74ABT00D,118

Overview

The Nexperia 74ABT00D,118 is a quad 2-input NAND gate in an SO14 (SOT108-1) package. It operates on a supply voltage of 4.5 V to 5.5 V with BiCMOS technology for high speed and output drive. The device supports partial power-down via IOFF circuitry, preventing backflow current. Recommended operating conditions specify -40 °C to +85 °C ambient temperature. Static characteristics include a maximum LOW-level output voltage of 0.5 V at 20 mA load. Dynamic performance at 5.0 V includes a typical LOW-to-HIGH propagation delay of 2.5 ns and HIGH-to-LOW of 2.0 ns.

Feature Summary

• BiCMOS technology provides high-speed operation and strong output drive capabilities.
• IOFF circuitry enables partial power-down mode by disabling outputs to prevent damaging backflow currents.
• Direct interface compatibility with TTL logic levels simplifies system integration.

Applications

• Partial power-down applications requiring controlled backflow prevention
• High-speed digital logic processing circuits
• Systems interfacing between ABT and TTL logic families

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the 74ABT00 series includes both SO14 and TSSOP variants. Confirm that the application environment remains within the specified -40 °C to +85 °C temperature range. Ensure design safeguards account for the absolute maximum ratings to prevent permanent damage from stress conditions exceeding the defined limits.

Selection Notes

Select this component when a quad 2-input NAND function is required with BiCMOS speed advantages over standard CMOS. The SO14 package suits designs needing through-hole or standard surface-mount compatibility. Verify that the 4.5 V to 5.5 V supply range aligns with the system power architecture before finalizing the selection.

Part Context

This part belongs to the 74ABT logic family, characterized by BiCMOS technology offering higher speeds than standard 74HC devices. The 74ABT00 specifically implements four independent NAND gates. The 'D' designation indicates the SO14 plastic small outline package variant, distinct from the PW (TSSOP14) version.

Replacement Considerations

The 74ABT00PW,118 serves as a direct functional substitute utilizing the TSSOP14 package instead of the SO14 form factor. Other 74ABT00 variants may be considered if pin-compatible packaging adjustments are feasible within the target design constraints.

FAQ

How does the IOFF circuitry function during power-down?

The IOFF circuitry disables the outputs when the device is powered down, effectively preventing potentially damaging backflow current from flowing through the device.

What is the maximum recommended supply voltage?

The maximum recommended supply voltage (VCC) for the 74ABT00 is 5.5 V under recommended operating conditions.
