TXS0102YZPR General Description

This two-bit non-inverting translator is a bidirectional voltage-level translator and can be used to establish digital switching compatibility between mixed-voltage systems. It uses two separate configurable power-supply rails, with the A ports supporting operating voltages from 1.65 V to 3.6 V while it tracks the V CCA supply, and the B ports supporting operating voltages from 2.3 V to 5.5 V while it tracks the V CCB supply. This allows the support of both lower and higher logic signal levels while providing bidirectional translation capabilities 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 I/Os are placed in the high-impedance state, which significantly reduces the power-supply quiescent current consumption.

To ensure the high-impedance state during power up or power down, OE should be tied to GND through a pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.

Key Features

No direction-control signal needed
Maximum data rates:
- 24 Mbps (push pull)
- 2 Mbps (open drain)
Available in the Texas Instruments NanoStar™ integrated circuit package
1.65 V to 3.6 V on A port and 2.3 V to 5.5 V on B port (V CCA ≤ V CCB)
V CC isolation feature: if either V CC input is at GND, both ports are in the High-Impedance state
No power-supply sequencing required: either V CCA or V CCB can be ramped first
I off supports partial-power-down mode operation
Latch-up performance exceeds 100 mA per JESD 78, Class II
ESD protection exceeds JESD 22:
- A port:
  - 2500-V Human-Body Model (A114-B)
  - 250-V Machine Model (A115-A)
  - 1500-V Charged-Device Model (C101)
- B port:
  - 8-kV Human-Body Model (A114-B)
  - 250-V Machine Model (A115-A)
  - 1500-V Charged-Device Model (C101)
