INTEGRATED CIRCUITS DATA SHEET For a complete data sheet, please also download: • The IC04 LOCMOS HE4000B Logic Family Specifications HEF, HEC • The IC04 LOCMOS HE4000B Logic Package Outlines/Information HEF, HEC HEF4019B MSI Quadruple 2-input multiplexer Product specification File under Integrated Circuits, IC04 January 1995 Philips Semiconductors Product specification Quadruple 2-input multiplexer DESCRIPTION The HEF4019B provides four multiplexing circuits with common select inputs (SA, SB); each circuit contains two inputs (An, Bn) and one output (On). It may be used to select four bits of information from one of two sources. HEF4019B MSI The A inputs are selected when SA is HIGH, the B inputs when SB is HIGH. When SA and SB are HIGH, output (On) is the logical OR of the An and Bn inputs (On = An + Bn). When SA and SB are LOW, output (On) is LOW independent of the multiplexer inputs.

1. 物料型号: - 型号为HEF4019B,这是一个四重2输入多路选择器。

2. 器件简介: - HEF4019B提供四个多路选择电路,具有共同的选择输入(SA, SB);每个电路包含两个输入(An, Bn)和一个输出(On)。它可以用来从两个源中选择四比特的信息。当SA为高电平时选择A输入,当SB为高电平时选择B输入。当SA和SB都为高时,输出On是An和Bn输入的逻辑或(On=An+Bn)。当SA和SB都为低时,输出On不受多路选择器输入影响,为低电平。

3. 引脚分配: - SA, SB为选择输入(高电平有效)。 - A0到A3为多路选择器输入。 - B0到B3为多路选择器输入。 - O0到O3为多路选择器输出。

4. 参数特性: - 电源电压范围:5V、10V、15V。 - 典型传播延迟:An, Bn, SA, SB到On的高到低传播延迟为5ns到145ns,低到高传播延迟为60ns到130ns。 - 输出转换时间:高到低为60ns到120ns,低到高为60ns到120ns。

5. 功能详解: - 功能图和真值表说明了器件的逻辑功能。SA和SB共同决定输出On的状态,根据An和Bn的输入,输出可以是高、低或An和Bn的逻辑或。

6. 应用信息: - HEF4019B的一个应用示例是真值/补码选择。

7. 封装信息: - 提供了三种封装类型:HEF4019BP(N)为16脚DIL塑料封装(SOT38-1),HEF4019BD(F)为16脚DIL陶瓷封装(cerdip,SOT74),HEF4019BT(D)为16脚SO塑料封装(SOT109-1)。
