Product Information

Features

  • Package Options Include Plastic "Small Outline" Packages, Ceramic Chip Carriers and Flat Packages, and Plastic and Ceramic DIPs
  • Dependable Texas Instruments Quality and Reliability

Description

The ’279 offers 4 basic S\-R\ flip-flop latches in one 16-pin, 300-mil package. Under conventional operation, the S\-R\ inputs are normally held high. When the S\ input is pulsed low, the Q output will be set high. When R\ is pulsed low, the Q output will be reset low. Normally, the S\-R\ inputs should not be taken low simultaneously. The Q output will be unpredictable in this condition.
