Introduction

AI Translation

The NTE7447 is a BCD-to-seven-segment decoder/driver in a 16-pin plastic DIP package with active-low outputs for direct drive of common-anode VLED or incandescent lamp indicators. The device features full ripple-blanking input/output control and a lamp test input. For BCD input counts greater than 9, unique display patterns are shown to verify input conditions. The NTE7447 incorporates automatic leading and/or trailing edge zero-blanking control (RBI and RBO). Lamp test (LT) can be performed at any time when the BI/RBO node is set high. The device also includes a priority blanking input (BI) for pulse-controlled lamp brightness or output suppression. Inputs and outputs are fully compatible with TTL logic outputs.
