SN74AHC123ADGVR

Overview

The SN74AHC123ADGVR is a dual retriggerable monostable multivibrator from the Texas Instruments AHC logic family, housed in a 16-pin TVSOP package. It operates within a supply voltage range of 2V to 5.5V and supports an operating temperature range of -40°C to +85°C. The device features Schmitt-trigger circuitry on A, B, and CLR inputs for slow input transition rates. Edge triggering occurs from active-high or active-low gated logic inputs. Propagation delays are specified at 24ns (max) at VCC=3.3V with CL=50pF, and 16ns (max) at VCC=5V with CL=50pF.

Feature Summary

• Dual retriggerable monostable multivibrators designed for 2V to 5.5V VCC operation
• Schmitt-trigger circuitry on A, B, and CLR inputs for slow input transition rates
• Edge triggered from active-high or active-low gated logic inputs
• Glitch-free power-up reset on outputs

Applications

• Pulse generation and timing circuits
• Debouncing switches
• Frequency division
• Timing delay applications

Procurement Notes

Verify the specific ordering suffix 'DGVR' corresponds to the TVSOP-16 package and tape-and-reel carrier configuration. Confirm RoHS compliance and lead finish details via the manufacturer's official documentation. Ensure the component meets the required industrial temperature range specifications for the intended application environment.

Selection Notes

Select this component when dual independent monostable circuits are required in a compact surface-mount form factor. The AHC series offers high-speed performance suitable for modern digital systems. Verify that external timing components meet the recommended resistance and capacitance ranges for the desired pulse duration stability.

Part Context

This part belongs to the SNx4AHC123A family of dual retriggerable monostable multivibrators. The 'DGV' suffix indicates the TVSOP-16 package type, while 'RE4' denotes environmental compliance and packaging details. It is part of the broader AHC logic family known for high speed and low power consumption.

Replacement Considerations

SN74AHC123ADBR (SSOP-16), SN74AHC123ADR (SOIC-16), SN74AHC123APWR (TSSOP-16). Verify pinout compatibility and package dimensions before substitution.
