Describe：SN74LVC1G123DCUR is a single-channel retriggerable monostable multivibrator (monostable trigger) launched by Texas Instruments. It is packaged in a VSSOP-8 micro surface-mount package. This device belongs to the 74LVC series and is designed to operate within a wide voltage range of 1.65V to 5.5V. The core function of this device is to output a timing pulse with a programmable width after the input pulse is triggered. The duration of the output pulse is precisely controlled by selecting the external resistor (R_ext) and capacitor (C_ext). What makes it unique is its retriggerable feature, which allows the output pulse to be extended by a new input trigger signal before the end of the first output pulse. This is highly suitable for generating extremely long timing or implementing pulse width modulation (PWM). This device integrates a Schmitt trigger circuit at the A and B input terminals, capable of handling slowly varying input signals and achieving undisturbed triggering at the output terminal. The output pulse can be triggered in two ways: by making the A input low and the B input high; or by making the clear (CLR) input high. The CLR input can also be used to forcibly terminate the output before the pulse ends. The main performance indicators are as follows: propagation delay of 18.5 ns, output drive capability of ±32 mA, and static current of only 20 µA. The input can withstand a maximum voltage of 5.5 V, and supports mixed-mode voltage operation and downward conversion to the Vcc level conversion function. This device fully complies with automotive-grade temperature requirements (-40°C to +125°C), and features Ioff power-off protection, latch-up performance exceeding 100mA (JESD 78 Class II), and high-level ESD protection.
