TEL Original Products TE7753/TE7754 DATA SHEET TE7753/TE7754 SUPER I/O EXPANDER www.DataSheet4U.com [Outline] TE7753 and TE7754 are peripheral devices connected to a microprocessor, or general-purpose interface devices each having nine 8-bit parallel data input/output ports. Two port I/O setting modes, soft mode and hard mode, can be selected. Switching the modes eases the connection to an 86-series or 68-series CPU. [Characteristics] 1. 2. 3. 4. 5. Equipped with nine 8-bit parallel I/O ports Allowing I/O setting in bit units (port 8 only) Interface designed for connections with various types of CPUs High drive current (IOL = 12 mA: Port 9 only) Choice of two modes Soft mode : I/O setting is enabled for nine ports by software instructions from the CPU.
