M74HC148 8 to 3 Line Priority Encoder

The M74HC148 is an high speed CMOS 8 TO 3 LINE PRIORITY ENCODER fabricated with silicon gate C2MOS technology.

The M74HC148 encodes eight data lines to three-line (4-2-1) binary (octal). Cascading circuitry (enable input EI and enable output EO) has been provided to allow octal expansion without the need for external circuitry. Data inputs are active at the low logic level.

All inputs are equipped with protection circuits against static discharge and transient excess voltage

技术特性

  • ICC = 4µA(MAX.) at TA=25 °C
• HIGH NOISE IMMUNITY:
  • VNIH = VNIL = 28 % VCC (MIN.)
• SYMMETRICAL OUTPUT IMPEDANCE:
  • |IOH| = IOL = 4mA (MIN)
• BALANCED PROPAGATION DELAYS:
  • tPLH tPHL
• WIDE OPERATING VOLTAGE RANGE:
  • VCC (OPR) = 2V to 6V
• PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 148
