CHT-555 Description
The CHT-555 is a high-temperature, lowpower, highly stable device for generating accurate time delays or oscillation. It can be used as a high-temperature direct replacement of the standard 555. Because of its high input impedance, this device allows the use of smaller capacitors than those used by the standard 555, then providing more accurate time delays and oscillations, as well as cheaper BOM.
