Reset timeout: 140ms minimum
The 140ms minimum reset timeout gives the power supply and oscillator time to stabilise before the processor starts executing code. That is long enough for most ceramic-cap-based regulators and crystal oscillators to reach steady state, but if you have a slow-start supply or a large bulk capacitor on the rail, verify that the 140ms window is sufficient — otherwise the processor may attempt to boot before the rail is fully settled.
Active-high and active-low output — one part, two polarities
The push-pull output can be configured for either active-high or active-low reset. That means the same part can drive a active-low /RESET pin on an MCU or an active-high enable pin on a regulator or FPGA. No external inverter needed, which saves a resistor or a gate. The push-pull topology also eliminates the need for a pull-up resistor that an open-drain output would require.
Lifecycle and sourcing reality
It is ROHS3 compliant. For BOM planning, this part can be designed into new builds without immediate obsolescence risk.
