Product details
Overview
74HCT1G08GV,125 from Nexperia is a single 2-input AND gate logic IC with TTL-compatible input thresholds, operating from 4.5 V to 5.5 V supply, featuring 11 ns typical propagation delay at 5 V/50 pF, ±2.0 mA output drive, and −40 °C to +125 °C temperature range - used for level-shifting, signal gating, and enable control in industrial microcontroller I/O expansion.
For engineers reviewing the 74HCT1G08GV,125 datasheet, 74HCT1G08GV,125 pinout, 74HCT1G08GV,125 application, or 74HCT1G08GV,125 equivalent, this device is selected for robust noise immunity, low static current (≤20 μA), symmetrical output impedance, and compatibility with legacy 5 V TTL logic families in space-constrained PCB layouts.
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-level input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC = 4.5–5.5 V) ensure reliable interfacing with 5 V microcontrollers and legacy peripherals without external level shifters.
It uses CMOS silicon technology with integrated input clamp diodes enabling safe interface to voltages exceeding VCC when current-limiting resistors are applied. Propagation delays are balanced (tPLH ≈ tPHL), and output drive capability supports fan-out of ≥10 LS-TTL loads under recommended conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 2-input AND gate (Y = A · B); enables conditional signal pass-through in digital control paths. |
| Supply Voltage Range | 4.5 V to 5.5 V - matches standard 5 V TTL and mixed-voltage system rails; not rated below 4.5 V. |
| Propagation Delay | 11 ns typical (VCC = 4.5 V, CL = 50 pF) - ensures timing predictability in high-speed enable/gating applications. |
| Output Drive | ±2.0 mA (VOH/VOL specified at IO = ±2.0 mA) - sufficient to drive multiple LS-TTL inputs or small capacitive loads. |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - guarantees interoperability with 5 V TTL outputs without level translation. |
| Operating Temperature | −40 °C to +125 °C - qualified for extended industrial and under-hood automotive-adjacent environments. |
| Static Supply Current | ≤20 μA max (VCC = 5.5 V, TA = −40 to +125 °C) - supports low-power always-on monitoring circuits. |
Pinout & Package
74HCT1G08GV,125 is housed in the SC-74A (SOT753) surface-mount package: plastic, 5-terminal, 1.3 mm × 1.7 mm body, 0.65 mm pitch, 0.95 mm height, with pin 1 index located below marking "T08" on lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B) | Data input | Second logic input; accepts TTL-level signals; clamped to GND/VCC via internal diodes. |
| 2 (A) | Data input | Primary logic input; electrically identical to Pin 1; supports same voltage and current limits. |
| 3 (GND) | Ground reference | 0 V return path for all internal circuitry and output current; must be low-impedance for noise immunity. |
| 4 (Y) | Data output | CMOS push-pull output; drives HIGH/LOW actively; capable of sourcing/sinking ±2.0 mA. |
| 5 (VCC) | Supply voltage | Positive rail connection; decoupling capacitor (100 nF) required within 5 mm for stable operation. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | VIH ≥ 2.0 V and VIL ≤ 0.8 V at 4.5–5.5 V - eliminates need for external level translators when interfacing with 5 V MCU GPIOs. |
| Symmetrical output impedance | Matched pull-up/pull-down strength ensures consistent rise/fall times and reduces signal distortion. |
| Input clamp diodes | Enable safe overvoltage tolerance (e.g., 12 V inputs) when series current-limiting resistors are used. |
| High noise immunity | Typical noise margin > 0.7 V (at VCC = 5 V) - suppresses false triggering in electrically noisy industrial enclosures. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up during transient overvoltage events. |
Applications
| Industrial PLC I/O Expansion | Microcontroller Peripheral Enable Control |
|---|---|
Use Scenario: Adding discrete enable logic to isolate sensor input banks in modular PLC backplanes. IC Role / Device Role / Timing Role: Gate for 5 V sensor data lines; synchronizes activation only when both master enable and channel select are asserted. Use Value: Prevents bus contention during hot-swap insertion by ensuring strict two-signal arbitration before signal routing. |
Use Scenario: Controlling power-on sequencing of SPI flash and UART transceivers in embedded edge nodes. IC Role / Device Role / Timing Role: Enables peripheral power domain only after MCU firmware confirms hardware readiness. Use Value: Eliminates startup glitches by enforcing deterministic power-enable dependency with sub-15 ns timing resolution. |
| Legacy System Bus Interface | Test Fixture Signal Conditioning |
Use Scenario: Adapting 5 V TTL address strobes from aging instrumentation controllers to modern FPGA-based data acquisition modules. IC Role / Device Role / Timing Role: Logic-level translator and signal combiner for address valid assertion across voltage domains. Use Value: Maintains setup/hold timing integrity while bridging mismatched logic families without added propagation skew. |
Use Scenario: Building reconfigurable test jigs that condition DUT trigger signals based on dual safety interlocks. IC Role / Device Role / Timing Role: Hardware-enforced AND gate verifying both operator confirmation and chamber door closure before test initiation. Use Value: Provides fail-safe, zero-software-dependency gating for functional safety-critical test sequences. |
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 |
|---|---|---|---|
| 74HCT1G08GW,125 | TSSOP5 (SOT353-1) package: 2.2 mm × 1.3 mm, 1.25 mm body width, 0.65 mm pitch - larger footprint but better thermal dissipation (Ptot derates at 3.3 mW/K above 74 °C). | Preferred for manual soldering or higher-power-density boards where thermal margin exceeds SC-74A limits. | Select when board assembly process favors TSSOP handling or when ambient temperature exceeds 105 °C regularly. |
| SN74LVC1G08DBVR | Wider VCC range (1.65–5.5 V), LVCMOS inputs, 3.7 ns typical tpd at 3.3 V/50 pF - faster but incompatible with pure 5 V TTL input thresholds. | Used in mixed-voltage 3.3 V/5 V systems requiring dynamic voltage scaling, not direct TTL replacement. | Choose only if migrating to 3.3 V core logic; avoid for legacy 5 V-only designs due to VIH mismatch (1.7 V min vs. required 2.0 V). |
Compared with 74HCT1G08GV,125, the GW variant offers superior thermal performance in high-ambient settings, while the SN74LVC1G08DBVR enables speed gains only in 3.3 V–compatible systems - neither provides drop-in replacement for 5 V TTL interfacing without redesign.

FAQ
Is 74HCT1G08GV,125 compatible with 3.3 V microcontroller outputs?
No - its TTL input thresholds require minimum 2.0 V for HIGH recognition, but 3.3 V MCU outputs typically meet this. However, VIH is only guaranteed at VCC ≥ 4.5 V; operation below 4.5 V is not specified. For true 3.3 V–native use, consider LVC-family equivalents instead.
Can this device drive an LED directly?
Not reliably - its absolute maximum output current is ±12.5 mA, but recommended continuous drive is ±2.0 mA per output. Driving even a low-current LED (e.g., 2 mA) risks violating VOL/VOH specs under load and degrades timing. Use a discrete transistor or buffer stage for LED loads.
What is the significance of the "T08" top-side marking?
"T08" is Nexperia's standardized marking code for 74HCT1G08GV devices in SC-74A packages. It uniquely identifies the logic function and technology variant, and is positioned adjacent to the pin 1 indicator (a small dot or bevel) on the lower-left corner of the package body.
Does this part support hot-swap or live-insertion?
It features input clamp diodes enabling safe overvoltage tolerance when used with series current-limiting resistors, but lacks dedicated hot-swap protection circuitry (e.g., slew-rate control or undervoltage lockout). Live insertion into powered backplanes requires external current limiting and sequencing design.
