NC7SZ19
TinyLogic UHS 1-of-2 Decoder/Demultiplexer
General Description
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 lo w static power d issipation over a
broad VCC operating range. The device is specified to
operate o ver the 1.65V to 5.5V VCC operating range. T he
inputs and outputs are high impedance when VCC is 0V.
Inputs tolerate voltages up to 5.5V independent of VCC
operati ng ran ge .
Features
■Space saving SC70 6-lead surface mount package
■Ultra small MicroPak leadless packa ge
■Ultra High Speed: tPD 2.7 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

AC Electrical Characteristics
Note 2: CPD is defined as the value of the internal equivalent capacitance which is derived from dynamic operating current consumption (ICCD) at no output
loading and operating at 50% duty cycle. (See Figure 2.) CPD is related to ICCD dynamic op erating cu rrent by th e ex pressio n:
ICCD = (CPD)(VCC)(fIN) + (ICCstatic).
