NC7SZ19
TinyLogic UHS 1-of-2 Decoder/Demultiplexer
General Description
Features
The NC7SZ19 is a 1-of-2 decoder with a common output
enable. 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
■ Space saving SC70 6-lead surface mount package
■ Ultra small MicroPak leadless package
■ Ultra High Speed: tPD 2.7 ns Typ into 50 pF at 5V VCC
■ Broad VCC Operating Range; 1.65V to 5.5V
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.
■ Power down high impedance inputs/outputs
■ Overvoltage tolerant inputs facilitate 5V to 3V translation
■ Patented noise/EMI reduction circuitry implemented
