SN74HC148N .

产品概述

The SN74HC148N is a 8 to 3-line Priority Encoder features priority decoding of the inputs to ensure that only the highest-order data line is encoded. This device encode 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.

• Wide operating voltage range
• Outputs can drive up to 10 LSTTL loads
• Low power consumption
• 16ns Typical TPD
• ±4mA Output drive at 5V
• 1µA Maximum low input current
• Encode 8-data to 3-line binary
