DESCRIPTION

The ST1284-xxA8/T8 is a highly integrated termination for enhanced high speed parallel ports. The integrated termination complies to the IEEE1284 Standard recommendations and government EMC compatibility requirements. It is built around two basic cells. The first one (Cell 1) provides line termination, EMI filtering and ESD protection for the Strobe and Datalines while the second one (Cell 2) provides EMI filtering and ESD protection for the Control and Status lines. In addition, ST1284-xxA8 provides extra protection against ESD.

FEATURES

■ One device for parallel port termination

■ Compliant with IEEE1284 standard

■ EMI / RFI noise filtering

■ Highly integrated solution in 28 pin QSOP and TSSOP packages

■ One single device provides the proper termination for 8 datalines, 1 strobe line, 4 control lines and 4 statuts lines

■ In system ESD protection of ±15 kV (air discharge) as per IEC61000-4-2 level 4

MAIN APPLICATIONS

ECP/EPP Parallel Port termination on:

■ Desktops

■ Notebooks

■ Workstations

■ Servers

■ PC Peripherals

■ Set Top Box

ST1284-03A8RL属于滤波器 > EMI/RFI 滤波器（LC，RC 网络）。意法半导体（ST）集团制造生产的ST1284-03A8RLEMI/RFI 滤波器（LC，RC 网络）该系列产品将几种无源元器件集成到单个装置中，可用于产生电流的频率依赖性阻抗。尽管有其他类型，但大多数都是用于抑制不必要高频信号传输的低通型，否则可能会导致干扰或意外操作。
