Product Overview
The 74AHCT1G08GV,125 from Nexperia is a single 2-input AND gate with TTL-compatible inputs in an ultra-compact SOT-353 package. It operates from 4.5V to 5.5V with TTL input thresholds, enabling direct interface from 3.3V logic to 5V TTL systems.
Key Specifications
| Function | Single 2-input AND gate |
| Supply Voltage | 4.5V to 5.5V |
| Input Logic | TTL compatible |
| Propagation Delay | 4.5 ns at 5V |
| Output Drive | ±8 mA at 5V |
| Package | SOT-353 (2.1×1.3mm) |
Working Principle
CMOS AND gate: Y = A AND B. Output is HIGH only when both inputs are HIGH. The AHCT variant has TTL-compatible input thresholds (VIH=2V) allowing 3.3V logic to drive inputs while powered at 5V. TinyLogic single-gate footprint saves board space versus a quad-gate package.
Applications
- 3.3V to 5V enable qualification
- Signal gating / masking
- Address decode
- Control qualification
