SN74AHCT123ADGVR

Overview

The SN74AHCT123ADGVR is a dual retriggerable monostable multivibrator from Texas Instruments, housed in a 16-pin TVSOP package. It operates within a supply voltage range of 2 V to 5.5 V and supports standard CMOS logic levels with HCT input compatibility. The device features edge-triggered inputs from active-high or active-low gated logic, allowing flexible timing control. Designed for industrial applications, it functions reliably across an extended temperature range from -40°C to +85°C. This component provides precise pulse generation and timing delay capabilities for digital systems.

Feature Summary

• Dual independent retriggerable monostable multivibrator circuits
• HCT-compatible inputs for direct interface with TTL logic
• Edge-triggered operation from active-high or active-low gated inputs

Applications

• Pulse width modulation signal generation
• Timing delay circuits in digital systems
• Debouncing switches for clean digital transitions

Procurement Notes

Verify the specific suffix 'DGVR' confirms the TVSOP-16 package and reel packaging format. Ensure the operating voltage requirements align with your system's 2V to 5.5V range. Confirm thermal management needs for the -40°C to +85°C industrial temperature grade. Check for RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when dual independent timing channels are required in a compact surface-mount package. The HCT input compatibility makes it suitable for interfacing directly with older TTL-based logic families without level shifting. Consider the TVSOP-16 form factor for space-constrained designs requiring robust industrial temperature performance.

Part Context

This part belongs to the SN74AHCT123A series of monostable multivibrators. It shares functional similarities with other devices in the AHCT/VHCT/VT family but offers specific HCT input thresholds. The ADGVR designation indicates the automotive-grade or industrial-grade variant with specific packaging and testing parameters defined by Texas Instruments.

Replacement Considerations

SN74AHCT123ADGVRE4 is a verified replacement with identical functionality and pinout.
