These devices implement three generalized functions as outlined below. First: They accept a single-ended, low-current digital input of either polarity and process it to activate a pair of high-current, totem pole outputs which can source or sink up to 1.5A each. Second: They provide an optional single-ended to push-pull conversion through the use of an internal flip-flop driven by double-pulsesuppression logic. With the flip-flop disabled, the outputs work in parallel for 3.0A capability. Third: Protection functions are also included for pulse-by-pulse current limiting, automatic deadband control, and thermal shutdown. These devices are available in a two-watt plastic “bat-wing” DIP for operation over a 0°C to 70°C temperature range and, with reduced power, in a hermetically sealed cerdip for -55°C to +125°C operation. Also available in surface mount Q and L packages. TRUTH TABLE INV H L H L N.I H H L L OUT L H L L OUT = INV and N.I. OUT = INV or N.I.
