description  
The ’ABT16657 contain two noninverting octal  
transceiver sections with separate parity  
generator/checker circuits and control signals.  
For either section, the transmit/receive (1T/R or  
2T/R) input determines the direction of data flow.  
When 1T/R (or 2T/R) is high, data flows from the  
1A (or 2A) port to the 1B (or 2B) port (transmit  
mode); when 1T/R (or 2T/R) is low, data flows  
from the 1B (or 2B) port to the 1A (or 2A) port  
(receive mode). When the output-enable (1OE or  
2OE) input is high, both the 1A (or 2A) and 1B (or  
2B) ports are in the high-impedance state.

NC – No internal connection  
Odd or even parity is selected by a logic high or low level, respectively, on the 1ODD/EVEN (or 2ODD/EVEN)  
input. 1PARITY (or 2PARITY) carries the parity bit value; it is an output from the parity generator/checker in the  
transmit mode and an input to the parity generator/checker in the receive mode.  
In the transmit mode, after the 1A (or 2A) bus is polled to determine the number of high bits, 1PARITY (or  
2PARITY) is set to the logic level that maintains the parity sense selected by the level at the 1ODD/EVEN (or  
2ODD/EVEN) input. For example, if 1ODD/EVEN is low (even parity selected) and there are five high bits on  
the 1A bus, then 1PARITY is set to the logic high level so that an even number of the nine total bits (eight 1A-bus  
bits plus parity bit) are high.
