General Description
The 鈥橝CTQ16245 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 鈥橝CTQ16245 utilizes NSC Quiet Series technology to
guarantee quiet output switching and improved dynamic
threshold performance. FACT Quiet Series
