The NTE74LS168A (BCD decade) and NTE74LS169A (4−bit binary) are fully synchronous 4−stage up/down counters in a 16−Lead plastic DIP-type package featuring a preset capability for programmable operation, carry look ahead for easy cascading and a U/D input to control the direction of counting. The NTE74LS168A counts in a BCD decade (8, 4, 2, 1) sequence while the NTE74LS169A operates in a Modulo 16 binary sequence. All state changes, whether in counting or parallel loading, are initiated by the LOW−to−HIGH transition of the clock.
  • Low-power dissipation: 100mW (Typ)
  • High−speed count frequency: 30MHz (Typ)
  • Fully synchronous operation
  • Full carry look ahead for easy cascading
  • Single up/down control input
  • Positive-edge trigger operation
  • Input clamp diodes limit high−speed termination effects
  • Absolute maximum ratings:
    VCC: 7V
  • VIN: 7V
  • TA: 0°C to +70°C
  • Tstg: −65°C to +150°C
  • Unless otherwise specified, all voltages are referenced to GND
