AEC-Q100 4-bit auto-direction level translator, 1.65-5.5 V, 24 Mbps, TSSOP-14
The TXS0104E-Q1 is an automotive 4-bit bidirectional voltage-level translator with automatic direction sensing, so no direction-control signal is required. The A port operates from 1.65 V to 3.6 V and the B port from 2.3 V to 5.5 V, with VCCA not exceeding VCCB. It handles open-drain signals up to 2 Mbps and push-pull signals up to 24 Mbps, and includes an output-enable input and IEC 61000-4-2 protection on the B port. Typical uses are I2C, SMBus, SPI, UART, MDIO, SDIO, JTAG and GPIO level shifting.

Quality & Traceability
Cerametronics is ISO 9001 certified and products are RoHS compliant, with counterfeit screening and full traceability on every shipment. A Certificate of Conformance is available on request. For allocation-sensitive or high-risk lots, independent third-party lab verification can be arranged — just flag it on your RFQ. Any lot that fails incoming inspection is quarantined and never shipped.
FAQ
Does the TXS0104E-Q1 need a direction-control pin?
No. Each of the four channels senses direction automatically and works with both open-drain and push-pull signals. An OE input can disable the outputs.
Is power-supply sequencing required?
No sequencing is required, but VCCA must stay at or below VCCB (VCCA 1.65 V to 3.6 V, VCCB 2.3 V to 5.5 V).
