Texas Instruments TPUL2G223/-Q1 Dual Monostable Multivibrators

Texas Instruments TPUL2G223/-Q1 Dual RC-Timed Retriggerable Monostable Multivibrators contain two independent RC-configurable retriggerable monostable multivibrators designed for 1.5V to 5.5V operation. The output pulse duration is set by selecting external resistance and capacitance values, with an approximate output pulse width of t_wo × R × C.

The TI TPUL2G223/-Q1 devices feature multiple trigger inputs for rising-edge and falling-edge triggering, along with an asynchronous clear input that can stop an active output pulse. The Schmitt-trigger architecture on all inputs supports slow input transition rates and improves noise immunity. These devices are available in a wettable-flank QFN package and offer RC configurability from 1µs to 860ms, with 1% typical and 10% maximum pulse-width variation.

The TPUL2G223/-Q1 is designed for applications such as demodulating a digital Amplitude Shift Keying (ASK) signal, resetting a system for a fixed period of time, generating a positive fixed-width digital pulse, detecting rising or falling digital signal edges, and debouncing a switch.

The TPUL2G223-Q1 are AEC-Q100 qualified and ideal for automotive applications.
