Parameter Measurement Information: VDD@3.3V–2.5V
Parameter Measurement Information: VDD@1.8V
Notes:
3. CL includes probe and jig capacitance.
4. All input pulses are supplied by generators having the following characteristics: PRR < 100 MHz, Z0 = 50Ω, tR < 2.5 ns, tF < 2.5 ns.
5. The outputs are measured one at a time with one transition per measurement.
6. TPLH and TPHL are the same as tpd.
AC Switching Characteristics @ 1.8V VDD = 1.8V ±5%, Temperature = –40°C to +85°C
