SN74LS31 (ACTIVE) Hex Delay Elements for Generating Delay Lines

Hex Delay Elements for Generating Delay Lines - SN74LS31
Datasheet
 

Description

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 IIL 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 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.
