Products Detail

SN74LS21DG4 Overview

It is widely used in a variety of applications due to its Surface Mount mounting. To find out what the 14 pins do, please refer to the datasheets. As of 4, the part supports 4 inputs. 2 circuits are used in this device. Current output of the device is rated at 8 mA. As part of the device, there are 1 outputs. It is specified in the operating instructions of the chip that the operating voltage will be 5 V volts. An operation based on gates of 2. When the device is operating in a temperature environment higher than that of 70 °C, it should be turned off. It is estimated that the minimal operating temperature of the part is 0 °C. It is recommended that users do not supply the device with voltages greater than 5.25 V under normalcircumstances. The lowest voltage the part should receive is 4.75 V. This part performs better with 4 input lines. It can conduct 2-bit signals.
