LSF0101 1-Channel Auto-Bidirectional Multi-Voltage Level Translator
for Open-Drain and Push-Pull Applications
1 Features
•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
•Allows bidirectional voltage-level translation
between
–0.95 V ↔ 1.8/2.5/3.3/5 V
–1.2 V ↔ 1.8/2.5/3.3/5 V
–1.8 V ↔ 2.5/3.3/5 V
–2.5 V ↔ 3.3/5 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 pinout for easy PCB trace routing
•Latch-up performance >100 mA per JESD 17
•–40°C to 125°C operating temperature range
2 Applications
•GPIO, MDIO, PMBus, SMBus, SDIO, UART, I
2
C,
and other interfaces in telecom infrastructure
•Enterprise systems
•Communications equipment
•Personal electronics
•Industrial applications
3 Description
The LSF family of devices supports bidirectional
voltage translation without the need for DIR pin which
minimizes system effort (for PMBus, I
2
C, SMBus, and
so forth). The LSF family of devices 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 which allows the LSF family to support more
consumer or telecom interfaces (MDIO or SDIO).
LSF family supports 5-V tolerance on I/O port which
makes it compatible with TTL levels in industrial and
telecom applications. The LSF family is able to set up
different voltage translation levels which makes it very
flexible.
