Q & A
- What is the primary function of the 74CBTLV3257PW-Q1AJ?
The primary function is to act as a quad 1-of-2 high-speed multiplexer/demultiplexer with common select and output enable inputs.
- What is the operating voltage range of the 74CBTLV3257PW-Q1AJ?
The operating voltage range is from 2.3 V to 3.6 V.
- What is the ON resistance of the switch in the 74CBTLV3257PW-Q1AJ?
The ON resistance of the switch is 7 Ω.
- What type of ESD protection does the 74CBTLV3257PW-Q1AJ offer?
The device offers ESD protection exceeding 2000 V for HBM and 1000 V for CDM.
- What is the maximum operating temperature of the 74CBTLV3257PW-Q1AJ?
The maximum operating temperature is +125 °C.
- What package options are available for the 74CBTLV3257?
The device is available in TSSOP16 (SOT403-1) and other package options like DHVQFN16 (SOT763-1).
- What are the typical applications of the 74CBTLV3257PW-Q1AJ?
Typical applications include IoT devices, wireless headphones, television sets, and automotive and industrial systems.
- How does the output enable (OE) input affect the switches in the 74CBTLV3257PW-Q1AJ?
When the OE input is LOW, one of the two switches is selected (low-impedance ON-state) with the select (S) input. When the OE input is HIGH, all switches are in the high-impedance OFF-state, independent of the S input.
- What is the significance of the Ioff feature in the 74CBTLV3257PW-Q1AJ?
The Ioff feature supports partial-power-down mode operation, ensuring that damaging current will not backflow through the device when it is powered down.
- How does the device handle power-up and power-down states?
To ensure a high-impedance state during power up or power down, the OE input should be tied to VCC through a pullup resistor.
