CD4028B中文资料CMOS BCD 转十进制或二进制转八进制解码器/驱动器数据手册TI规格书

描述 Description

CD4028 types are BCD-to-decimal or binary-to-octal decoders consisting of buffering on all 4 inputs, decoding-logic gates, and 10 output buffers. A BCD code applied to the four input, A to D, results in a high level at the selected one of 10 decimal decoded outputs. Similarly, a 3-bit binary code applied to inputs A through C is decoded in octal code at output 0 to 7 if D = \"0\". High drive capability is provided at all outputs to enhance dc and dynamic performance in high fan-out applications.

The CD4028B-Series types are supplied in 16-lead hermetic dual-in-line ceramic packages (F3A suffix), 16-lead dual-in-line plastic packages (E suffix), 16-lead small-outline packages (M, M96, MT and NSR suffixes), and 16-lead thin shrink small-outline packages (PW and PWR suffixes).

特性 Features

• BCD-to-decimal decoding or binary-to-octal decoding
• \"Positive logic\" inputs and outputs……decoded outputs go high on selection
• Standardized, symmetrical output characteristics
• Maximum input current of 1 µA at 18 V over full package-temperature range; 100 nA at 18 V and 25°C
• 5-V, 10-V, and 15-V parametric ratings
• Applications:
• Indicator-tube decoder
• Address decoding-memory selection control

简介

CD4028B属于集成电路（IC）的信号开关多路复用器解码器。由TI制造生产的CD4028B信号开关，多路复用器，解码器逻辑型信号开关、多路复用器和编码器 IC 可用于对以数字格式表示数据的电信号进行路由和选择。这些器件与设计用于模拟信号的类似产品有所不同，它们保留的信息表示为两个电状态之一，而不是两个外部界限内的无穷变化量。
