Descriptions:

The SN74LS279N is a quad S-R (Set-Reset) latch with active-low inputs. It features four independent latches, each with two set inputs (S) and one reset input (R). The outputs remain stable when both inputs are inactive (high).

Features:

  • Quad S-R Latches: Four independent latches in a single package.
  • Active-Low Inputs: Set and Reset inputs are active-low.
  • Schottky Clamped: Improves switching speed.
  • Wide Operating Voltage: Compatible with standard TTL levels.
  • Standard Output Drive: Suitable for driving TTL loads.
  • High Noise Immunity: Typical of LS-TTL logic family.

This information is based on the manufacturer's datasheet.
