SN74LS247 BCD 到 7 段解码器/驱动器
The '246 and '247 are electrically and functionally identical to the SN5446A/SN7446A, and SN5447A/SN7447A respectively, and have the same pin assignments as their equivalents. The 'LS247 and 'LS248 are electrically and functionally identical to the SN54LS47/SN74LS47 and SN54LS48/SN74LS48, respectively, and have the same pin assignments as their equivalents. They can be used interchangeably in present or future designs to offer designers a choice between two indicator fonts. The '46A, '47A, 'LS47, and 'LS48 compose the 6 and 9 the without tails and the '246, '247, 'LS247, and 'LS248 compose the and the with tails. Composition of all other characters, including display patterns for BCD inputs above nine, is identical.
