General Description
The 鈥橝CTQ16244 contains sixteen non-inverting buffers with
TRI-STATE outputs designed to be employed as a memory
and address driver, clock driver, or bus oriented transmitter/
receiver. The device is nibble controlled. Each nibble has
separate TRI-STATE control inputs which can be shorted to-
gether for full 16-bit operation.
The 鈥橝CTQ16244 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.
