The designer has a choice of selected combinations of inverting and noninverting outputs, symmetrical active-low output-enable (OE) inputs, and complementary OE and OE inputs. These devices feature high fan-out and improved fan-in. The -1 version of SN74ALS241C is identical to the standard version, except that the recommended maximum IOL of the -1 version is 48 mA. There is no -1 version of the SN54ALS241C. The SN54ALS241C and SN54AS241A are characterized for operation over the full military temperature range of − 55 °C to 125°C. The SN74ALS241C and SN74AS241A are characterized for operation from 0 °C to 70°C.
