Voltage Level Translator Bidirectional 1 Circuit 8 Channel 60Mbps 20-TSSOP
This device is an 8-bit non-inverting level translator
which uses two separate configurable power-supply
rails. The A port tracks the VCCA pin supply voltage.
The VCCA pin accepts any supply voltage between
1.4V and 3.6V. The B port tracks the VCCB pin
supply voltage. The VCCB pin accepts any supply
voltage between 1.65V and 5.5V. Two input supply
pins allows for low Voltage bidirectional translation
between any of the 1.5V, 1.8V, 2.5V, 3.3V, and 5V
voltage nodes.
When the output-enable (OE) input is low, all outputs
are placed in the high-impedance (Hi-Z) state.
To put the device in the Hi-Z state during power-up
or power-down periods, tie OE to GND through a pulldown resistor. The current-sourcing capability of the
driver determines the minimum value of the resistor.
• No direction-control signal needed
• Maximum data rates:
– 110Mbps (push pull)
– 1.2Mbps (open drain)
• 1.4V to 3.6V on A port and 1.65V to 5.5V on B port
