It operates from a 4.75 V to 5.25 V supply and is specified over the commercial temperature range of 0°C to 70°C. The 15 ns maximum propagation delay at 5 V with a 15 pF load sets the timing budget for bus interfacing and control logic in 5 V legacy systems. ## Output drive — 400 µA source, 8 mA sink The output can source 400 µA and sink 8 mA. That is typical for the LS family — enough to drive a few standard LS inputs or one 74F load, but not enough for a relay coil, LED directly, or a long backplane trace without a buffer. Plan on a fan-out of about 10 LS loads per output. ## Logic thresholds — 0.8 V low, 2 V high Input logic levels are 0.8 V for low and 2 V for high, which is the standard 74LS threshold. This is compatible with TTL outputs and most 5 V CMOS logic that swings rail-to-rail, but the 2 V high threshold means a 3.3 V CMOS output driving this input may not reach a valid high without a pull-up to 5 V. ## Active lifecycle — no EOL watch needed now The SN74LS00PSR carries an Active product status and is ROHS3 compliant. ## Package — 8-SOIC wide-body, 5.30 mm width The part comes in an 8-SOIC package with a 0.209-inch (5.30 mm) body width, and the supplier device package is listed as 8-SO. This is the wide-body SOIC footprint, not the narrow 3.90 mm SOIC-8. The reel options are Tape & Reel (TR) and Cut Tape (CT), so it fits standard pick-and-place lines.","metaTitle":"SN74LS00PSR 74LS NAND Gate, 2-Input, 8-SOIC, 15ns","metaDescription":"TI SN74LS00PSR dual 2-input NAND gate, 74LS family, 15ns @ 5V/15pF, 4.75-5.25V supply, 0-70°C, 8-SOIC.
