Key Features
- Dual-supply transceiver with tri-state outputs, allowing for universal low-voltage translation between any voltages from 1.65V to 5.5V.
- Fully specified for partial power-down applications using IOFF, preventing damaging backflow current when powered down.
- The Direction pin (DIR) controls the direction of the transceiver, with the A pin becoming an input and the B pin becoming the output when DIR is high, and vice versa when DIR is low.
- Tri-state feature allows the output to remain in a high impedance state when either of the power supply voltages are zero.
- ROHS3 compliant.
Applications
The 74LVC1T45GW,125 is suitable for a variety of applications requiring voltage level translation, such as:
- Interface between different voltage domains in mixed-signal designs.
- Level shifting in digital circuits.
- Power management systems where partial power-down is necessary.
- Embedded systems and microcontrollers requiring flexible voltage translation.
Q & A
- What is the primary function of the 74LVC1T45GW,125?
The primary function is to act as a single-bit, dual-supply transceiver with tri-state outputs for transmitting a single logic bit across different voltage domains.
- What is the voltage range for VCCA and VCCB?
The voltage range for both VCCA and VCCB is from 1.2V to 5.5V.
- What package styles are available for this component?
The component is available in SC-88 (SOT-363, 6-TSSOP) package.
- What is the operating temperature range for this device?
The operating temperature range is from -40°C to 125°C.
- What is the data rate of the 74LVC1T45GW,125?
The data rate is up to 420Mbps.
