Texas Instruments TPUL2G123/-Q1 Dual RC-Timed Mono Multivibrators

Introduction

The Texas Instruments TPUL2G123/-Q1 is a versatile dual RC-timed retriggerable monostable multivibrator designed for a wide range of applications. Operating within a voltage range of 1.5V to 5.5V, this component is particularly suitable for automotive applications due to its AEC-Q100 qualification.

Part Description

The TPUL2G123/-Q1 features two independent devices that can be configured to generate output pulses of varying durations, determined by external resistance and capacitance values. Each device includes three trigger inputs: one for rising-edge triggers, one for falling-edge triggers, and a clear input (CLR) for asynchronous control of active output pulses. The Schmitt-trigger architecture on all inputs enhances noise immunity and allows for slow input transition rates, making it ideal for various electronic applications.

Applications

• Demodulating digital Amplitude Shift Keying (ASK) signals
• Resetting systems for fixed periods
• Generating positive fixed-width digital pulses
• Detecting rising edges of digital signals
• Detecting falling edges of digital signals
• Debouncing switches
