Product details

Quad 2-input NOR gate for 5V TTL logic

The SN74LS02DR is a quad 2-input NOR gate from the 74LS series. Each of the four independent gates performs the NOR function on two inputs, with a propagation delay of 15 ns at 5V and 15 pF load. The supply range is 4.75V to 5.25V. Output drive is rated at 400 µA sourcing and 16 mA sinking. The operating temperature range is 0°C to 70°C.

Active production, ROHS3 compliant

The SN74LS02DR carries an Active lifecycle status and is ROHS3 compliant. No last-time-buy or end-of-life notice is on record. For a BOM freeze or a long-production-run line, this part is a safe choice. The 14-SOIC package is a standard footprint shared across many 74LS and 74HC logic gates.

Frequently asked questions

What is the price of SN74LS02DR?

Pricing is confirmed at quote time against an RFQ. No public price is listed; request a quote for the current market rate.

Is SN74LS02DR available via RFQ confirmation?

Availability is confirmed at quote time. Submit an RFQ to check current stock levels through our sourcing network.

What are the specifications of SN74LS02DR?

Key specs: 4.75V to 5.25V supply, 15 ns propagation delay at 5V and 15 pF, 400 µA / 16 mA output drive, 0°C to 70°C operating range, 14-SOIC package.

Is SN74LS02DR ROHS compliant?

Yes, the SN74LS02DR is ROHS3 compliant.

Does SN74LS02DR replace SN74LS02N?

The SN74LS02DR is the surface-mount 14-SOIC variant of the same die as the SN74LS02N (through-hole DIP). Functionally identical — same logic, same timing, same supply range. The DR suffix replaces the N suffix for surface-mount assembly.
