Product Summary

The NTE74249 is a BCD-to-Seven-Segment Decoder/Driver in a 16-lead plastic DIP-type package incorporating automatic leading and/or trailing-edge zero-blanking control (RBI and RBO). Lamp test (LT) may be performed at any time when the BI/RBO node is at a high level. This device also contains an overriding blanking input (BI) which can be used to control the lamp intensity by pulsing or to inhibit the outputs. Inputs and outputs are entirely compatible for use with TTL logic outputs.

Data Sheet

Features:

  • Open collector outputs
  • Lamp test provision
  • Leading/trailing zero suppression
    • Absolute maximum ratings:
    • Supply voltage VCC: 7V
    • Input voltage VIN: 5.5V
    • Current forced into any output in the off−state: 1mA
    • Operating temperature range TA: 0°C to +70°C
    • Storage temperature range Tstg: −65°C to +150°C
    • Unless otherwise specified, all voltages are referenced to GND
