It is ideal for low power and high speed 3.3V applications; it can be interfaced to 5V signal environment for both inputs and outputs. These 8 bit D-Type latch are controlled by a latch Figure 1: Pin Connection And IEC Logic Symbols enable input (LE) and an output enable input (OE). While the LE inputs is held at a high level, the Q outputs will follow the data input. When the LE is taken low, the Q outputs will be latched at the logic level of D input data. While the (OE) input is low, the 8 outputs will be in a normal logic state (high or low logic level) and while (OE) is in high level, the outputs will be in a high impedance state. It has same speed performance at 3.3V than 5V AC/ACT family, combined with a lower power consumption. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.

器件简介: 74LCX573是一款低压CMOS八位D型锁存器,具有三态输出非反相功能,采用亚微米硅门和双层金属连线C2MOS技术制造。它适用于低功耗和高速3.3V应用,可以与5V信号环境的输入和输出接口兼容。

引脚分配: - 1号引脚:OE(3态输出使能输入,低电平有效) - 2至9号引脚:DO至D7(数据输入) - 11号引脚:LE(锁存使能输入) - 10号引脚:GND(地) - 12至19号引脚:Q0至Q7(3态锁存输出) - 20号引脚:Vcc(正电源电压)

参数特性: - 工作电压范围:2.0V至3.6V(1.5V数据保持) - 对称的输出阻抗:|Ioh|=Iol=24 mA(最小值)在3V电源下 - 高速性能:在3V电源下,最大传播延迟时间为8.0ns - 5V容错输入和输出 - 静电放电(ESD)性能:HBM > 2000V,MM > 200V

功能详解: 当LE输入保持高电平时,Q输出将跟随数据输入。当LE拉低时,Q输出将在D输入数据的逻辑电平被锁存。当OE输入为低电平时,8个输出将处于正常逻辑状态;当OE为高电平时,输出将处于高阻态。

应用信息: 74LCX573适用于需要低功耗和高速性能的应用,如PCI总线接口等。所有输入和输出均配备有防静电放电保护电路,提供2kV的ESD保护和瞬态过电压保护。
