The designer has a choice of selected combinations of inverting and noninverting outputs, symmetrical G (active-low output control) inputs, and complementary G and G inputs. 1 2Y4 1A1 1G VCC 2G/2G * 2G for 'ALS762, 'AS762 and 2G 'ALS763, 'AS763 The - 1 versions of the SN74ALS' parts are identical to their standard versions except that the recommended maximum IOL is increased to 48-mA. There are no - 1 versions of the SN54ALS' parts. The SN54' family is characterized for operation over the full military temperature range of - 55C to 125C. The SN74' family is characterized for operation from 0C to 70C.
