SN74LS273DWG4 Product Details

SN74LS273DWG4 Overview


It is packaged in the way of SOIC. The output it is configured with uses TTL. D latch consists of 1 elements. There are 20 terminations, which are the practice of ending a transmission line with a device that matches the characteristic impedance of the line. It is powered from a supply voltage of 5V. This D flip flop belongs to the family of LS. This electronic part is mounted in the way of Surface Mount. It is designed with 20 pins. Edge triggering is a type of triggering that allows a circuit to become active at the positive edge or the negative edge of the clock signal. The clock edge trigger type of this device is Positive Edge. This part is included in FF/Latches. It operates from 5V power supplies. The supply voltage should be maintained at 5V for high efficiency. The high level output current is set to -400μA. The low level output current is set to 8mA. The operating temperature should be lower than 70°C. The operating temperature should be higher than 0°C. It operates with the minimal supply voltage of 4.75V. It supports the maximal supply voltage of 5.25V. The frequency that can be achieved is 40MHz. The logic IC it adopts is D FLIP-FLOP. It is equipped with 1 Functions . It is equipped with 20 pin count. The output current of 8mA makes it feature maximum design flexibility.
