Rochester Electronics Logic - Buffers, Drivers, Receivers, Transceivers SN74F657DW

The SN74F657DW is an octal transceiver designed for bus-oriented applications, featuring a parity generator/checker and 3-state outputs. It includes eight non-inverting buffers with a current sinking capability of 24 mA at the A port and 64 mA at the B port. The device operates with a transmit/receive (T/R) input to control data flow direction, and an output enable (OE) input to place both ports in a high-impedance state when activated. The parity functionality allows for selection between odd and even parity systems, with the PARITY output reflecting the state based on the number of high bits on the A port during transmission. The device is characterized for operation within a temperature range of 0¬8C to 70¬8C and is available in a 24-pin SOIC package. This product is suitable for applications requiring reliable data transmission with parity checking capabilities.
