#76914 - RE: Reset Generator for P89V51RD2
Responding to: ???'s previous message
Please be aware that the use of an additional CMOS inverter in between a low true output reset generator and the RESET input of a microcontroller where a high true RESET is required is not recommended. During the crucial time that the Vcc is transitioning from GND to +5 volts the reset generator chip itself will provide a predictable output condition even at the instant the Vcc is at say 0.96 volts. The CMOS inverters output state at this same voltage will not be predictable. As a matter of fact the inverter output most likely looks like it is in a tri-state condition!!

For this reason always select a reset generator that matches the RESET pin requirements of your microcontroller.
