The 3-state outputs let you share a bus without contention, and the 32mA symmetric drive handles typical automotive loads like ECU-to-sensor interfaces or gateway-to-module links. ## Supply range and voltage-domain bridging Each supply pin accepts 1.65V to 5.5V independently, so you can translate between a 1.8V MCU and a 5V peripheral, or between 3.3V and 5V CAN transceivers, without an external level shifter. The device powers up with outputs in high-impedance state, preventing bus glitches during power sequencing. ## Output drive and bus architecture Each of the eight channels can source or sink 32mA, enough to drive a short twisted-pair stub or an LED indicator without a buffer. The 3-state control (active-low output enable per element) lets you isolate the bus during diagnostics or when the ECU enters sleep mode. Housed in a 24-TSSOP (4.40mm body width), the QPWRQ1 suffix indicates the automotive-qualified, tape-and-reel variant. The 0.65mm pitch is standard for this package class; the footprint matches the generic 24-TSSOP land pattern in most CAD libraries.","metaTitle":"SN74LVC8T245QPWRQ1 Translation Transceiver, AEC-Q100, 8-bit","metaDescription":"TI SN74LVC8T245QPWRQ1 is an automotive-grade 8-bit translation transceiver with 1.65V–5.5V supply, 32mA output drive, -40°C to 125°C.
