SN74LS21D Overview
Due to its 14-SOIC (0.154, 3.90mm Width) packaging, the part is convenient for international shipping. High reliability is provided by advanced packaging method Tube. AND Gate logic is the basis of its operation. A voltage of 4.75V~5.25V is required for the part to function properly. Temperatures around 0°C~70°C are extended for operation. Surface Mount is the mounting position of the part. In the low and high states of output current, the current is 400μA 8mA. It comes from the 74LS series. In total, there have been 14 terminations. 2 functions in the part enhance the user experience significantly. It is part of the LS family of chips. Trying searching with 74LS21 will yield device variants. A total of 14 pins are injected into the body of the part. This logic device is widely used in a wide variety of applications because it is Surface Mount mounted. To find out what the 14 pins do, please refer to the datasheets. Inputs are limited to 4. The part has 2.2mA current flowing through it in the quiescent state. The logic device is a typical Gates. This part requires 5V power supplies, according to its datasheet. Current output of the device is rated at 8mA. This device includes 1 outputs. Typical operating voltages for the chip are specified as being z volts when it is first manufactured. As a result of the part's 2 channels, it provides a high quality logic output.
