SN74AHCT00PW

Overview

The SN74AHCT00PW is a quad 2-input positive-NAND gate from the Texas Instruments SN74AHCT00 series. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a wide operating temperature range from -40°C to +125°C. The device features low output drive capability with 8 mA sink and source currents, and typical propagation delays of 5.5 ns. Packaged in a TSSOP-14 surface-mount format, it ensures compatibility with TTL-driven interfaces while maintaining CMOS performance characteristics.

Feature Summary

• Integrates four independent 2-input NAND logic gates within a single package
• Provides full compatibility with TTL input levels for seamless interface integration
• Supports extended industrial temperature ranges for reliable operation in harsh environments

Applications

• General-purpose digital logic processing circuits
• Interface bridging between TTL and CMOS logic domains
• Signal gating and control logic in embedded systems

Procurement Notes

Verify the exact suffix against official documentation to confirm pinout and electrical specifications. Confirm RoHS compliance status and specific manufacturing lot requirements before procurement. Ensure the selected variant matches the required operating temperature range and package tolerance for your specific application design constraints.

Selection Notes

Select this component when TTL-compatible inputs are required alongside CMOS performance. Verify that the 4.5 V minimum supply voltage aligns with your system power rails. Consider the TSSOP-14 thermal dissipation capabilities if multiple gates are actively switching simultaneously under load conditions.
