TXB0108 SCES643H – NOVEMBER 2006 – REVISED AUGUST 2020 TXB0108 8-Bit Bidirectional Voltage-Level Translator with Auto-Direction Sensing and ±15-kV ESD Protection 1 Features 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 OE Input Circuit Referenced to VCCA Low Power Consumption, 4-μA Max ICC Ioff Supports Partial-Power-Down Mode Operation Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II ESD Protection Exceeds JESD 22 – A Port 2000-V Human-Body Model (A114-B) 1000-V Charged-Device Model (C101) – B Port ±15-kV Human-Body Model (A114-B) ±8-kV Human-Body Model (A114-B) (YZP Package Only) 1000-V Charged-Device Model (C101) 2 Applications Handset Smartphone Tablet Desktop PC VCCA 3 Description This 8-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, 1.5V, 1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes. VCCA should not exceed VCCB. When the output-enable (OE) input is low, all outputs are placed in the high-impedance state. The TXB0108 is designed so that the OE input circuit is supplied by VCCA.
