Nexperia USA Inc. 74HC2G08DP-Q100/AH

Overview

74HC2G08DP-Q100 from Nexperia is a dual 2-input AND gate IC qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C with supply voltage range 2.0 V to 6.0 V, CMOS-level inputs, and propagation delay as low as 8 ns at VCC = 6.0 V - deployed in body control modules for logic-level signal coordination.

For engineers reviewing the 74HC2G08DP-Q100 datasheet, 74HC2G08DP-Q100 pinout, 74HC2G08DP-Q100 application, or 74HC2G08DP-Q100 equivalent, key selection factors include its automotive qualification, dual-gate integration in TSSOP8, input clamp diode support for overvoltage-tolerant interfacing, and guaranteed static/dynamic performance across extended temperature.

Technical Context

This device implements two independent AND logic functions in a single monolithic CMOS structure, with inputs featuring integrated clamp diodes enabling safe interface to signals exceeding VCC when used with current-limiting resistors. Each gate exhibits identical truth table behavior: output HIGH only when both inputs are HIGH.

It supports dual-voltage system interoperability: 74HC variant accepts CMOS-level inputs (VIH ≥ 70% VCC), while the pin-compatible 74HCT variant accepts TTL-level inputs (VIH = 2.0 V min at VCC = 4.5–5.5 V). Both share identical output drive capability (±4.0 mA at VCC = 4.5 V) and latch-up immunity (>100 mA per JESD78 Class II Level B).

FAQ

What is the maximum allowable supply voltage for 74HC2G08DP-Q100?

The absolute maximum supply voltage is +7.0 V, but the recommended operating range is 2.0 V to 6.0 V per the datasheet. Operation above 6.0 V voids guaranteed performance and risks permanent damage, even with brief exposure. Designers must implement supply rail clamping or regulation to stay within the 6.0 V upper limit for reliable long-term function.

Does 74HC2G08DP-Q100 support mixed-voltage interfacing?

Yes - integrated input clamp diodes allow safe interface to signals exceeding VCC when used with appropriate current-limiting resistors. For example, a 5.0 V signal can drive an input referenced to a 3.3 V VCC, provided the series resistor limits current to ≤20 mA. This eliminates need for external level translators in many automotive signal conditioning paths.

How does the 74HC2G08DP-Q100 differ from the 74HCT2G08DP-Q100 variant?

The core difference is input voltage thresholds: 74HC2G08DP-Q100 requires CMOS-level inputs (VIH ≥ 70% VCC), while 74HCT2G08DP-Q100 accepts TTL-level inputs (VIH = 2.0 V min at VCC = 4.5–5.5 V). All other parameters - pinout, timing, drive strength, package, and AEC-Q100 qualification - are identical. Selection depends solely on source logic family voltage levels.

Is thermal derating required for continuous operation at +125 °C?

Yes - for the TSSOP8 (SOT505-2) package, total power dissipation derates linearly at 4.6 mW/K above +96 °C. At +125 °C, maximum allowed PD drops to ~125 mW from the 250 mW rated value. Designers must calculate worst-case dynamic power (using CPD = 10 pF, toggle rate, and load capacitance) and verify junction temperature remains below 150 °C with board-level thermal design.
