NC7SZ18
TinyLogic UHS 1-of-2 Non-Inverting Demultiplexer
with 3-STATE Deselected Output
General Description
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
Features
■ Space saving SC70 6-lead surface mount package
■ Ultra small MicroPak leadless package
■ High Impedance output when deselected
pin (S) is LOW or HIGH respectively. The deselected out-
put 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
■ 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
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.
