description

These octal buffers/drivers are designed specifically to improveboth the performance and density of 3-state memory address drivers,clock drivers, and bus-oriented receivers and transmitters. Whenthese devices are used with the ´ALS241, ´AS241A,´ALS244, and ´AS244A, the circuit designer has a choice ofselected combinations of inverting and noninverting outputs,symmetrical active-low output-enable (OE\) inputs, and complementaryOE and inputs. Thesedevices feature high fan-out and improved fan-in.

The -1 version of SN74ALS240A is identical to the standardversion, except that the recommended maximum I_OL for the-1 version is 48 mA. There is no -1 version of the SN54ALS240A.

The SN54ALS240A and SN54AS240A are characterized for operationover the full military temperature range of -55°C to 125°C.The SN74ALS240A and SN74AS240A are characterized for operation from0°C to 70°C.
