SN74HC148D .

产品概述

The SN74HC148D is a 8-to-3 Priority Encoder features priority decoding of the inputs to ensure that only the highest-order data line is encoded. It encodes eight data lines to 3-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 and outputs are active at the low logic level.

  • Outputs can drive up to 10 LSTTL loads
  • 80µA Maximum low power consumption
  • 16ns Typical tpd
  • ±4mA Output drive at 5V
  • 1µA Maximum low input current
  • Green product and no Sb/Br
