74LS31 Hex Delay Line Generator IC (7431) DIP-16 Package

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
