ISL3035E CLOCK WAVEFORMS (100Mbps)
• Voltage range
ƒ +1.35V < V_L < +3.2V (lower voltage logic supply)
ƒ +2.2V < V_CC < +3.6V (higher voltage peripheral supply)
• Fast data rates
ƒ 100Mbps for V_L ≥ 1.62V
ƒ 85Mbps for V_L ≥ 1.35V
• Auto-direction sensing
• IEC61000-4-2 ESD protection on the V_L and V_CC I/O pins
ƒ 15kV air gap, 9kV contact
• 6 bidirectional channels
ƒ ISL3035E - Additional clock return pin
ƒ ISL3034E - Enable pin for software-controlled power down
• 4 bidirectional channels
ƒ ISL3036E - Enable pin for software-controlled power down
• Industrial temp range (-40°C to +85°C)
• Small TQFN and μTQFN package options
Why are level shifters needed?
• Simplifies the interconnection between two ICs
operating at different supply voltages
ƒ Interface components (RS-232/RS-485
transceivers, memory cards, etc.) typically
operate at supply voltages of 3.3V or higher
ƒ Core components (baseband processors,
μControllers, ASICs, and FPGAs) operate at
lower supply voltages (currently 1.8V)
ƒ Lower V_CC logic typically cannot drive higher
V_CC logic without translation circuitry
• Dual-supply level shifters solve the interfacing
problem
ƒ Shifts logic levels up/down to be compatible
with each of the supply voltages
ƒ Gives designers more flexibility in choosing
components for the application
