That means the output can only sink current (64 mA max per the entry) and cannot source it — the pull-up resistor is external. The 12.5 ns propagation delay at 5 V and 50 pF load puts it in the middle of the 74F speed band — fast enough for most 5 V logic paths but not the fastest option if you are pushing 50+ MHz clock trees. Housed in a 14-SOIC package with a 5.30 mm body width and the supplier device package designated 14-SO. The 1.27 mm pitch is standard SOIC — no fine-pitch surprises. Surface-mount only. No official second-source cross-reference is published, but the 74F family is mature and widely second-sourced through multiple vendors — a BOM hedge is feasible if supply tightens.","metaTitle":"SN74F38NSR 74F Quad 2-Input NAND Gate, Open Collector","metaDescription":"Texas Instruments SN74F38NSR quad 2-input NAND gate with open-collector outputs. 64 mA sink, 12.5 ns delay, 4.5-5.5 V supply.

The SN74F00DR can both source and sink current and offers a faster 5 ns propagation delay at 5 V, 50 pF (vs 12.5 ns for the SN74F38NSR). The open-collector version trades speed for the ability to wire outputs together or drive loads that require an external pull-up."},{"question":"What compliance documentation does TI provide for SN74F38NSR?","answer":"The part is ROHS3 Compliant.
