The low power Schottky LS TTL Family combines a current and power reduction by a factor of 5 (compared to 7400 TTL) with antisaturation Schottky diode clamping and advanced processing, using shallower diffusions and higher sheet resistivity to achieve circuit performance better than conventional TTL. Available from C.S.I. in standard D.I.P. packages
