Product details

Quad 2-input NAND gate in 14-SOIC — what this part is

The Texas Instruments SN74ALS00ADR is a quad 2-input NAND gate from the 74ALS logic family, packaged in a 14-SOIC (0.154", 3.90 mm width) surface-mount package. It operates from a 4.5 V to 5.5 V supply and is rated for the commercial temperature range of 0°C to 70°C.

The 11 ns max propagation delay at 5 V and 50 pF load sets the timing budget for address decoding, control signal gating, or clock distribution in a 5 V TTL system.

Output drive: 400 µA source, 8 mA sink

The output can source 400 µA and sink 8 mA.

Supply and logic thresholds

Input logic-low threshold is 0.8 V; logic-high is 2 V.

ROHS3 compliance is confirmed.

Frequently asked questions

Is SN74ALS00ADR RoHS compliant?

Yes, it is ROHS3 compliant — no exemptions apply. Suitable for EU-market and medical/consumer applications requiring lead-free solder.

Can SN74ALS00ADR replace 74LS00?

The SN74ALS00ADR is pin-compatible with the 74LS00 in the same 14-SOIC footprint and uses the same 5 V supply. The ALS family offers lower propagation delay (11 ns vs roughly 15 ns for LS) and lower power per gate. Functionally it is a drop-in replacement, but verify the input threshold compatibility — ALS thresholds are the same 0.8 V / 2 V as LS, so it works.
