5 / 9 page ESD8451, SZESD8451 www.onsemi.com 5 Latch−Up Considerations ON Semiconductor’s 8000 series of ESD protection devices utilize a snap−back, SCR type structure. By using this technology, the potential for a latch−up condition was taken into account by performing load line analyses of common high speed serial interfaces. Example load lines for latch−up free applications and applications with the potential for latch−up are shown below with a generic IV characteristic of a snapback, SCR type structured device overlaid on each. In the latch−up free load line case, the IV characteristic of the snapback protection device intersects the load−line in one unique point (VOP, IOP). This is the only stable operating point of the circuit and the system is therefore latch−up free. In the non−latch up free load line case, the IV characteristic of the snapback protection device intersects the load−line in two points (VOPA, IOPA) and (VOPB, IOPB). Therefore in this case, the potential for latch−up exists if the system settles at (VOPB, IOPB) after a transient. Because of this, ESD8451 should not be used for HDMI applications – ESD8104 or ESD8040 have been designed to be acceptable for HDMI applications without latch−up. Please refer to Application Note AND9116/D for a more in−depth explanation of latch−up considerations using ESD8000 series devices. Figure 11.
