Designed for printer interface applications, the LVCE161284 from Texas Instruments Inc. (TI) is claimed by the company as the industry's first IEEE 1284 interface solution that meets the IEC 61000-4-2 standard for ESD protection.

The LVCE161284 is a feature rich, highly-integrated solution that offers best-in-class ESD protection, and reduces part count and saves board space. It provides 15kV human body model, 8kV contact, and 15kV air-gap discharge protection in accordance with IEC 61000-4-2 (level 4) on the connector interface pins.

The product also offers additional improvements over other 1284 interface devices such as Ioff and Power-Up 3-State to support Hot Insertion, an integrated PMOS transistor to prevent back-drive current, hysteresis at all inputs to provide noise margin, and an Auto-Power-Up feature which prevents printer errors when the printer is turned on and no valid signal is at connector side pins.

The SN74LVCE161284 is available to sample. It is offered in 48-pin SSOP (DL) and TSSOP (DGG) packaging, and is priced at $2 in quantities of 1,000.
