74AHCT02PW,112

Overview

The Nexperia 74AHCT02PW,112 is a high-speed Si-gate CMOS quad 2-input NOR gate. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible input levels. The device provides balanced propagation delays and includes Schmitt-trigger action on all inputs for improved noise immunity. It supports partial power-down via I_OFF circuitry and offers ESD protection exceeding 2000 V (HBM) and 1000 V (CDM). Packaged in a TSSOP14 (SOT402-1) housing with a body width of 4.4 mm, it functions reliably from -40 °C to +125 °C.

Feature Summary

• Provides a quad 2-input NOR logic function compatible with Low-power Schottky TTL pinouts.
• Features Schmitt-trigger action on all inputs to tolerate slower rise and fall times.
• Includes I_OFF circuitry to disable outputs during partial power-down conditions.
• Accepts input voltages higher than the supply voltage VCC.

Applications

• General-purpose digital logic applications requiring NOR functionality.
• Systems interfacing between TTL-level sources and CMOS-level loads.
• Partial power-down scenarios utilizing I_OFF output disabling capabilities.

Procurement Notes

Verify the specific ordering suffix '112' corresponds to the TSSOP14 package variant when sourcing. Confirm that the application environment remains within the specified 4.5 V to 5.5 V supply voltage range to ensure proper operation. Check for any recent Product Change Notices regarding marking or assembly updates before finalizing procurement plans.

Selection Notes

Select this component when a quad 2-input NOR gate with TTL-compatible input thresholds is required. Ensure the design accommodates the 4.5 V to 5.5 V operating voltage range. Consider the TSSOP14 package dimensions if space constraints are a factor. Verify that the required ESD protection levels meet the system's environmental standards.

Part Context

This part belongs to the 74AHC/AHCT family of high-speed silicon-gate CMOS logic devices. The AHCT series specifically bridges the gap between CMOS technology and TTL logic levels, allowing direct interface with legacy TTL systems while maintaining CMOS low power consumption characteristics.
