CD74HC299EE4 Product Details

CD74HC299EE4 Overview


Embedded in a package of type PDIP, the device is available for use. It sums up to 20 where the chip's terminations add up. The Rail/Tube case contains it. Parts with a 4.5V operating supply voltage are specified. Devices with 20 pins are available. As a general recommendation, mounting by Through Hole is recommended. Electronic components fall under the category of HC/UH. A range of 5V is noted as the operating supply voltage of this chip. Additional aspects of this section are as follows: COMMON I/O PINS; GATED OUTPUT CONTROL. This device has 10 input lines available. It has 8 bits in total. This board has 20 pins in total. Under 125°C, it is recommended that it be used. It should not be less than -55°C when operating this device. We use this supply voltage under 6V. It is used at a higher voltage than 2V. A quiescent current of 8μA is used. This device consists of 1 circuits in total.
