Product Summary

The NTE74LS348 is an 8-line to 3-line priority encoder in a 16-lead plastic DIP-type package that features priority decoding of the inputs to ensure that only the highest-order data line is encoded. This device encodes eight data lines to three-line (4-2-1) binary (octal). Cascading circuitry (enable input E1 and enable output EO) has been provided to allow octal expansion. Outputs A0, A1 and A2 are implemented in three-state logic for easy expansion up to 64 lines without the need for external circuitry.

Data Sheet

  • Three−state outputs drive bus lines directly
  • Encodes 8 data lines to 3−line binary (octal)
  • Data delay: 15ns (Typ)
  • Power dissipation: 60mW (Typ)
  • Applications: N-bit encoding, code converters and generators
  • Absolute maximum ratings:
  • Supply voltage VCC: 7V
  • DC input voltage VIN: 7V
  • 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
