SN74LS21DR Overview


The part is convenient to ship overseas because it is packed in a 14-SOIC (0.154, 3.90mm Width). High reliability is provided by advanced packaging method Tape & Reel (TR). Based on the AND Gate logic principle, it works. Ensure the part's full functionality by setting the voltage to 4.75V~5.25V. Temperatures around 0°C~70°C are extended for operation. The part is mounted in Surface Mount. In both high and low states, output current is 400μA 8mA. The number 74LS refers to it. Totally, there are 14 terminations. In addition to 2 functions that significantly boost the user experience, the part includes 2 other features. LS is a chip that is part of this device. Trying searching with 74LS21 will yield device variants. It is injected into the part body with 14 pins. Many applications use this logic device with Surface Mount mounting. Datasheets for 14 pin functions are available upon request. 4 inputs are supported by the part. The logic device is a typical Gates. A method of industry TR is included in the package. It is specified in the datasheet that the part requires It is specified in the datasheet that the part requires 5V power supplies. power supplies. Current output of the device is rated at 8mA. The device has 1 outputs. The operation uses 2 elements in total. Typical operating voltages for the chip are specified as being z volts when it is first manufactured.
