产品概览
The M74VHC1GT125DT1G from onsemi is a single bus buffer/line driver with 3-state output in an ultra-compact SOT-353 package. 5V-tolerant inputs allow level translation from 5V to 3.3V domains. The active-low output enable provides tri-state for bus sharing.
主要规格
| 功能 | Single bus buffer with 3-state output |
| 电源电压 | 2.0V to 5.5V |
| 传播延迟 | 3.0 ns at 3.3V |
| Output Drive | ±8 mA at 3.3V |
| Input Tolerant | 5.5V |
| 包装 | SOT-353 (2.1×1.3mm) |
工作原理
When OE is LOW, the output follows the input (Y = A). When OE is HIGH, the output is in high-impedance (tri-state), allowing other devices to drive the bus. 5V-tolerant inputs accept signals above VCC, enabling mixed-voltage interfacing without damage.
应用
- Bus buffering with tri-state
- 5V to 3.3V level translation
- I/O port isolation
- Glue logic
