Nexperia USA Inc. 74HCT1G08GV-Q100,1

Overview

74HCT1G08GV-Q100 from Nexperia is a single 2-input AND gate optimized for automotive applications, featuring TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), operation from −40 °C to +125 °C, and supply voltage range of 4.5 V to 5.5 V. It delivers balanced propagation delays (tpd = 11 ns typ at VCC = 4.5 V, CL = 50 pF) and low static current (ICC ≤ 20 μA max), enabling reliable logic-level translation in engine control units and body electronics.

For engineers reviewing the 74HCT1G08GV-Q100 datasheet, 74HCT1G08GV-Q100 pinout, 74HCT1G08GV-Q100 application, or 74HCT1G08GV-Q100 equivalent, this device serves as a qualified AEC-Q100 Grade 1 logic gate with SC-74A (SOT753) packaging, precise input/output voltage thresholds, and verified dynamic timing under automotive temperature extremes.

Technical Context

This device implements standard positive-logic AND functionality with symmetrical output impedance and balanced tPLH/tPHL propagation delays. Its TTL-level inputs interface directly with legacy 5 V microcontrollers and sensors without level-shifting circuitry.

Clamp diodes on all inputs allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors. The design meets JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V) standards and supports HBM ESD robustness >2000 V and CDM >1000 V.

FAQ

What is the maximum allowable input voltage when VCC = 5.0 V?

The absolute maximum input voltage is VCC + 0.5 V = 5.5 V, per Table 5 limiting values. Inputs include clamp diodes, so voltages up to 5.5 V are permissible only if input current remains within ±20 mA - achieved using external series resistors when interfacing to higher-voltage sources.

Does 74HCT1G08GV-Q100 support mixed-voltage interfacing (e.g., 3.3 V MCU driving its inputs)?

No - this is a TTL-input device requiring VIH ≥ 2.0 V and VIL ≤ 0.8 V at VCC = 4.5–5.5 V. A 3.3 V MCU output may not reliably meet VIH under worst-case conditions; level-shifting or use of the 74HC1G08GV-Q100 variant (CMOS input) is recommended for 3.3 V systems.

How does the SC-74A (SOT753) package affect thermal performance compared to TSSOP5?

The SC-74A package has a thermal derating slope of 3.8 mW/K above 85 °C (Table 5), versus 3.3 mW/K for TSSOP5 above 74 °C. While SOT753 offers smaller footprint, TSSOP5 provides better heat dissipation in sustained high-temperature operation due to larger copper exposure and leadframe geometry.

Is the 74HCT1G08GV-Q100 pin-compatible with non-automotive 74HCT1G08 variants?

Yes - pinout and electrical behavior match industry-standard 74HCT1G08 devices in SC-74A packaging. However, only the -Q100 suffix denotes AEC-Q100 Grade 1 qualification, including extended temperature testing, enhanced ESD robustness, and automotive-specific reliability screening not present in commercial-grade versions.
