LSF0108-Q1 Automotive 8-Channel Multi-Voltage Level Translator

1 Features

•AEC-Q100 qualified with the following results:

–Device HBM ESD classification level 2000-V

–Device CDM ESD classification level 1000-V

•Available in wettable flank VQFN (RKS) package

•Provides bidirectional voltage translation with no

direction pin

•Supports up to 100 MHz up translation and

greater than 100 MHz down translation at ≤ 30-pF

capacitive load and up to 40 MHz up or down

translation at 50-pF capacitive load

•Supports hot insertion

•Allow bidirectional voltage level translation

between

–0.65 V ↔ 1.8 V, 2.5 V, 3.3 V, 5 V (RKS package

only)

–0.95 V ↔ 1.8 V, 2.5 V, 3.3 V, 5 V

–1.2 V ↔ 1.8 V, 2.5 V, 3.3 V, 5 V

–1.8 V ↔ 2.5 V, 3.3 V, 5 V

–2.5 V ↔ 3.3 V, 5 V

–3.3 V ↔ 5 V

•Low standby current

•5-V tolerance I/O port to support TTL

•Low r

on

provides less signal distortion

•High-impedance I/O pins for EN = low

•Flow-through pin-out for easy PCB trace routing

•Latch-up performance exceeds 100 mA per JESD

17

•–40°C to +125°C operating temperature range

Functional Block Diagram

2 Applications

•GPIO, MDIO, PMBus, SMBus, SDIO, UART, I

2

C,

and other interfaces in telecom infrastructure

•Infotainment and cluster

•Body electronics and lighting

•Hybrid, electric, and powertrain systems

•Passive safety

•ADAS

3 Description

•Supports up to 100 MHz up translation and greater

than 100 MHz down translation at ≦ 30 pF

capacitive load and up to 40 MHz up and down

translation at 50 pF capacitive load:

–Allows the LSF family to support more

consumer or telecom interfaces (MDIO or

SDIO)

•Bidirectional voltage translation without DIR pin:

–Minimizes system effort to develop voltage

translation for bidirectional interface (PMBus,

I

2

C, or SMbus)

•5 V tolerance on IO port and 125°C support:

–With 5 V tolerance and 125°C support, the LSF

family is flexible and compliant with TTL levels

in industrial and telecom applications

•Channel specific translation:

–The LSF family is able to set up different

voltage translation levels on each channel
