74ABT08DB,112

Overview

The 74ABT08DB,112 is a quad AND gate manufactured by Nexperia USA Inc. It operates within a supply voltage range of 4.5 V to 5.5 V and utilizes BiCMOS technology for high-speed performance. The device features four independent two-input AND gates in a 14-pin SSOP package. Key electrical parameters include a maximum propagation delay of 3.6 ns at 5 V and output drive capabilities of +24 mA (high) and -12 mA (low). It supports partial power-down mode via Ioff circuitry and includes latch-up protection exceeding 500 mA per JESD78 standards.

Feature Summary

• High-speed BiCMOS logic implementation
• Partial power-down capability with Ioff circuitry
• Latch-up protection exceeding 500 mA

Applications

• Bus interface applications
• Clock distribution circuits
• Data acquisition systems

Procurement Notes

Verify the specific ordering code 935174030112 against official Nexperia documentation to confirm availability status. Confirm that the SSOP-14 package variant matches the required footprint for PCB layout. Ensure compliance with RoHS directives if applicable to the target assembly process. Check for any recent Product Change Notifications regarding marking or packaging updates.

Selection Notes

Select this component when high-speed AND logic is required within a standard 5 V system environment. The BiCMOS technology offers superior speed compared to standard CMOS alternatives while maintaining compatibility with TTL input levels. Verify that the 14-pin SSOP package dimensions fit the mechanical constraints of the design. Consider the Ioff feature if the application requires safe disconnection during partial power-down states.

Part Context

This part belongs to the 74ABT series of advanced BiCMOS logic devices from Nexperia. The series is designed for high-performance digital applications requiring fast switching speeds. The 74ABT08 specifically provides quad AND functionality. It is distinct from the LVC or HC series due to its higher speed and specific 5 V operating voltage range.

Replacement Considerations

Check for direct substitutes such as the 74ABT08PW variant if a TSSOP package is preferred. Verify pinout compatibility before replacing with other manufacturers' 74ABT08 equivalents.
