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 part is ROHS3 compliant and carries an active lifecycle status — no end-of-life risk for new designs or production BOMs.
11 ns propagation delay — timing margin on a 5 V bus
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
Supply range is 4.5 V to 5.5 V. Input logic-low threshold is 0.8 V; logic-high is 2 V.
Sourcing and lifecycle
The SN74ALS00ADR is listed as Active with no last-time-buy or NRND flags. ROHS3 compliance is confirmed. The part is available through independent distribution and is sourced to order against an RFQ.
