TC74HC02APF

Inverter Gates Overview

The TC74HC02APF is a Quad 2-Input NOR Gate fabricated with silicon gate C2MOS technology. It operates within a supply voltage range of 2V to 6V and supports an operating temperature from -40°C to 85°C. The device features a maximum quiescent current of 1 µA at 25°C and symmetrical output drive capability of 4 mA minimum. Propagation delay is typically 6 ns at VCC = 5V with a 15 pF load, rising to 13 ns typical at 50 pF load.

Inverter Gates Feature Summary

• High-speed operation comparable to LSTTL while maintaining CMOS low power dissipation
• Internal three-stage circuit design providing high noise immunity and stable output
• Integrated protection circuits on all inputs against static discharge or transient excess voltage

Inverter Gates Applications

• General electronics applications including computers and personal equipment
• Office equipment and measuring equipment logic circuits
• Industrial robots control systems
• Home electronics appliances

Inverter Gates Procurement Notes

Verify the specific package suffix 'PF' against official Toshiba documentation to confirm pinout and physical dimensions, as datasheets primarily list AP (DIP), AF (SOP), and AFN (JEDEC SOP). Ensure input pins are tied to VCC or GND if unused to maintain normal operation. Confirm compliance with applicable environmental regulations such as RoHS before integration into final products.

Inverter Gates Selection Notes

Select this component for designs requiring quad NOR logic functions in through-hole DIP packages. It serves as a functionally compatible replacement for 74LS02 devices while offering lower power consumption. Consider the 2V to 6V operating range when designing power supplies. Verify that the required propagation delay fits within system timing constraints under expected load capacitance conditions.

Inverter Gates Part Context

This part belongs to the TC74HC02A series of high-speed CMOS digital integrated circuits manufactured by Toshiba Semiconductor and Storage. The family includes variants with different packaging options such as DIP and SOP formats. These components are designed for general-purpose logic applications where speed and power efficiency are balanced requirements.

Inverter Gates Replacement Considerations

Direct functional substitutes include the CD74HC02E from Texas Instruments and the SN74HC02N from Rochester Electronics. These alternatives offer similar logic functionality and pin compatibility but may differ in specific electrical characteristics or manufacturing processes.
