SN74ALS244C-1 具有三态输出的八路缓冲存储器/线路驱动器
SN74ALS244C-1 描述
These octal buffers and line drivers are designed specifically to improve the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. With the ´ALS240A, ´ALS241C, ´AS240A, and ´AS241A, these devices provide the choice of selected combinations of inverting outputs, symmetrical active-low output-enable (
) inputs, and complementary OE and inputs.
The -1 version of SN74ALS244C is identical to the standard version, except that the recommended maximum IOL for the -1 version is 48 mA. There is no -1 version of the SN54ALS244C.
The SN54ALS244C and SN54AS244A are characterized for operation over the full military temperature range of -55°C to 125°C
