NC7S14 TinyLogic
HS Inverter with Schmitt Trigger Input
NC7S14
TinyLogic HS Inverter with Schmitt Trigger Input
General Description
The NC7 S14 is a sing le high perform ance CMOS Inv erter
with Schm itt Trigger input. The circ uit desig n provide s hys-
teresis between the positive-going and negative going
input thresholds thereby improving noise margins.
Advanced Silicon Gate CMOS fabrication assures high
speed and low power circuit operation over a broad VCC
range. ESD protection diodes inherently guard both input
and output with respect to the VCC and GND rails.
Features
■Space saving SOT23 or SC70 5-lead package
■Ultra small MicroPak leadless packa ge
■Schmitt input hysteresis: > 1V typ
■High speed: tPD 4.5 ns typ
■Low quiescent power: ICC < 1 µA
■Balanced output drive: 2 mA IOL, −2 mA IOH
■Broad VCC operating range: 2V – 6V
■Balanc ed pro pa gat io n delays
■Specified for 3V operation

AC Electrical Characteristics
Note 3: 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 dynam ic operating current by th e ex pression:
ICCD = (CPD) (VCC) (fIN) + (I CCstatic).
