ROHS3 compliant per, meaning no RoHS exemption declarations are needed at the receiving end. This is a quad 2-input NAND gate (four independent gates, each with two inputs) but with open-drain outputs instead of the usual totem-pole push-pull stage. The output can only sink current (4 mA rated low-level drive); it cannot source current. A pull-up resistor to VCC is required on each output to create a valid high logic level. The open-drain topology lets multiple gate outputs connect to the same pull-up resistor for wired-OR or shared-bus configurations without contention. This is the main reason to choose this part over a standard 74HCT00 quad NAND. ## Temperature grade and propagation delay This extends the usable ambient envelope for outdoor telecom, engine-bay, or thermal-cycling applications without needing a separate industrial-grade variant. Maximum propagation delay is 24 ns at 4.5 V supply with a 50 pF load. At 5 V the delay is typically shorter, but the 24 ns ceiling is the timing closure number for worst-case conditions across temperature and voltage. For bus cycles above ~20 MHz, this gate will be the timing bottleneck. ## Supply rails and input thresholds Input logic low threshold is 0.8 V max; input logic high is 2 V min. This means the gate accepts 3.3 V logic as a valid high (2 V is below 3.3 V) and 0 V as a valid low, making it usable in mixed-voltage systems without a level translator on the input side, provided the 3.3 V driver's Voh exceeds 2 V. Quiescent current is 2 µA max across temperature — negligible for battery-powered equipment where the gate sits idle between operations. Housed in a 14-SOIC narrow-body package (3.90 mm body width, 0.154\" pitch). The supplier device package is 14-SOIC, surface-mount only. The footprint matches standard SOIC-14 land patterns — no special pad geometry required for the open-drain outputs.","metaTitle":"CD74HCT03MT Texas Instruments Quad NAND Gate, Open Drain","metaDescription":"Active-production quad 2-input NAND gate with open-drain outputs. 4.5-5.5 V supply, -55 to 125°C range. 14-SOIC.
