Six inverters in a single 14-SOIC — board-level signal conditioning
The SN74ALVC04DR packs six independent inverter gates into a 14-SOIC package, each with a single input and a standard CMOS output. This is the go-to part when a digital signal needs polarity inversion, a clock needs clean buffering, or a sensor output requires logic-level translation across a mixed-voltage backplane. The input thresholds are TTL-compatible: low at 0.7 V to 0.8 V, high at 1.7 V to 2.0 V, so the part interfaces directly with 3.3 V logic without external level shifters.
Propagation delay and output drive — timing closure for 100 MHz paths
Maximum propagation delay is 2.8 ns at 3.3 V with a 50 pF load. This sets the data-rate ceiling: a chain of three inverters adds roughly 8.4 ns of latency, which is acceptable for 100 MHz clock distribution but starts to cut into setup margins above 150 MHz. The 24 mA symmetric output drive (both source and sink) drives standard CMOS loads and short PCB traces up to a few inches without needing a buffer. Quiescent current is 10 µA maximum across the full supply range — negligible in battery-powered sensor nodes or always-on monitoring circuits.
Package and board integration — 14-SOIC reflow profile
The 1.27 mm pin pitch is hand-solderable and reflow-compatible with standard lead-free profiles. The supplier device package is also 14-SOIC, so no footprint mismatch between the order code and the physical part. The ROHS3 compliance (no exemptions) means the part passes EU RoHS and China RoHS without additional documentation overhead.
This is a standard-product logic gate with high-volume demand across industrial, telecom, and consumer markets, so supply continuity is stable.
