SN74F02DR

Overview

The SN74F02DR is a quadruple 2-input positive-NOR gate manufactured by Texas Instruments in the F logic series. It operates within a supply voltage range of 4.5 V to 5.5 V and features an SOIC-14 surface-mount package. The device provides a low-level output current of 20 mA and a high-level output current of -1 mA. Propagation delays are specified at 6.5 ns maximum for low-to-high transitions and 5.3 ns maximum for high-to-low transitions under standard load conditions.

Feature Summary

• Contains four independent 2-input NOR gates performing Boolean functions Y = A + B or Y = A • B in positive logic
• Provides push-pull outputs with high drive capability suitable for interfacing with TTL loads
• Operates within a commercial temperature range from 0°C to 70°C

Applications

• Boolean logic implementation in digital circuits
• Signal gating and control logic
• Data routing and selection networks

Procurement Notes

Verify the active status of the SN74F02DR, as the non-reel variant (SN74F02D) is listed as obsolete. Confirm RoHS compliance and lead finish specifications (NIPDAU) against project requirements. Ensure the SOIC-14 package dimensions align with the PCB footprint design. Check for any specific environmental certifications required for the application environment.

Selection Notes

Select this component when a quad 2-input NOR function is required in the F logic family. Consider the propagation delay characteristics and output drive strength relative to circuit timing constraints. Verify that the operating temperature range meets the system's thermal requirements. Compare against other logic families if lower power consumption or wider voltage ranges are necessary.

Part Context

The SN74F02 belongs to the SN54/74F series of high-speed TTL logic devices. The 'SN74' prefix indicates commercial grade operation, while the 'F' suffix denotes the Fast Schottky technology. This series is designed for applications requiring faster switching speeds compared to standard TTL, utilizing Schottky clamping diodes to prevent saturation and reduce storage time.

Replacement Considerations

SN74F02DRG4 is a qualified replacement part number for the SN74F02DR.
