Product data sheet Rev. 01 — 15 February 2007 12 of 24 NXP Semiconductors ISP1102A Advanced USB transceiver [1] VOH(min) = V(VREG3V3) − 0.2 V. [2] Includes external resistors of 33 Ω± 1 % on both pins DP and DM. [3] This voltage is available at pins VREG3V3 and VPU3V3. [4] The minimum voltage is 2.7 V in suspend mode. 12. Dynamic characteristics Table 13. Static characteristics: analog I/O pins DP and DM VCC(5V0) = 4.0 V to 5.5 V or V(VREG3V3) = 3.0 V to 3.6 V; VGND = 0 V; Tamb = −40 °C to +85 °C; unless otherwise specified.
