-Q100 Grade 1 spec, but in SOT353 (2.15×2.1 mm) - smaller footprint, higher thermal resistance (θ_JA = 385°C/W)	Better space efficiency but reduced thermal performance in high-power-density layouts	Select when board area is constrained and thermal load is minimal

Compared with SN74LVC1G08DBVR and 74LVC1G08GW,125, the 74LVC1G08QW5-7 uniquely combines SOT25's thermal robustness (θ_JA = 184°C/W), full automotive qualification, and industry-standard 0.95 mm pitch for reliable reflow and test accessibility.

FAQ

What is the maximum allowable input voltage when V_CC = 0V?

The 74LVC1G08QW5-7 supports 5.5V-tolerant inputs regardless of V_CC state. When V_CC = 0V, the IOFF circuit isolates the output, and inputs remain safe up to 5.5V - verified per AEC-Q100 stress testing and absolute maximum ratings (VI = –0.5V to 6.5V).

Does this device require external pull-up or pull-down resistors on unused inputs?

Yes. Per datasheet Note 6, unused inputs must be tied to V_CC or GND to prevent floating states that cause increased ICC, noise susceptibility, or undefined output. No internal termination is provided; external biasing is mandatory for stable operation.

Can the 74LVC1G08QW5-7 drive a 50 pF load at 10 MHz while maintaining signal integrity?

Yes. With typical CPD = 16 pF and t_PD ≤6.0 ns at 3.3V, the device delivers clean edges into 50 pF loads at 10 MHz. Measurement data confirms VOL ≤0.80 V and VOH ≥2.0 V under 24 mA load, ensuring adequate noise margin in real-world routing scenarios.

Is the SOT25 package RoHS and halogen-free compliant?

Yes. The 74LVC1G08QW5-7 is fully RoHS 3 compliant (2015/863/EU) and halogen-free: Br < 900 ppm, Cl < 900 ppm (Br+Cl < 1500 ppm), Sb < 1000 ppm. This is certified in Diodes Incorporated's "Green" product definitions and verified via material declarations.
