Designed for use as an interface between a 5V bus and a 3.3V bus in a mixed 5V/3.3V supply systems, it achieves high speed operation while maintaining the CMOS low power dissipation. This IC is intended for two-way asynchronous communication between data buses and the direction of data transmission is determined by DIR input. The enable input G can be used to disable the device so that the buses are effectively isolated. The A-port interfaces with the 3V bus, the B-port with the 5V bus. All inputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage. 74LVX3245 OCTAL DUAL SUPPLY BUS TRANSCEIVER PIN CONNECTION AND IEC LOGIC SYMBOLS ORDER CODES PACKAGE TUBE T & R SOP 74LVX3245M 74LVX3245MTR TSSOP 74LVX3245TTR TSSOP SOP |
