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
