TEXAS INSTRUMENTS Voltage Level Translator Bidirectional 4-Input TSSOP-14

The TEXAS INSTRUMENTS Voltage Level Translator is a 4-bit non-inverting translator IC that utilises two separate configurable power-supply rails. This device is designed to facilitate universal low-voltage bidirectional translation between various voltage nodes, including 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5V, making it highly versatile for mixed-voltage systems.

The A port tracks VCCA, accepting supply voltages from 1.2V to 3.6V, whilst the B port tracks VCCB, accepting voltages from 1.65V to 5.5V. Please note that VCCA must not exceed VCCB. When the output-enable (OE) input is low, all outputs are placed into a high-impedance state. To maintain this state during power up or down, the OE should be tied to GND through a pull-down resistor, with the minimum value determined by the current-sourcing capability of the driver.

Key Features

• VCC Isolation Feature: If either VCC input is at GND, all outputs default to a high-impedance state
• OE input circuit referenced to VCCA
• Low-power consumption with a maximum ICC of 5µA
• Ioff feature supports partial-power-down mode operation
• Latch-up performance exceeds 100mA per JESD 78, Class II
• Green product with no Antimony (Sb) or Bromine (Br)

Handling Precautions

This device has limited built-in ESD protection. To prevent electrostatic damage to the MOS gates, leads should be shorted together or the device placed in conductive foam during storage or handling.
