The TLV9023L-Q1 is a triple channel latching comparator with separate outputs and a combined AND output. The family also offers low input offset voltage, power on reset (POR), and fault-tolerant rail-to-rail inputs. These devices have an excellent speed-to-power combination with a propagation delay of 110ns with a quiescent supply current of only 25µA per channel.
The unique feature of the TLV9023L-Q1 is the output latching capability. The output latches upon the first high-to-low threshold crossing, allowing capture of an event or error condition without the full attention of a system controller. This allows events to be captured at start up while the system controller is still initializing or busy with other tasks. The falling-edge triggered clear input allows the system controller to reset the latch after performing any needed tasks and meets safety-critical requirements.
These comparators also feature fault-tolerant inputs that can go up to 6V without damage with no output phase inversion. This makes this family of comparators designed for precision voltage monitoring in harsh, noisy environments.
The TLV9023L-Q1 has open-drain outputs that can be pulled-up below or beyond the supply voltage for OR’ing multiple outputs or level translation. The AND output is push-pull to eliminate the need for a pull-up resistor and ensure output low start-up state.
The family is specified for the Automotive temperature range of -40°C to +125°C and are available in standard leaded and leadless packages.
