***AS USD: The SN74F657 contains eight noninverting buffers with 3-state outputs and an 8-bit parity generator/checker. It is intended for bus-oriented applications. The buffers have a specified current sinking capability of 24 mA at the A port and 64 mA at the B port.

***AS INSRUMENTS: The transmit/receive (T/R\) input determines the direction of the data flow through the bidirectional transceivers. When T/R\ is high, data is transmitted from the A port to the B port. When T/R\ is low, data is received at the A port from the B port.

***as Instr.: When the output enable () input is high, both the A and B ports are placed in a high-impedance state (disabled). The ODD/EVEN\ input allows the user to select between odd or even parity systems. When transmitting from A port to B port (T/R\ high), PARITY is an output from the generator/checker. When receiving from B port to A port (T/R\ low), PARITY is an input.

***AS INSTRU: When transmitting (T/R\ high), the parity select (ODD/EVEN\) input is made high or low as appropriate. The A port is then polled to determine the number of high bits.The PARITY output goes to the logic state determined by ODD/EVEN\ and the number of high bits on A port. When ODD/EVEN\ is low (for even parity) and the number of high bits on A port is odd, the PARITY will be high, transmitting even parity. If the number of high bits on A port is even, the PARITY will be low, keeping even parity.

***ASI: When in the receive mode (T/R\ low), the B port is polled to determine the number of high bits. If ODD/EVEN\ is low (for even parity) and the number of highs on B port is:

***: The SN74F657 is characterized for operation from 0°C to 70°C.
