74LCX138TTR集成电路（IC）的信号开关多路复用器解码器规格书PDF中文资料

74LCX138TTR属于集成电路（IC）的信号开关多路复用器解码器。由意法半导体集团制造生产的74LCX138TTR信号开关，多路复用器，解码器逻辑型信号开关、多路复用器和编码器 IC 可用于对以数字格式表示数据的电信号进行路由和选择。这些器件与设计用于模拟信号的类似产品有所不同，它们保留的信息表示为两个电状态之一，而不是两个外部界限内的无穷变化量。

描述 Description

The 74LCX138 is a low voltage CMOS 3 to 8 line decoder (inverting) fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power and high speed 3.3V applications; it can be interfaced to 5V signal environment for inputs.

特性 Features

■ 5V tolerant inputs

■ High speed:

– tPD = 6.7ns (Max) at VCC = 3V

■ Power down protection on inputs and outputs

■ Symmetrical output impedance:

– |IOH| = IOL = 24mA (Min) at VCC = 3V

■ PCI bus levels guaranteed at 24mA

■ Balanced propagation delays:

– tPLH ≅ tPHL

■ Operating voltage range:

– VCC (Opr) = 2.0V to 3.6V

■ Pin and function compatible with 74 series 138

■ Latch-up performance exceeds 500mA (JESD 17)

■ ESD performance:

– HBM > 2000V

(MIL STD 883 method 3015); MM > 200V
