3-State Octal Bus Transceiver IC - 74HC245 The 74HC Series 74HC245 octal bus transceivers are designed for asynchronous two-way communication between data buses. The control function implementation minimizes external timing requirements. The device allows data transmission from the A Bus to the B Bus or from the B Bus to the A Bus depending upon the logic level at the direction control (DIR) input. The enable input (G) can be used to disable the device so that the buses are effectively isolated. Pinout: Pinout Of 74HC245 IC Pin Number Pin Name Description 1 Direction Control (DIR) This pin decides the direction of the Data. 2 to 9 Data Input/output (A0-A7) These 8 pins can be used as 8-bit Input or 8-bit Output pins based on the state of DIR pin 10 Ground (GND) Connected to the ground of the system 11 to 18 Data Input/output (B0-B7) These 8 pins can be used as 8-bit Input or 8-bit Output pins based on the state of DIR pin 19 Output Enable (OE) Active Low pin – Used to Enable/Disable Input 20 Supply Voltage (Vcc) Differential Analog input +. Connect to ADC input
