This document provides information about a product called ST1284, which is a single termination network for parallel ports with ±15 kV ESD protection. It is compliant with the IEEE1284 standard and features EMI / RFI noise filtering. The product is highly integrated and comes in a 28-pin QSOP package. It can provide proper termination for 8 data lines, 1 strobe line, 4 control lines, and 4 status lines. The product offers in-system ESD protection of ±15 kV (air discharge) as per IEC 61000-4-2 level 4. It also complies with IEC 61000-4-2 level 4 ±8 kV (contact discharge) and MIL STD 883G - Method 3015-7 Class 3 ±25 kV (human body model) standards. The ST1284-01A8 is suitable for ECP/EPP parallel port termination on desktops, notebooks, workstations, servers, PC peripherals, and set-top boxes.
The STMicroelectronics ST1284-01A8 is a single-device solution designed to provide proper termination for enhanced high-speed parallel ports. It complies with the IEEE 1284 standard and integrates line termination, EMI filtering, and robust Electrostatic Discharge (ESD) protection in a 28-pin QSOP package.
The device is built around two basic cells: one for data and strobe lines, and another for control and status lines. It offers comprehensive ESD protection meeting IEC 61000-4-2 Level 4 requirements (up to +15 kV air discharge) without the need for additional external components.
