3 Description

SN54SC245-SEP is an octal bus transceiver with 3-state outputs. All eight channels are controlled by the direction (DIR) pin and output enable (OE) pin. The output enable (OE) controls all outputs in the device. When the OE pin is in the low state, the appropriate outputs as determined by the direction (DIR) pin are enabled. When the OE pin is in the high state, all outputs of the device are disabled. All disabled outputs are placed into the high-impedance state.
