SN74HC245 Octal Bus Transceiver IC DIP-20 (74HC245 3-State Bidirectional) gm640 meter The connector at End A:The SN74HC245N octal bus transceivers are designed for asynchronous two way communication between data buses. The control function implementation minimizes external timing requirements. The devices allow data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction control (DIR) input. The output enable (OE) input can be used to disable the device so that the buses are effectively isolated.
