DESCRIPTION

The 74LVX238 is a low voltage CMOS 3 TO 8 LINE DECODER fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power, battery operated and low noise 3.3V applications

■ HIGH SPEED:tPD = 5.5ns (TYP.) at VCC = 3.3V

■ 5V TOLERANT INPUTS

■ INPUT VOLTAGE LEVEL:VIL=0.8V, VIH=2V at VCC=3V

■ LOW POWER DISSIPATION:ICC = 2 µA (MAX.) at TA=25°C

■ LOW NOISE:VOLP = 0.3V (TYP.) at VCC = 3.3V

■ SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 4mA (MIN)

■ BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL

■ OPERATING VOLTAGE RANGE: VCC(OPR) = 2V to 3.6V (1.2V Data Retention)

■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 138

■ IMPROVED LATCH-UP IMMUNITY

■ POWER DOWN PROTECTION ON INPUTS

74LVX238MTR属于集成电路（IC） > 信号开关，多路复用器，解码器。意法半导体（ST）集团制造生产的74LVX238MTR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。
