Technical specifications
| Specification | Value | Notes |
|---|---|---|
| Comparator channels | 4 | |
| Single-supply operation | 3.3 V or 5.0 V | Operating-supply feature; electrical limits are specified at +5.0 V unless otherwise stated. This does not establish 3.3 V post-radiation characterization. |
| Input signal range | Within the included power-supply range | |
| Ordered radiation assurance | 1 Mrad(Si) | Only the exact 5910-901-1S RHA ordering option; dose-rate conditions remain per datasheet. Published family dose rate: 50–300 rad(Si)/s. Irradiation bias and electrical-test supply conditions must follow the datasheet; no assurance at an uncharacterized voltage is implied. |
Values are subject to the conditions and ordering options in the referenced product documentation.
Product overview
The RHD5910 provides four high-speed comparators for continuous comparison of dynamic input signals. Each comparator behaves as a high-gain, open-loop amplifier with a digital output, accepting input signals within the included supply range. The design uses specific circuit topology and layout methods to mitigate ionizing-dose effects and single-event latchup. Inputs and outputs include diode protection, and the CMOS output stages tolerate momentary shorts. External feedback hysteresis is the designer’s responsibility where slow signals or small input differences could cause noise-driven output transitions. Screening and radiation assurance depend on the ordering option.
