PE4280
Product Specification
Latch-Up Avoidance
Unlike conventional CMOS devices, UltraCMOS™
devices are immune to latch-up.
Switching Frequency
The PE4280 has a maximum 25 kHz switching
rate when the internal negative voltage generator
is used (pin 18 = GND). The rate at which the
PE4280 can be switched is only limited to the
switching time if an external -3 V supply is
provided at pin 18 (VSS).
