Product details

What the 2.9 V threshold and 140 ms timeout mean for your rail

The LTC694IN8-3.3#PBF: That 140 ms reset timeout gives downstream logic, a microcontroller or an FPGA time to complete its power-on initialization before the supervisor releases the reset line, preventing brown-out or startup glitches from corrupting state. The output is open drain or open collector, configurable as either active high or active low — this lets the designer pull the reset line to whatever logic voltage the supervised device needs, rather than being locked to the supervisor's own supply rail.

Through-hole DIP package and board-fit

Housed in an 8-DIP (0.300", 7.62mm) through-hole package with supplier device package 8-PDIP, this supervisor is a direct solder-in replacement for legacy socketed or wave-soldered designs — no reflow profile needed.

Frequently asked questions

How does LTC694IN8-3.3#PBF compare to ADM699ANZ?

Both are simple reset/power-on reset supervisors in through-hole DIP packages with the same reset type (active high/active low) and the same 140 ms minimum reset timeout. The ADM699ANZ uses a push-pull output stage, while the LTC694IN8-3.3#PBF uses an open drain or open collector output — check whether your pull-up resistor is already on the board before swapping them directly.
