The MAX3453E-MAX3456E ±15kV ESD-protected USB-compliant transceivers interface low-voltage ASICs with USB devices. The devices fully comply with USB 1.1 and USB 2.0 when operating at full (12Mbps) and low (1.5Mbps) speeds.
The Maxim MAX3453E‑MAX3456E family provides USB‑compliant transceivers with up to +15 kV ESD protection on the D+ and D‑ lines. They operate from a low‑voltage logic supply (VL) of 1.65 V to 3.6 V and support full‑speed (12 Mbps) USB operation, with the MAX3453E limited to full‑speed only.
The devices include a selectable suspend mode that reduces current draw to under 40 µA, internal voltage regulation (VTRM 3.0‑3.6 V), and a range of package options (14‑pin TSSOP, 16‑pin thin QFN). Pin‑compatible variants such as the MAX3456E match Micrel’s MIC2550A, simplifying board redesigns.
| Regulated Supply Voltage (VTRM) range | 3.0 V – 3.6 V |
|---|---|
| Logic Supply Voltage (VL) range | 1.65 V – 3.6 V |
| ESD protection rating | +15 kV on D+ and D‑ |
| Operating temperature range | -40 °C to +85 °C |
| Suspend mode current consumption | < 40 µA |
The MAX3453E supports only full‑speed (12 Mbps) operation.
The MAX3456E is pin compatible with Micrel’s MIC2550A.
In suspend mode the device draws less than 40 µA.
