TXB0104
SCES650I – APRIL 2006 – REVISED MARCH 2018
TXB0104 4-Bit Bidirectional Voltage-level Translator With Automatic Direction Sensing
and ±15-kV ESD Protection
1 Features
1 1.2-V to 3.6-V on A Port and 1.65-V to 5.5-V
on B Port (VCCA VCCB)
• VCC Isolation Feature: If Either VCC Input Is at
GND, All Outputs Are in the High-Impedance
State
• Output Enable (OE) Input Circuit Referenced to
VCCA
• Low Power Consumption, 5-μA Maximum ICC
• 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)
– 1500-V Charged-Device Model (C101)
– B Port:
– ±15-kV Human-Body Model (A114-B)
– 1500-V Charged-Device Model (C101)
3 Description
This TXB0104 4-bit noninverting translator uses two
separate configurable power-supply rails. The A port
is designed to track VCCA. VCCA accepts any supply
voltage from 1.2 V to 3.6 V. The B port is designed to
track VCCB. VCCB accepts any supply voltage from
1.65 V to 5.5 V. This allows for universal low-voltage
bidirectional translation between any of the 1.2-V,
1.5-V, 1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes.
VCCA must not exceed VCCB.
When the OE input is low, all outputs are placed in
the high-impedance state. To ensure the high-
impedance state during power up or power down, OE
must be tied to GND through a pulldown resistor The
current sourcing capability of the driver determines
the minimum value of the resistor.
The TXB0104 device is designed so the OE input
circuit is supplied by VCCA.
This device is fully specified for partial power-down
applications using I OFF. The I OFF circuitry disables
the outputs, which prevents damaging current
backflow through the device when the device is
powered down.
