3 Description
This 4-bit non-inverting translator uses two separate
configurable power-supply rails. The A port is
designed to track VCCA. VCCA accepts any supply
voltage from 1.65 V to 3.6 V. VCCA must be less
than or equal to VCCB. The B port is designed to
track VCCB. VCCB accepts any supply voltage from 2.3
V to 5.5 V. This allows for low-voltage bidirectional
translation between any of the 1.8-V, 2.5-V, 3.3-V, and
5-V voltage nodes.
When the output-enable (OE) input is low, all outputs
are placed in the high-impedance state.
The TXS0104E is designed so that the OE input
circuit is supplied by VCCA.
For the high-impedance state during power up
or power down, tie OE to GND through a pulldown
resistor; the minimum value of the resistor is
determined by the current-sourcing capability of the
driver.
