Product Overview
SN74LS00 is a Texas Instruments quad 2-input NAND gate in the Logic category. Each gate implements Y = A·B inverted, with the positive-logic equivalent Y = A + B. The device provides 4 independent NAND gates, each with 2 inputs.
The SN74LS00 operates from a recommended 4.75 V to 5.25 V supply, with 5 V nominal. Input thresholds are TTL-compatible, with VIH at 2 V minimum and VIL at 0.8 V maximum. Input pins accept 3.3 V or 2.5 V logic inputs.
Package options include SSOP-14 DB (6.20 mm x 5.30 mm), SOIC-14 D (8.65 mm x 3.91 mm), PDIP-14 N (19.30 mm x 6.35 mm), SO-14 NS (10.30 mm x 5.30 mm), and SO-8 PS (6.20 mm x 5.30 mm). For 14-pin packages, VCC is pin 14 and GND is pin 7.

Procurement Notes
When requesting a quote for SN74LS00, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For MCU, processor and logic IC sourcing, package, operating voltage, temperature grade, speed or frequency grade, firmware or mask version, lifecycle status and programming requirements should be checked before approval.
