Texas Instruments TPUL2G123/-Q1 Dual RC-Timed Mono Multivibrators
Texas Instruments TPUL2G123/-Q1 Dual RC-Timed Retriggerable Monostable Multivibrators features two independent devices designed for 1.5V to 5.5V operation. The output pulse duration is formatted by choosing external resistance and capacitance values with an approximate output pulse width of two ≅ R × C.
The TI TPUL2G123-Q1 Dual Multivibrators includes three trigger inputs, one for rising-edge (T) and one for falling-edge (/T) triggers, and a clear input (/CLR) that can be used asynchronously to stop an active output pulse. All trigger inputs incorporate Schmitt-trigger architecture to enable slow input transition rates and improve noise immunity.
The TI TPUL2G123-Q1 Multivibrators are AEC-Q100 qualified for automotive applications.
