电平转换器-自动双向
GT0108
This 8-bit non-inverting translator which is a bidirectional voltage.level translator and can be used to build digital switchingcompatibility between multi voltage systems. This lC uses twoseparate configurable power supply tracks that including A portssupporting operating voltages from 1.65 V to 3.6 V with trackingVccA supply, and also including B ports supporting operatingvoltages from 2.3 V to 5.5 V with tracking Vcce supply.
The advantage above provides the support of both lower andhigher logic signal levels while providing bidirectional translationcapabilities between any of the 1.8-V,2.5-V, 3.3-V, and 5-Vvoltage circuit points.
Placing output-enable (OE)input to low level, all l/Os are forced tohigh-impedance state that significantly lower the quiescent currentconsumption.In order to ensure the high-impedance state duringpower up or power down, OE pin should be tied to GND via apulldown resistor, the minimum value of the resistor is determinedby the current-sourcing capability of the driver.
特性
- No direction-control
- Data rates
24 Mbps (Push Pull)
2 Mbps (Open Drain)
- 1.65 V to 3.6 V on A port and 2.3 V to 5.5 V on B
port (VCCA ≤ VCCB)
- VCC isolation feature: If either VCC input is at GND,
both ports are in the high-impedance state
- No power-supply sequencing required:
either VCCA or VCCB can be ramped first
- Ioff supports partial-power-down mode operation
- Operating temperature range:-40℃ to +85℃
