Description & Applications This 2-to-4 line decoder is designed for 1.65-V to 5.5-V VCC operation.The SN74LVC1G139 2-line to 4-line decoder is designed to be used in high-performance memory-decoding or data-routing applications requiring very short propagation delay times. In high-performance memory systems, this decoder can be used to minimize the effects of system decoding. When used with high-speed memories utilizing a fast enable circuit, the delay times of these decoders and the enable time of the memory usually are less than the typical access time of the memory. This means that the effective system delay introduced by the decoder is negligible. Available in the Texas Instruments NanoStar? and NanoFree? Packages Supports 5-V VCC Operation Inputs Accept Voltages to 5.5 V Max tpd of 4.9 ns at 3.3 V Low Power Consumption, 10-μA Max ICC ±24-mA Output Drive at 3.3 V Ioff Supports Partial-Power-Down Mode Operation Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II
描述与应用 这个2到4线的解码器是专为1.65-V到5.5 V的VCC操作。SN74LVC1G1392线至4线译码器被设计要用于高性能存储器,解码或数据路由需很短的传输延迟时间的应用程序。在高性能存储器系统中,该解码器可用于系统解码的影响减到最小。一起使用时,利用一个快速的使能电路的高速存储器,这些解码器的延迟时间和存储器的使能时间通常小于存储器典型的存取时间的。这意味着,由解码器的有效系统引入的延迟是可以忽略不计的。 可用德州仪器NANOSTAR?和NanoFree?套件 支持5-V VCC操作 接受输入电压到5.5 V 在3.3 V最大TPD为4.9 ns 低功耗,10μA最大ICC ±24 mA输出驱动,在3.3 V时 IOFF支持部分断电模式操作 闭锁性能超过100 mA每JESD 78,II类
