SN74AHCT123ADBR

Overview

The SN74AHCT123ADBR is a dual retriggerable monostable multivibrator from the Texas Instruments SN74AHCT123A series. It operates within a supply voltage range of 4.5 V to 5.5 V and features two independent circuits per package. The device utilizes edge-triggered inputs derived from active-high or active-low gated logic, allowing for flexible timing control. It is housed in a 16-pin SOIC (Narrow) surface-mount package and supports operation across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Dual retriggerable monostable multivibrator architecture providing two independent timing channels
• Edge-triggered functionality compatible with active-high or active-low gated logic inputs
• Industrial operating temperature range supporting -40°C to +85°C environments

Applications

• Pulse width generation and shaping
• Timing delay applications
• Frequency division circuits

Procurement Notes

Verify that the specific order suffix matches the required package type and temperature grade. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure input signal levels are compatible with the specified 4.5 V to 5.5 V supply voltage range to prevent functional errors.

Selection Notes

Select this component when dual independent monostable timing channels are required in a narrow SOIC package. The AHCT series ensures compatibility with standard CMOS logic families while maintaining TTL-compatible input thresholds. Verify that the 4.5 V minimum supply voltage aligns with the system power design constraints.

Part Context

This part belongs to the SN74AHCT123A family of dual retriggerable monostable multivibrators. The 'AHCT' designation indicates high-speed CMOS technology with TTL-compatible inputs. The 'DBR' suffix specifies the 16-SOIC narrow package with tape-and-reel packaging configuration for automated assembly processes.

Replacement Considerations

Cross-reference with other SN74AHCT123 variants such as SN74AHCT123ADR or SN74AHCT123ADGVR for alternative package options. Verify pinout compatibility and electrical specifications before substituting.
