Product details
Overview
74AHCT1G08GW,125 from Nexperia is a single 2-input AND gate in TSSOP5 (SOT353-1) package, designed for level translation in mixed-voltage systems with TTL-compatible inputs, 4.5 V to 5.5 V supply operation, and overvoltage-tolerant inputs up to 5.5 V. It delivers symmetrical output drive (±8 mA), balanced propagation delays (3.6–8.0 ns at 5 V/50 pF), and operates across –40 °C to +125 °C for industrial control and sensor interface logic.
For engineers reviewing the 74AHCT1G08GW,125 datasheet, 74AHCT1G08GW,125 pinout, 74AHCT1G08GW,125 application, or 74AHCT1G08GW,125 equivalent, key selection criteria include TTL-level input compatibility, 5 V supply margin, overvoltage tolerance on inputs, thermal performance in TSSOP5, and propagation delay consistency across temperature.
Technical Context
This device implements standard positive-logic AND functionality with dual inputs (A, B) and one output (Y), where Y = A · B. Its TTL-compatible input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC = 4.5–5.5 V) enable direct interfacing with legacy 5 V TTL outputs without external biasing.
The IC features overvoltage-tolerant inputs rated to 5.5 V independent of VCC, allowing safe operation when driven by higher-voltage signals in voltage-translating configurations. Its CMOS output stage provides rail-to-rail swing, symmetrical impedance, and latch-up immunity exceeding 100 mA per JESD78 Class II Level A.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Applications
| Industrial Sensor Interface | PLC I/O Logic Conditioning |
|---|---|
|
Use Scenario: Combining two fault signals (e.g., overtemperature and overcurrent) before triggering shutdown in a motor drive controller. IC Role / Device Role / Timing Role: Single-gate logic combiner performing real-time safety interlock evaluation with sub-10 ns latency. Use Value: Eliminates need for larger logic arrays; compact TSSOP5 footprint saves PCB space in dense I/O modules. |
Use Scenario: Enabling analog input channel sampling only when both enable and ready signals are asserted in a programmable logic controller backplane. IC Role / Device Role / Timing Role: Synchronous gating element synchronizing data acquisition windows with system clock domain boundaries. Use Value: Provides deterministic setup/hold timing due to balanced propagation delays, reducing metastability risk. |
| Legacy System Voltage Translation | Embedded Microcontroller Peripheral Enable |
|
Use Scenario: Interfacing a 3.3 V microcontroller GPIO to a 5 V legacy display module requiring active-HIGH enable with TTL thresholds. IC Role / Device Role / Timing Role: Bidirectional voltage translator leveraging overvoltage-tolerant inputs and 5 V CMOS output swing. Use Value: Avoids dedicated level shifter ICs; single gate consumes <1 μA ICC at standby, preserving battery life. |
Use Scenario: Controlling power-enable to an RS-485 transceiver only when both MCU UART activity and bus idle status are confirmed. IC Role / Device Role / Timing Role: Dual-input enable gate ensuring transceiver activation aligns precisely with communication protocol state. Use Value: Prevents spurious bus contention via hardware-enforced sequencing, improving EMI compliance and data integrity. |
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 |
|---|---|---|---|
| 74AHCT1G08GV,125 | Same logic and specs, but in SC-74A (SOT753) package - slightly larger footprint, 0.95 mm pitch, no exposed pad | Preferred for manual assembly or reflow profiles incompatible with TSSOP5's fine pitch | Select when board assembly process lacks precision placement capability for 0.65 mm pitch devices |
| SN74LVC1G08DBVR | CMOS input thresholds (VIH = 70% VCC), 1.65–5.5 V supply, lower ICC (<10 μA), but no overvoltage tolerance beyond VCC | Suitable for single-supply 3.3 V systems; unsuitable for mixed-voltage translation without external clamping | Choose only for 3.3 V-only designs where input overvoltage risk is absent and ultra-low static current is critical |
Compared with 74AHCT1G08GW,125, the GV variant trades package density for assembly robustness, while the SN74LVC1G08DBVR sacrifices overvoltage tolerance and TTL compatibility for wider supply range and lower quiescent current - making the GW version uniquely suited for 5 V industrial translation tasks.

FAQ
Can 74AHCT1G08GW,125 operate reliably at 3.3 V supply?
No - the 74AHCT variant requires VCC ≥ 4.5 V to meet its specified TTL input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V). At 3.3 V, input recognition becomes unreliable. For 3.3 V systems, use the 74AHC1G08GW,125 variant instead, which has CMOS input thresholds referenced to VCC.
What is the maximum capacitive load this device can drive without exceeding propagation delay specs?
The datasheet specifies timing parameters up to CL = 50 pF. Driving >50 pF increases propagation delay nonlinearly and may cause marginal timing in high-speed paths. For loads >50 pF, add a buffer stage or verify timing margins using the measured tpd vs. CL curve in Section 11.
Does the overvoltage tolerance apply to the output pin (Y) as well?
No - overvoltage tolerance (up to 5.5 V) applies only to inputs A and B. The output Y is a standard CMOS push-pull stage referenced to VCC; applying voltage > VCC + 0.5 V or < –0.5 V violates absolute maximum ratings and risks permanent damage.
Is this device suitable for automotive applications?
No - the 74AHCT1G08GW,125 is not AEC-Q100 qualified. Nexperia explicitly states in its legal disclaimers that non-automotive-qualified products are unsuitable for safety-critical or automotive use. For automotive designs, select a Q100-qualified variant such as the 74AHCT1G08GW-Q100.
