74ABT08D,118

Overview

The Nexperia 74ABT08D,118 is a quad 2-input AND gate manufactured using BiCMOS technology. It operates within a supply voltage range of 4.5 V to 5.5 V and supports direct interface with TTL levels. The device features IOFF circuitry for partial power-down applications, preventing backflow current when powered down. Latch-up protection exceeds 500 mA per JESD78B Class II Level A standards. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM). Propagation delays are specified from 1.0 ns to 4.0 ns at 5.0 V. Operating temperature ranges from -40 °C to +85 °C.

Feature Summary

• BiCMOS high-speed performance with strong output drive capabilities
• IOFF circuitry enables safe partial power-down mode operation
• Robust latch-up protection exceeding 500 mA per JESD78B Class II Level A
• Direct interface compatibility with TTL logic levels

Applications

• Partial power-down systems requiring backflow current prevention
• High-speed digital logic processing circuits
• Mixed-signal interfaces involving TTL level translation

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the 'D' designation indicates an SO14 plastic small outline package. Confirm that the application environment remains within the specified -40 °C to +85 °C operating temperature range. Ensure supply voltage constraints between 4.5 V and 5.5 V are strictly maintained during operation to prevent exceeding absolute maximum ratings.

Selection Notes

Select this component for designs requiring fast switching speeds and robust noise immunity in standard 5 V logic environments. The inclusion of IOFF functionality makes it suitable for battery-powered or standby-sensitive systems where leakage reduction is critical. Verify that the thermal dissipation requirements align with the SO14 package limitations under maximum load conditions.

Part Context

This part belongs to the 74ABT series of advanced BiCMOS logic devices, designed for high-speed applications. It serves as a fundamental building block for complex digital systems requiring reliable AND logic operations. The device complements other members of the 74ABT family, offering standardized pinouts and electrical characteristics for easy integration into existing logic architectures.

Replacement Considerations

Cross-reference with other 74ABT08 variants from different manufacturers if package availability is constrained. Ensure any substitute maintains identical BiCMOS speed characteristics and IOFF functionality to preserve system integrity during partial power-down states.
