Texas Instruments 74LVC series, NOR Gate, 1 Circuit, 3 Inputs, 32mA output, 1.65V to 5.5V supply, -40°C to 125°C, 6-XFDFN package, SN74LVC1G27DSFR.
| Parameter | Value |
|---|---|
| Series | 74LVC |
| Logic type | NOR Gate |
| Mounting | Surface Mount |
| Supply voltage | 1.65V ~ 5.5V |
| Current - quiescent | 10 µA |
| Current - output high, low | 32mA, 32mA |
| I/O channels | 3 |
| Operating temperature | -40°C~125°C |
| Package | Tape & Reel (TR); Cut Tape (CT) |
| Case | 6-XFDFN |
| Number of circuits | 1 |
| Input logic level - low | 0.7V ~ 0.8V |
| Input logic level - high | 1.7V ~ 2V |
| Max propagation delay @ v, max CL | 3.6ns @ 5V, 50pF |
Propagation delay is 3.6ns at 5V with a 50pF load, fast enough for most glue-logic timing closure up to 50 MHz.
Quiescent current is a maximum of 10 µA, so the part adds negligible standby power in battery-operated equipment.
Both parts are the same single 3-input NOR gate from the 74LVC family. The difference is the package: the DSFR variant is in a 6-XFDFN (6-SON 1x1 mm), while the DCKR variant uses a different package. If the PCB footprint matches the 6-SON, the DSFR is a functional drop-in replacement. Verify the land pattern before ordering.
