Texas Instruments TDEL3G510/-Q1 Triple Falling Edge Delay Elements
Texas Instruments TDEL3G510/-Q1 Triple Falling Edge Delay Elements contain three independent fixed-time delay blocks for digital timing applications. Each channel delays the falling edge of an input signal by a preset amount while allowing rising edges to pass through with minimal delay.
The TI TDEL3G510/-Q1 delivers preconfigured digital timing without external timing components, simplifying pulse shaping, signal debounce, and delay functions. The TDEL3G510/-Q1 Triple Falling Edge Delay Elements also use Schmitt-trigger inputs and I/O clamp diodes to support robust operation in systems exposed to overvoltage or undervoltage transients.
The delay elements are ideal for delaying falling-edge signals, extending short active-high pulses, filtering short active-low pulses, and debouncing active-high signals. The TDEL3G510/-Q1 is available in an 8-pin SOT-5X3 package and operates over a -40°C to +125°C temperature range.
