7.1 Overview

The TPUL1G313-Q1 device contains one extended-pulse-width retriggerable monostable multivibrator circuit. A monostable multivibrator, also commonly known as a one shot, produces a single digital pulse when triggered and otherwise maintains a constant output state.

The TPUL1G313-Q1 device features three gated trigger inputs for each channel. For a rising edge trigger, the T or CLR input is used. For a falling edge trigger the T input is used.

The TPUL1G313-Q1 device includes an asynchronous clear input (CLR) that can be used to terminate an ongoing output pulse.

When triggered, the TPUL1G313-Q1 outputs a positive digital pulse with pulse width defined as two = 1024 × K × Rext × Cext, with Rext and Cext being the external timing resistor and external timing capacitor component values measured in Ω and F, respectively, and K being a unitless nonlinearity correction factor provided in the Typical Characteristics section. The external timing components must be connected as shown in Figure 7-1. The external ground connection to the C terminal is optional.
