These devices feature inputs and outputs on opposite sides of the package to facilitate printed circuit board layout. The 3-state control gate is a 2-input AND gate with active-low inputs so that, if either output enable (OE1 or OE2) input is high, all eight outputs are in the high-impedance state. Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators in a mixed 3.3-V/5-V system environment. These devices are fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the devices when they are powered down. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. 9.2 Functional Block Diagram OE1 OE2 A1 1 19 2 18 Y1 To Seven Other Channels 9.3 Feature Description • • • Wide operating voltage range – Operates from 1.65 V to 3.6 V Allows down voltage translation – Inputs accept voltages to 5.5 V Ioff feature – Allows voltages on the inputs and outputs when VCC is 0 V 9.4 Device Functional Modes Table 1.

It can produce 24 mA of drive current at 3.3 V. Therefore, this device is ideal for driving multiple outputs and for high-speed applications up to 100 Mhz. The inputs are 5.5 V tolerant allowing the device to translate down to VCC. 10.2 Typical Application Regulated 3.3 V OE1 Vcc OE2 A1 Y1 uC System Logic A8 uC or System Logic Y8 LEDs GND Figure 4. Typical Application Diagram 10.2.1 Design Requirements This device uses CMOS technology and has balanced output drive. Care should be taken to avoid bus contention because it can drive currents that would exceed maximum limits. The high drive will also create fast edges into light loads; therefore, routing and load conditions should be considered to prevent ringing. 10.2.2 Detailed Design Procedure 1. Recommended Input Conditions – Rise time and fall time specs: See (Δt/ΔV) in the Recommended Operating Conditions table. – Specified high and low levels: See (VIH and VIL) in the Recommended Operating Conditions table. – Inputs are overvoltage tolerant allowing them to go as high as 5.5 V at any valid VCC. 2. Recommend Output Conditions – Load currents should not exceed 25 mA per output and 50 mA total for the part. – Outputs should not be pulled above VCC.

ICC vs Frequency 11 Power Supply Recommendations The power supply can be any voltage between the MIN and MAX supply voltage rating located in the Recommended Operating Conditions table. Each VCC pin should have a good bypass capacitor to prevent power disturbance. For devices with a single supply, 0.1 μf is recommended; if there are multiple VCC pins, then 0.01 μf or 0.022 μf is recommended for each power pin. It is acceptable to parallel multiple bypass caps to reject different frequencies of noise. A 0.1 μf and a 1 μf are commonly used in parallel. The bypass capacitor should be installed as close to the power pin as possible for best results. 12 Layout 12.1 Layout Guidelines When using multiple bit logic devices inputs should never float. In many cases, functions or parts of functions of digital logic devices are unused, for example, when only two inputs of a triple-input AND gate are used or only 3 of the 4 buffer gates are used. Such input pins should not be left unconnected because the undefined voltages at the outside connections result in undefined operational states. Figure 6 specifies the rules that must be observed under all circumstances. All unused inputs of digital logic devices must be connected to a high or low bias to prevent them from floating. The logic level that should be applied to any particular unused input depends on the function of the device. Generally they will be tied to GND or VCC whichever make more sense or is more convenient. It is generally acceptable to float outputs, unless the part is a transceiver. If the transceiver has an output enable pin, it will disable the output section of the part when asserted. This will not disable the input section of the I/Os, so they cannot float when disabled. 12.2 Layout Example Vcc Unused Input Input Output Output Unused Input Input Figure 6.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
SN74LVC541APWR
物料型号: - SN54LVC541A - SN74LVC541A

器件简介: 这些是德州仪器生产的八路缓冲器/驱动器,具有3态输出功能。它们设计用于2.7V至3.6V的VCC操作,而SN74LVC541A则设计用于1.65V至3.6V的VCC操作。这些设备具有多种特性,包括支持混合模式信号操作、低功耗、高静电放电(ESD)保护等。

引脚分配: - OE1和OE2:输出使能输入 - A1至A8:输入端 - Y1至Y8:输出端 - VCC:电源引脚 - GND:地线

参数特性: - 工作电压范围:1.65V至3.6V(SN74LVC541A)和2.7V至3.6V(SN54LVC541A) - 输入电压范围:可接受高达5.5V的电压 - 最大传播延迟时间tpd:典型值为5.1纳秒(3.3V供电时) - 输出低电平电压VOL:小于0.8V(3.3V供电时) - 输出高电平电压VOH:大于2V(3.3V供电时)

功能详解: 这些缓冲器/驱动器可以用于驱动总线线或缓冲存储器地址寄存器。它们的3态控制门是一个具有主动低输入的2输入与门,如果任一输出使能(OE1或OE2)输入为高电平,则所有八个输出都将处于高阻态。输入可以由3.3V或5V设备驱动,允许这些设备在混合3.3V/5V系统环境中用作转换器。

应用信息: 这些设备适用于多种总线接口类型的应用,其中数据需要被保持或锁定。它们可以在3.3V下产生24mA的驱动电流,非常适合驱动多个输出和高速应用,最高可达100MHz。输入对5.5V容忍,允许设备降低到VCC。

封装信息: 提供多种封装选项,包括SSOP(20)、TVSOP(20)、VQFN(20)、SOIC(20)和TSSOP(20),具体尺寸和引脚数量如表所示。
