ordering information These octal buffers/drivers are designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. When these devices are used with the ’ALS241, ’AS241A, ’ALS244, and ’AS244A devices, the circuit designer has a choice of selected combinations of.
that the recommended maximum IOL for the -1 version is 48 mA. There is no -1 version of the SN54ALS240A.
