☆型号:DDSCR-R84H 可编程控制器 (PLC) 内存模块 实现高效的产品组装
【产品详情】
SN74HC148D是8到3优先级编码器,具有对输入的优先级解码的功能,以确保仅对最高位的数据线进行编码。它将八条数据线编码为3行(4-2-1)二进制(八进制)。提供了级联电路(使能输入EI和使能输出EO),以允许八进制扩展,而无需外部电路。数据输入和输出在低逻辑电平下处于活动状态。
输出可驱动多达10个LSTTL负载
80?A最大低功耗
16ns典型tpd
5V时±4mA输出驱动
1?A最大低输入电流
绿色产品,无Sb/Br

【英文介绍】
The SN74HC148D is an 8 to 3 priority encoder with the ability to decode the priority of the input to ensure that only the highest bit data line is encoded. It encodes eight data lines into three (4-2-1) binary (octal) lines. A cascade circuit (enable input EI and enable output EO) is provided to allow octal expansion without the need for an external circuit. Data input and output are active at low logic levels.
The output can drive up to 10 LSTTL loads
80? A Maximum Low power consumption
16ns Typical tpd
5V ±4mA output drive
1? A Maximum low input current
Green products, no Sb/Br
