Overview
The TPT20108 device is an 8-bit level shift with an enable (OE) input and can work from 1.65 V to 3.6 V VCCA and 1.65 V to 5.5 V VCCB. VCCA must be less than or equal to VCCB. The TPT20108 supports bidirectional voltage translation among 1.8 V, 2.5 V, 3.3 V, and 5 V.
The A1~8 I/Os are connected to the B1~8 I/Os, which allows bidirectional data flow between ports. If OE is low, the translator switch is off, and a High-impedance state exists between A port and B port to isolate both sides. OE input circuit is internally connected to VCCA.
The 8-bit bidirectional buffer isolates capacitance and allows 15 pF on either side of the device to support 100-Mbps speed in Push-Pull mode in 3.3 V-VCCA and 5-V VCCB supply, and supports 1.2-Mbps speed in Open-Drain mode.
TPT20108 is available in TSSOP20 and QFN3.5x4.5-20 packages and is characterized from −40°C to +125°C.
