1 / 6 page 54ACTQ16245 16-Bit Transceiver with TRI-STATE® Outputs General Description The ’ACTQ16245 contains sixteen non-inverting bidirec- tional buffers with TRI-STATE outputs and is intended for bus oriented applications. The device is byte controlled. Each has separate control inputs which can be shorted to- gether for full 16-bit operation. The T/R inputs determine the direction of data flow through the device. The OE inputs dis- able both the A and B ports by placing them in a high imped- ance state. The ’ACTQ16245 utilizes NSC Quiet Series technology to guarantee quiet output switching and improved dynamic threshold performance. FACT Quiet Series® features GTO® output control for superior performance.
