SN74AHCT00N

Overview

The SN74AHCT00N 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 features TTL-compatible inputs. The device provides four independent NAND gates in a 14-pin PDIP package. Key electrical specifications include a propagation delay of 8 ns, low-level output current of 5.2 mA, and high-level output current of -5.2 mA. It supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Contains four independent 2-input NAND logic gates
• Features TTL-compatible input levels for direct interface with TTL signals
• Provides standard push-pull outputs with defined drive capabilities

Applications

• General-purpose digital logic signal processing
• Interface circuits requiring TTL-to-CMOS level translation
• Boolean logic implementation in embedded systems

Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm pinout compatibility and electrical characteristics. Ensure the procurement channel sources genuine components to avoid counterfeit risks. Confirm that the PDIP-14 package variant matches the target PCB footprint requirements before finalizing orders.

Selection Notes

Select this component when TTL-compatible inputs are required alongside CMOS performance. The AHCT series bridges the gap between older TTL logic families and modern CMOS technologies. Verify that the 4.5 V to 5.5 V supply voltage range aligns with the system power rails and that the 8 ns propagation delay meets the timing constraints of the application.

Part Context

This part belongs to the SN74AHCT00 family of single-function logic gates. It shares functional similarities with other quad NAND gates but is distinguished by its AHCT logic series, which ensures compatibility with TTL input standards while utilizing CMOS technology for lower power consumption and higher noise immunity compared to traditional bipolar logic families.

Replacement Considerations

SN74AHCT00PW: Same logical function and electrical characteristics housed in a TSSOP-14 surface-mount package instead of the through-hole PDIP-14 configuration.
