TXS0104EYZTR

The TXS0104EYZTR from Texas Instruments is a four-bit, non-inverting, bidirectional voltage-level translator designed for open-drain and push-pull applications. It operates with two separate configurable power-supply rails, VCCA and VCCB. The A port tracks VCCA, accepting voltages from 1.65 V to 3.6 V, while the B port tracks VCCB, accepting voltages from 2.3 V to 5.5 V. This configuration allows for seamless low-voltage bidirectional translation between common voltage nodes such as 1.8 V, 2.5 V, 3.3 V, and 5 V.

Key features include auto-direction sensing, eliminating the need for a direction-control signal. It supports maximum data rates of 24 Mbps for push-pull applications and 2 Mbps for open-drain applications. The device is available in the Texas Instruments NanoFree package, specifically the 12-DSBGA (YZT) package, which is surface-mount compatible.

Designed for reliability, the TXS0104EYZTR offers robust ESD protection exceeding JESD 22 standards on both ports. It also boasts latch-up performance exceeding 100 mA per JESD 78, class II. The device does not require power-supply sequencing, meaning VCCA or VCCB can be ramped first. When the output-enable (OE) input is low, all outputs are placed in a high-impedance state. The operating temperature range is -40°C to 85°C.
