Description
General part information
SN74LS31 Series
These 'LS31 delay elements are intended to provide well-defined delays across both temperature and VCCranges. Used in cascade, a limitless range of delay gating is possible.
All inputs are PNP with IILMAX 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 SN54LS31 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74LS31 is characterized for operation from 0°C to 70°C.
