NC7S32
TinyLogic HS 2-Input OR Gate
General Description
The NC7S32 is a single 2-Input high performance CMOS OR Gate. Advanced Silicon Gate CMOS fabrication assures high speed and low power circuit operation over a broad VCC range. ESD protection diodes inherently guard both inputs and output with respect to the VCC and GND rails. Three stages of gain between inputs and outputs assures high noise immunity and reduced sensitivity to input edge rate.
Features
■Space saving SOT23 or SC70 5-lead package
■High Speed; tPD 3.5 ns typ
■Low Quiescent Power; ICC < 1 µ A
■Balanced Output Drive; 2 mA IOL, − 2 mA IOH
■Broad VCC Operating Range: 2V–6V
■Balanced Propagation Delays
■Specified for 3V Operation

Note 1: Absolute maximum ratings are those values beyond which damage to the device may occur. The databook specifications should be met, without exception, to ensure that the system design is reliable over its power supply, temperature, and output/input loading variables. Fairchild does not recommend operation of circuits outside the databook specifications.
Note 2: Unused inputs must be held HIGH or LOW. They may not float.

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 dynamic operating current by the expression:
ICCD = (CPD) (VCC) (fIN) + (ICCstatic).
