Single-Ended I/O Characteristics
3.3 V LVTTL / 3.3 V LVCMOS
Low-Voltage Transistor–Transistor Logic (LVTTL) is a general-purpose standard (EIA/JESD) for 3.3 V
applications. It uses an LVTTL input buffer and push-pull output buffer.

Notes:
1. IIL is the input leakage current per I/O pin over recommended operation conditions where –0.3 V < VIN < VIL.
2. IIH is the input leakage current per I/O pin over recommended operating conditions VIH < VIN < VCCI. Input current is
larger when operating outside recommended ranges.
3. Currents are measured at high temperature (100°C junction temperature) and maximum voltage.
4. Currents are measured at 85°C junction temperature.
5. Software default selection highlighted in gray.

Notes:
1. Measuring point = Vtrip. See Table 2-16 on page 2-17 for a complete table of trip points.
2. Capacitive Load for A3PN060, A3PN125, and A3PN250 is 35 pF.
