SN74LS279AN

产品概述

The SN74LS279AN is a 4 basic S-R Flip-flop Latch. 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.

• 7V Input voltage
• 2V High-level input voltage
• 0.8V Low-level input voltage
• 8mA Low-level output current
• 20ns Low pulse duration
