This document describes the National Semiconductor 5425/DM7425, a device containing two 4-input gates that perform the logic NOR function. The output of each gate is gated (strobed) by pin 3 and pin 11 using positive true logic.
The datasheet provides absolute maximum ratings, recommended operating conditions, and electrical characteristics over the recommended operating free air temperature range. It also includes switching characteristics for propagation delay times.
| Free Air Operating Temperature (5425) | -65°C to +125°C |
|---|---|
| High Level Input Voltage (Vih) | 2V |
| Low Level Input Voltage (Vil) | 0.8V |
| Low Level Output Current (Iol) | 16 mA |
| Propagation Delay Time High to Low (tPHL) | 15 ns |
