74ABT08PW,118

Overview

The Nexperia 74ABT08PW,118 is a quad 2-input AND gate in the ABT logic series. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature from -40 °C to +85 °C. The device features BiCMOS technology for high speed and output drive capabilities. 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 3.4 ns and tPHL max 2.8 ns at 25 °C with VCC = 5.0 V. Latch-up protection exceeds 500 mA per JESD78B class II level A.

Feature Summary

• Includes IOFF circuitry to disable outputs during partial power-down, preventing damaging backflow currents.
• Provides direct interface compatibility with TTL logic levels.
• Features ESD protection exceeding 2000 V (HBM) and 1000 V (CDM).
• Offers robust latch-up protection exceeding 500 mA.

Applications

• Partial power-down applications requiring isolation of powered-down sections.
• Digital logic circuits utilizing standard 5V supply rails.
• Systems interfacing between CMOS and TTL logic families.

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the PW suffix denotes TSSOP14. Confirm that the application environment remains within the specified -40 °C to +85 °C temperature range. Ensure supply voltage constraints between 4.5 V and 5.5 V are strictly maintained to prevent exceeding absolute maximum ratings. Check for any recent Product Change Notifications regarding manufacturing site or material updates.

Selection Notes

Select this component when high-speed AND logic is required alongside direct TTL interfacing capabilities. The ABT series offers superior speed compared to standard HC/HCT logic while maintaining 5V operation. Consider the integrated IOFF feature if the design involves systems where parts of the circuit may be powered down while others remain active. Verify pinout compatibility with existing PCB layouts designed for standard 14-lead packages.

Part Context

This part belongs to the Nexperia 74ABT family of BiCMOS logic devices. The 'PW' suffix indicates the TSSOP14 plastic thin shrink small outline package (SOT402-1). The '118' suffix typically refers to the reel packaging format. It is functionally equivalent to other manufacturers' 74ABT08 devices but utilizes Nexperia's specific BiCMOS process technology.

Replacement Considerations

Cross-reference with other 74ABT08 variants from different manufacturers ensuring identical pinouts and electrical specifications. Verify that substitute components also support the required IOFF functionality if partial power-down is critical to the system design.

FAQ
