3 Description

The LSF0102-Q1 device is an auto bidirectional

voltage translator that translates among a wide range

of supplies without the need for a directional pin. The

LSF0102-Q1 supports up to 100 MHz up translation

and greater than 100 MHz down translation with

capacitive loads

≤ 30 pF. Additionally, the LSF0102-

Q1 supports up to 40 MHz up and down translation at

50 pF capacitance load, which enables the LSF0102-

Q1 device to support a wide variety of standard

interfaces commonly found in automotive applications

The LSF0102-Q1 device has 5-V tolerant data inputs.

This makes the device compatible with TTL voltage

levels.

Furthermore,

the

LSF0102-Q1

supports

mixed-mode voltage translation, allowing the device

to up translate and down translate to different supply

levels on each channel.
