(Talon revision 1.5 and earlier)
0 – 5V (Talon revision 1.6 and on)
Data Port Max Current
3.3V (pin1) : 33mA

Note 1: This is based on the maximum quadrature edge-to-edge rating of 187.5ns.
Note 2: A late errata on the microcontroller was released after Talon SRX 2015 season production, indicating the Quad B and Quad Idx are
not 5V tolerant. As a result, Talons with revision 1.5 (and earlier) should not use sensor cable/breakouts that allow >3.6V on Quad B or Quad
Idx, as this may damage Talon SRX. See Talon SRX Software Reference Manual (Section 2) for how to detect Hardware Revision. See
Section 1.4.6.1 for the updated breakout solution.
