These LS31 delay elements are intended to provide well-defined delays across both temperature and VCC ranges. Used in cascade, a limitless range of delay gating is possible. All inputs are PNP with IL MAX of -0.2 mA. Gates 1, 2, 5, and 6 have standard Low-Power Schottky output sink current capability of 4 and 8 mA IOL Buffers 3 and 4 are rated at 12 and 24 mA. The 74LS31 is characterized for operation from 0°C to 70°C
Features :-
- Delay Elements for Generating Delay Lines
- Inverting and Non-inverting Elements
- Buffer NAND Elements Rated at JOL of 12/24 mA
- PNP Inputs Reduce Fan-In (IIL=-0.2 mA MAX)
