74ABT08DB,118

Overview

The Nexperia 74ABT08DB,118 is a quad 2-input AND gate manufactured by Nexperia USA Inc. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +85 °C. The device features BiCMOS technology for high-speed performance and direct interface with TTL levels. Key electrical parameters include a LOW-level output current of 20 mA and a HIGH-level output current of -15 mA. Propagation delays are specified as tPLH max 4.0 ns and tPHL max 3.0 ns at VCC = 5.0 V. The component utilizes the SO14 (SOT108-1) plastic small outline package.

Feature Summary

• Incorporates IOFF circuitry to disable outputs during partial power-down, preventing damaging backflow currents.
• Provides latch-up protection exceeding 500 mA per JESD78B class II level A standards.
• Features ESD protection capabilities exceeding 2000 V via Human Body Model and 1000 V via Charged Device Model.

Applications

• Partial power-down applications requiring controlled output disabling
• Quad bus interface systems
• Direct interfacing with TTL logic levels

Procurement Notes

Verify that the specific ordering suffix 'DB' corresponds to the requested package variant, as official documentation lists 'D' for SO14 and 'PW' for TSSOP14. Confirm the manufacturer designation matches Nexperia USA Inc. requirements. Ensure the product status aligns with current production data sheets before finalizing procurement orders.

Selection Notes

Select this component when BiCMOS high-speed operation and direct TTL compatibility are required within a 4.5 V to 5.5 V supply range. The inclusion of IOFF circuitry makes it suitable for designs needing partial power-down functionality. Verify that the SO14 package dimensions meet the PCB layout constraints compared to alternative packages like TSSOP14.

Part Context

The 74ABT08 series belongs to Nexperia's ABT logic family, characterized by BiCMOS technology offering high speed and strong output drive capabilities. This specific part implements four independent 2-input AND gates in a single integrated circuit. The family is designed for general-purpose digital applications requiring reliable switching performance and robust protection against electrostatic discharge and latch-up events.

Replacement Considerations

The datasheet revision history explicitly states that type number 74ABT08DB was removed in version 4.0. No public substitute part numbers are confirmed in the provided source material.
