Low cost bidirectional voltage translation without directional control
Unlike level-shifting bus switches, which only translate between fixed voltages, these bidirectional low-voltage translators can translate any voltage between 1 and 5 V to any other voltage between 1 and 5 V. They also reduce ON-state resistance and minimize propagation delay.
Key features
► No directional control required for bidirectional voltage translations
► Low RON resistance (6.5 Ω) between input and output pins (Sn/Dn)
► Propagation delay: 1.5 ns (typ)
► Channel off-state capacitance: 7.5 pF
► Very low (5 µA) standby current
► No power supply required – prevents latch-ups
► Very small QFN package options
Applications
► Uni- and bidirectional translation for any voltage between 1 and 5 V
► Bidirectional translation of lowvoltage and legacy I2C-bus signals
► Shifting processor sideband I/O signals between GTL and LVTTL/TTL levels
