- Bi-directional voltage translation with no direction pin
- One pass transistor per channel plus reference channels
- Level translation is achieved by a pass transistor and external pull-up resistors
- Intended for push-pull and open-drain interfaces (I2C)
Key features and benefits
- Complete Family – comprising of 1, 2, 4 and 8-channel level translators
- Easy to Use – Dual supply translating transceiver family
- Bi-directional auto-sensing voltage translation – no direction pin required
- Dual wide voltage supply range from 0.95 V to 5.0 V
- High speed Up translation
- ≤ 100 MHz; CL = 30 pF
- ≤ 40 MHz; CL = 50 pF
- High speed Down translation
- ≥ 100 MHz; CL = 30 pF
- ≤ 40 MHz; CL = 50 pF
- Support hot insertion
- Low RON provides less signal distortion
- Low standby current
- 5 V tolerant I/O pins to support TTL
- High-impedance I/O pins for EN = Low
- Flow-through pinout for easy PCB trace routing
- Multiple pin-compatible package options
- Specified from -40 °C to +125 °C
