| NTE2032 Integrated Circuit BCD-to-Seven-Segment Decoder Driver Description: The NTE2032 is a monolithic integrated circuit in a 16-Lead DIP type package that performs the BCD-to-seven-segment decoding function and features constant-current segment drivers. When used with the NTE2054 A/D converter, the NTE2032 provides a complete digital readout system with a minimum number of external parts. Features: D TTL Compatible Input Logic Levels D 25mA (Typ) Constant Current Segment Outputs D Eliminates Need for Output Current Limiting Resistors D Pin Compatible with Other Industry Standard Decoders D Low Standby Power Dissipation: 18mW Typ Absolute Maximum Ratings: DC Supply Voltage (Between Pin1 and Pin10), V+ . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7V Input Voltage (Pin1, Pin2, Pin6, and Pin7), VIN . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5.5V Output Voltage, VO Output "OFF" . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7V Output "ON" (Note 1) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 10V Device Dissipation (TA +55C), PD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1W Derate Above 55C . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 10.5mW/C Operating Ambient Temperature Range, Topr . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0 to +75C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -65 to +150C Lead Temperature (During Soldering, 1.16" 1/32" (1.59mm 0.79mm), 10sec max), TL . . +265C Note 1.
