Product details
Overview
74HCT2G08DC-Q100 from Nexperia is a dual 2-input AND gate IC with TTL-compatible inputs, operating from 4.5 V to 5.5 V supply, qualified to AEC-Q100 Grade 1 (−40 °C to +125 °C), and housed in a VSSOP8 (SOT765-1) package with 2.3 mm body width. It delivers propagation delay as low as 14 ns at VCC = 4.5 V and supports automotive body control modules requiring robust logic-level interfacing.
For engineers reviewing the 74HCT2G08DC-Q100 datasheet, 74HCT2G08DC-Q100 pinout, 74HCT2G08DC-Q100 application, or 74HCT2G08DC-Q100 equivalent, this page provides verified functional role, validated pin mapping, confirmed automotive-grade thermal and ESD specs, and real-world substitution guidance - all extracted from Nexperia's official Rev. 3 product data sheet (Nov 2023).
Technical Context
This device implements two independent AND logic gates in a single monolithic CMOS structure, with input clamp diodes enabling safe interface to voltages exceeding VCC when used with current-limiting resistors. Its TTL-level input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V) ensure compatibility with legacy 5 V microcontroller I/O and sensor outputs.
Designed for automotive environments, it meets AEC-Q100 Grade 1 requirements with guaranteed operation up to +125 °C ambient, latch-up immunity >100 mA per JESD78 Class II Level B, and ESD protection rated at HBM >2000 V and CDM >1000 V - critical for under-hood and infotainment subsystems exposed to electrical transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual independent 2-input AND gate - enables compact implementation of boolean conjunction in signal routing or enable control paths. |
| Supply Voltage Range | 4.5 V to 5.5 V - matches standard automotive 5 V rail tolerance and avoids level-shifting in 5 V systems. |
| Propagation Delay (tpd) | 14 ns typical (VCC = 4.5 V, CL = 15 pF) - supports timing-critical functions such as PWM synchronization or sensor data gating. |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - ensures reliable recognition of TTL-compatible signals without external biasing. |
| Operating Temperature | −40 °C to +125 °C - certified for engine bay, transmission control, and ADAS domain controller mounting locations. |
| ESD Protection | HBM >2000 V, CDM >1000 V - mitigates field failures during assembly and vehicle service handling. |
| Output Drive | ±4.0 mA at VCC = 4.5 V - sufficient to drive multiple CMOS inputs or small LED indicators directly. |
Pinout & Package
VSSOP8 plastic very thin shrink small outline package (SOT765-1); 8 leads; body width 2.3 mm; pin 1 indicator located below marking code in lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First gate input A - accepts TTL-level logic signal; clamp diode allows overvoltage tolerance with series resistor. |
| 2 | 1B | First gate input B - identical electrical behavior to Pin 1; dual-input AND requires both high for output assertion. |
| 3 | 1Y | First gate output Y - active-high AND result; drives downstream logic or pull-up/pull-down networks. |
| 4 | GND | Ground reference - must be low-impedance connection to minimize noise coupling into logic thresholds. |
| 5 | 2A | Second gate input A - electrically isolated from first gate; enables independent logic path within same footprint. |
| 6 | 2B | Second gate input B - shares same VIH/VIL specs as Pins 1/2; supports parallel signal conditioning. |
| 7 | 2Y | Second gate output Y - complements Pin 3; allows dual enable/control functions without extra ICs. |
| 8 | VCC | Positive supply - decoupling capacitor (100 nF ceramic) required within 5 mm for stable switching performance. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use across −40 °C to +125 °C ambient, including thermal cycling and humidity testing per JEDEC JESD22. |
| TTL-compatible input levels | VIH ≥ 2.0 V and VIL ≤ 0.8 V at 4.5–5.5 V supply - eliminates need for level translators when interfacing with 5 V MCUs or sensors. |
| Input clamp diodes | Enable safe interface to signals up to VCC + 0.5 V using external current-limiting resistors - protects against transient overvoltage in CAN/LIN bus nodes. |
| Low dynamic power dissipation | CPD = 10 pF - limits switching power to <1 mW at 1 MHz with 15 pF load, reducing thermal load in dense PCB layouts. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive parasitic thyristor activation during ESD or supply bounce events. |
Applications
| Body Control Module (BCM) | Infotainment System Power Sequencing |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 2-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT2G08DP-Q100 | Same logic function and AEC-Q100 Grade 1 rating, but in TSSOP8 (SOT505-2) package with 3.0 mm body width and 0.5 mm lead length. | Higher board space requirement and slightly higher thermal resistance (4.6 mW/K derating above 96 °C vs. 4.9 mW/K above 99 °C for DC). | Select when existing PCB layout uses TSSOP8 footprints or when manual soldering is preferred due to larger pad pitch. |
| SN74LVC2G08QDCURQ1 | TI part with LVCMOS inputs (VIH = 2.0 V min at VCC = 3.3 V), wider supply range (1.65–5.5 V), and faster tpd (1.7 ns typ at VCC = 3.3 V). | Not qualified to AEC-Q100 Grade 1; rated only to −40 °C to +125 °C with unspecified automotive test coverage. | Use only in non-safety-critical 3.3 V domains where AEC-Q100 compliance is not mandated, e.g., rear-seat entertainment subsystems. |
Compared with 74HCT2G08DP-Q100, the DC variant saves 0.7 mm in board width and improves thermal derating margin; versus SN74LVC2G08QDCURQ1, it trades raw speed for guaranteed automotive qualification, making it the sole choice for ASIL-B–related logic interlocks.

FAQ
Is 74HCT2G08DC-Q100 pin-compatible with 74HC2G08DC-Q100?
Yes - both share identical VSSOP8 (SOT765-1) pinout and terminal functions. However, 74HC2G08DC-Q100 uses CMOS-level inputs (VIH ≥ 3.15 V at VCC = 4.5 V), whereas 74HCT2G08DC-Q100 uses TTL-level inputs (VIH ≥ 2.0 V). Swapping them requires verifying source driver compatibility to avoid logic misreads.
What is the maximum capacitive load this device can drive reliably?
The datasheet specifies guaranteed timing performance up to 50 pF load capacitance (Table 10). At CL = 50 pF and VCC = 4.5 V, propagation delay remains ≤36 ns. Driving >50 pF may increase transition time and cause setup/hold violations in synchronous interfaces - add a buffer stage if required.
Does this device support mixed-voltage interfacing, e.g., 3.3 V inputs with 5 V supply?
No - input voltage ratings are referenced to GND and must stay within 0 V to VCC. With VCC = 4.5–5.5 V, applying 3.3 V inputs is safe (within VIH/VIL windows), but applying >5.5 V violates absolute maximum rating (VCC + 0.5 V limit). Clamp diodes only protect against brief transients, not sustained overvoltage.
How does the input clamp diode affect PCB layout for overvoltage protection?
The internal clamp diodes conduct when input voltage falls below GND −0.5 V or exceeds VCC + 0.5 V. To prevent damage, a series current-limiting resistor (e.g., 1 kΩ) must be placed between the external signal source and each input pin - limiting peak current to <20 mA per diode as specified in Table 5.
