Product details

The SN74LVC1G02MDCKREP: Single 2-input NOR gate in SC-70-5. Output goes low when either input is high.

The supply range from 1.65V to 5.5V means this single gate can sit on a 1.8V FPGA I/O bank, a 3.3V microcontroller bus, or a 5V legacy peripheral interface without a level translator. The input logic thresholds scale with VCC — low at 0.7V to 0.8V, high at 1.7V to 2V — so it reliably interprets signals from both low-voltage and 5V domains. Output drive is 32mA for both high and low states, enough to drive a downstream gate input or a small LED indicator directly.

5 ns propagation delay — fast enough for most glue logic, not a race-condition fixer

Maximum propagation delay 5 ns at 5V with 50 pF load.

Frequently asked questions

What is the function of SN74LVC1G02MDCKREP?

It is a single 2-input NOR gate. The output goes low when either input is high, and goes high only when both inputs are low. Use it for combinatorial logic, signal gating, or as a universal gate to build any other logic function with multiple devices.

Is SN74LVC1G02MDCKREP obsolete or active?

The part is listed as active.

Does SN74LVC1G02MDCKREP have a direct equivalent from another brand?

Several manufacturers offer pin-compatible single 2-input NOR gates in the SC-70-5 package, such as NXP's 74LVC1G02GW or ON Semiconductor's NL27WZ02.

Is SN74LVC1G02MDCKREP RoHS compliant?

Yes, it is ROHS3 compliant, meaning it meets the EU RoHS directive with no exemptions for lead, mercury, cadmium, or other restricted substances.
