Description
The device has internal logic circuitry, which prevents shoot-through during output state changes. The logic inputs are protected against voltage spikes up to +14V, regardless of V+ voltage. Propagation delay time is minimized and matched between the inverting and noninverting inputs. The device has very fast switching times combined with very short propagation delays (8ns typ) making it ideal for high-frequency circuits.
The device operates from a +4V to +14V single power supply, typically consuming 0.5mA of supply current and has TTL input logic levels. This device is available in a 6-pin SOT23 package and provides an upgrade path for users of the MAX5048B.
