With a 2 V high-level input threshold and 0.8 V low-level threshold, the device accepts standard TTL levels directly — no level translation needed when driving from a 5 V TTL output. Output drive is asymmetric: 400 µA source, 8 mA sink. The 8 mA low-level drive handles a fan-out of 10 standard LS loads; the 400 µA high-level drive limits the pull-up fan-out to about 5 loads. For heavily loaded buses, buffer the output or use a higher-drive family like 74ALS with a larger output stage. ## Active production and compliance documentation The device is supplied in tube packaging. The 14-SOIC footprint (0.154\" body width, 3.90 mm) is a standard JEDEC MS-012 variant — the same land pattern used by the 74AHCT and 74HCS series in SOIC-14, so a board laid out for those families accepts this part without a footprint change. ## How the SN74ALS00AD compares to the SN74AHCT132DR The AHCT132 includes Schmitt-trigger inputs with hysteresis (0.5 V to 0.6 V low threshold, 1.9 V to 2.1 V high threshold) versus the ALS00's fixed TTL thresholds (0.8 V low, 2 V high). Propagation delay is similar: 9 ns for the AHCT132 versus 11 ns for the ALS00 at 5 V, 50 pF. The AHCT132's Schmitt-trigger inputs reject slow edges and noise on the input lines — a meaningful advantage in noisy backplane or cable-drive applications where the ALS00's standard inputs may double-clock on a slow rise time.","metaTitle":"SN74ALS00AD Texas Instruments 74ALS Quad NAND Gate, 14-SOIC","metaDescription":"SN74ALS00AD Texas Instruments 74ALS quad 2-input NAND gate in 14-SOIC.

The key difference is that the AHCT132 includes Schmitt-trigger inputs with hysteresis, which improves noise immunity on slow or noisy input edges. Both operate from a 5 V supply and have similar propagation delays."},{"question":"Will the SN74ALS00AD drop into a board laid out for the SN74AHCT132DR?","answer":"Yes, both devices use the same 14-SOIC footprint (0.154\" body width, 3.90 mm). The pinout is identical for a quad 2-input NAND gate. No board respin is required for the footprint, but verify the input threshold levels — the ALS00 uses standard TTL thresholds (0.8 V low, 2 V high) while the AHCT132 uses Schmitt-trigger thresholds with hysteresis."},{"question":"What compliance documentation does Texas Instruments provide for the SN74ALS00AD?","answer":"Texas Instruments provides ROHS3 compliance documentation for the SN74ALS00AD.
