Product details
Overview
74HCT1G08GW,165 from Nexperia is a single 2-input AND gate logic IC designed for level-translating digital signal conditioning in mixed-voltage systems. It features TTL-compatible inputs (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), operates from 4.5 V to 5.5 V, delivers ±2.0 mA output drive, and supports −40 °C to +125 °C industrial temperature range - used in power management sequencing, microcontroller I/O expansion, and sensor interface enable logic.
For engineers reviewing the 74HCT1G08GW,165 datasheet, 74HCT1G08GW,165 pinout, 74HCT1G08GW,165 application, or 74HCT1G08GW,165 equivalent, this device is selected for robust noise immunity (typ. 1.2 V noise margin), low static current (<20 μA at VCC = 5.5 V), precise propagation delay matching (tpd = 11–27 ns over temp), and compatibility with legacy 5 V TTL logic families while interfacing with modern 5 V CMOS controllers.
Technical Context
This device implements a single 2-input AND function using silicon-gate CMOS technology with TTL-level input thresholds, enabling direct connection to standard 5 V TTL outputs without level shifters. Its input clamp diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors.
The logic core is fully static, with symmetrical output impedance (typ. 25 Ω pull-up/pull-down), balanced tPLH/tPHL propagation delays (≤3 ns skew), and guaranteed latch-up immunity (>100 mA per JESD78 Class II Level B). It is not a programmable or configurable logic device - behavior is fixed per truth table: Y = A · B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 2-input AND gate (Y = A · B); no internal feedback or configuration registers. |
| Supply Voltage Range | 4.5 V to 5.5 V - optimized for stable 5 V rail operation; not rated below 4.5 V for HCT version. |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - ensures reliable recognition of standard TTL logic levels at VCC = 5 V. |
| Output Drive | ±2.0 mA at VCC = 4.5 V - sufficient to drive one 74-series TTL input or multiple CMOS loads (fan-out ≥ 10). |
| Propagation Delay | 11 ns (typ) to 27 ns (max) at CL = 50 pF, VCC = 4.5 V - enables timing-critical enable/enable-acknowledge paths up to ~30 MHz. |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive modules, industrial PLC I/O, and high-reliability embedded control. |
| ESD Protection | HBM >2000 V, CDM >1000 V - withstands handling and board-level ESD events without external protection. |
Pinout & Package
TSSOP5 (SOT353-1) package: plastic thin shrink small outline, 5-lead, body width 1.25 mm, 0.65 mm pitch, exposed padless, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B) | Data input | Standard CMOS input with clamp diodes; accepts TTL- or CMOS-level signals; must be terminated to avoid floating. |
| 2 (A) | Data input | Identical to Pin 1; both inputs are electrically symmetric and interchangeable in logic function. |
| 3 (GND) | Ground reference | Primary return path for all internal currents; requires low-impedance PCB connection to minimize ground bounce. |
| 4 (Y) | Data output | Push-pull CMOS output; drives HIGH to ≥4.13 V (at 2 mA sink), LOW to ≤0.33 V (at 2 mA source) at VCC = 4.5 V. |
| 5 (VCC) | Supply voltage | Power rail input; requires local 100 nF ceramic decoupling within 5 mm of pin for stable switching performance. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible input thresholds | Enables direct interface with legacy 5 V TTL outputs (e.g., 74LS, 74F) without level-shifting circuitry. |
| Symmetrical output impedance | Ensures matched rise/fall times (tPLH ≈ tPHL), reducing signal distortion in timing-sensitive enable paths. |
| Clamp diode-equipped inputs | Allows safe overvoltage tolerance (e.g., 12 V input via 10 kΩ resistor) without damaging the IC or requiring external diodes. |
| High noise immunity | Guaranteed 1.2 V DC noise margin at VCC = 5 V - suppresses coupling from adjacent switching traces or power rails. |
| Latch-up immunity >100 mA | Meets JESD78 Class II Level B - prevents destructive parasitic SCR activation during transient overcurrent events. |
Applications
| Power Sequencing Control | Microcontroller GPIO Expansion |
|---|---|
Use Scenario: Coordinating startup order of multiple DC-DC converters in FPGA or SoC power domains. IC Role / Device Role / Timing Role: AND gate enables downstream regulator only after both primary and auxiliary rails reach valid voltage. Use Value: Prevents backfeeding and inrush conflicts by enforcing strict logical dependency between power-good signals. |
Use Scenario: Extending limited GPIO count on an ARM Cortex-M0+ MCU to drive eight discrete LED indicators. IC Role / Device Role / Timing Role: Combines two MCU output pins to generate unique enable signals for LED driver ICs. Use Value: Reduces firmware complexity and eliminates need for software bit-banging by offloading combinatorial logic to hardware. |
| Sensor Interface Enable Logic | Industrial Serial Bus Isolation Control |
Use Scenario: Enabling analog sensor signal conditioning only when system is in active measurement mode. IC Role / Device Role / Timing Role: Gates sensor bias voltage and ADC clock enable based on master controller and sleep-wake status. Use Value: Cuts quiescent current by >95% during standby while preserving fast wake-up response (<100 ns latency). |
Use Scenario: Controlling isolated RS-485 transceiver direction and enable lines in a DIN-rail PLC module. IC Role / Device Role / Timing Role: Synchronizes DE/RE control signals to prevent bus contention during half-duplex transitions. Use Value: Eliminates metastability and bus glitches by ensuring strict AND-gated coordination of isolation-side control signals. |
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 | Wider supply range (1.65–5.5 V), CMOS inputs (VIH = 70% VCC), lower ICC (<10 μA), but no TTL input compatibility. | Preferred for battery-powered 3.3 V systems; unsuitable where legacy 5 V TTL drivers must be interfaced directly. | Select when operating below 4.5 V or when ultra-low static power dominates design priority. |
| 74AHC1G08GW,165 | CMOS input thresholds (VIH = 3.15 V min at VCC = 4.5 V), faster tpd (7 ns typ), identical TSSOP5 package and pinout. | Used where higher speed and rail-to-rail CMOS compatibility are required, but cannot accept standard TTL logic levels. | Select when interfacing exclusively with 5 V CMOS sources and sub-10 ns delay is critical. |
Compared with SN74LVC1G08DBVR and 74AHC1G08GW,165, the 74HCT1G08GW,165 uniquely bridges TTL and CMOS domains at 5 V while maintaining industrial temperature rating and proven latch-up robustness - making it the default choice for retrofitting legacy 5 V logic systems.

FAQ
Is 74HCT1G08GW,165 pin-compatible with 74HC1G08GW,165?
Yes - both share identical TSSOP5 (SOT353-1) pinout and footprint. However, 74HC1G08GW uses CMOS input thresholds (VIH = 3.15 V min at VCC = 4.5 V), while 74HCT1G08GW uses TTL thresholds (VIH = 2.0 V min). Swapping requires verification of driving source logic family compatibility.
Can 74HCT1G08GW,165 operate at 3.3 V supply?
No - the 74HCT variant is specified only from 4.5 V to 5.5 V. At 3.3 V, input thresholds become undefined and output drive degrades significantly. For 3.3 V systems, use 74LVC1G08 or 74AHC1G08 instead.
What is the maximum capacitive load this device can drive reliably?
It is characterized up to 50 pF (tpd tested at CL = 50 pF). Driving >100 pF may increase propagation delay nonlinearly and cause marginal timing in high-speed interfaces. For heavier loads, add a buffer stage or reduce trace length and capacitance.
Does this part support hot-swap or live-insertion?
No - it lacks powered-off protection or Ioff specification. Applying input signals while VCC = 0 V may forward-bias internal clamp diodes and cause excessive current flow. Always power VCC before applying inputs in hot-swap scenarios.
