Revised May 2003 NC7SZ18 TinyLogic UHS 1-of-2 Non-Inverting Demultiplexer with 3-STATE Deselected Output General Description Features The NC7SZ18 is a 1-of-2 non-inverting demultiplexer. The device will buffer the data on the A pin and pass to either output Y0 or Y1 dependent on whether state of the select pin (S) is LOW or HIGH respectively. The deselected output will be placed into a high impedance state. The device is fabricated with advanced CMOS technology to achieve ultra high speed with high output drive while maintaining low static power dissipation over a broad VCC operating range. The device is specified to operate over the 1.65V to 5.5V VCC operating range. The inputs and outputs are high impedance when VCC is 0V. Inputs tolerate voltages up to 5.5V independent of VCC operating range. ■ Space saving SC70 6-lead surface mount package ■ Ultra small MicroPak leadless package ■ High Impedance output when deselected ■ Ultra High Speed: tPD 2.5 ns Typ into 50 pF at 5V VCC ■ Broad VCC Operating Range; 1.65V to 5.5V ■ Power down high impedance inputs/outputs ■ Overvoltage tolerant inputs facilitate 5V to 3V translation ■ Patented noise/EMI reduction circuitry implemented Ordering Code: Order Package Product Code Number Number Top Mark NC7SZ18P6X MAA06A Z18 6-Lead SC70, EIAJ SC88, 1.25mm Wide 3k Units on Tape and Reel NC7SZ18L6X MAC06A D5 6-Lead MicroPak, 1.0mm Wide 5k Units on Tape and Reel Package Description Supplied As Connection Diagrams Pin Descriptions Pin Names Description A Data Input S Demultiplexer Select Y0, Y1 Outputs Pin Assignments for SC70 Function Table Input S Output A Y0 Y1 L L L Z L H H Z Pin One Orientation Diagram H L Z L AAA = Product Code Top Mark - see ordering code H H Z H Note: Orientation of Top Mark determines Pin One location.
