74HC540; 74HCT540 Octal buffer/line driver; 3-state; inverting Rev. 3 — 21 January 2013 Product data sheet 1. General description The 74HC540; 74HCT540 is an 8-bit inverting buffer/line driver with 3-state outputs. The device features two output enables (OE1 and OE2). A HIGH on OEn causes the outputs to assume a high-impedance OFF-state. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. 2. Features and benefits  Inverting outputs  Complies with JEDEC standard no. 7A  Input levels:  For 74HC540: CMOS level  For 74HCT540: TTL level  ESD protection:  HBM JESD22-A114F exceeds 2000 V  MM JESD22-A115-A exceeds 200 V  Multiple package options  Specified from 40 C to +85 C and from 40 C to +125 C 3.

物料型号: - 74HC540; 74HCT540

器件简介: - 该器件是一个8位反相缓冲器/线驱动器,具备3态输出功能。设备具有两个输出使能(OE1和OE2),当OEn输入高电平时,输出将呈现高阻态关闭状态。输入包含钳位二极管,允许使用限流电阻将输入接口至超过VCC的电压。

引脚分配: - 引脚配置图显示了DIP20、SO20和SSOP20三种封装的引脚分配。例如,DIP20封装中,Vcc为20脚,GND为10脚,OE1为1脚和19脚(74HC540和74HCT540分别对应),数据输入A0至A7分别对应2至9脚,数据输出Y0至Y7分别对应18至11脚。

参数特性: - 包括供电电压(Vcc)、输入钳位电流、输出钳位电流、输出电流、供电电流、存储温度等。以74HC540为例,供电电压范围为2.0V至6.0V,供电电流最大为70mA。

功能详解: - 功能表显示了控制端OE1和OE2的逻辑状态对输入An和输出Yn的影响。当两个使能端都为低电平时,输出呈现低电平;当至少一个使能端为高电平时,输出呈现高阻态。

应用信息: - 该器件符合JEDEC标准,具有多种封装选项,适用于-40°C至+85°C和-40°C至+125°C的温度范围。

封装信息: - 提供DIP20、SO20、SSOP20等封装类型,每种封装都有详细的尺寸图和参考尺寸。
