• Manufacturer Part Number: pef2045
• Description: Memory Time Switch Cmos Mtsc
• Manufacturer: Infineon Technologies Corporation

AC Characteristics
Ambient temperature under bias range,
Inputs are driven at 2.4 V for a logical 1 and at 0.4 V for a logical 0. Timing measurements are made
at 2.0 V for a logical 1 and at 0.8 V for a logical 0. The AC testing input/output waveforms are shown
below.
