TXS***4E-Q1 Automotive *-Bit Bidirectional Voltage-Level Translator for Open-Drain and Push-Pull Applications. the TXS***4E-Q2 device connects an incomptiable logic communication for chip to chip due to voltage mismatch. This auto-direction translator can be conveniently used to bridge the gap without the need of direction control from the host. Each channel can be mixed and matched with different output types (open-drain or push-pull) and mixed data flows (transmit or receive) without intervention from the host. This *-bit noninverting translator uses two separate configurable power-supply rails. The A and B ports are designed to track VCCA and VCCB respectively. The VCCB pin accepts any supply voltage from 2.3 V to 5.5 V while the VCCA pin accepts any supply voltage from 1.*5 V to 3.6 V such that VCCA is less than or equal to VCCB. This tracking allows for low-voltage bidirectional translation between any of the 1.*-V, 2.*-V, 3.*-V, and *-V voltage nodes. When the output-enable (OE) is low, all outputs are placed in the high-impedance state. The TXS***4E-Q1 device is designed so that the OE circuit is supplied by VCCA.
