NC7ST86
TinyLogic HST 2-Input Exclusive-OR Gate
General Description
The NC7ST86 is a single 2-Input high performance CMOS Exclusive-OR Gate, with TTL-compatible inputs. Advanced Silicon Gate CMOS fabrication assures high speed and low power circuit operation. ESD protection diodes inherently guard both inputs and outputs with respect to the VCC and GND rails. High gain circuitry offers high noise immunity and reduced sensitivity to input edge rate. The TTL-com- patible inputs facilitate TTL to NMOS/CMOS interfacing. Device performance is similar to MM74HCT but with ½ the output current drive of HC/HCT.

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 expression:
ICCD = (CPD) (VCC) (fIN) + (ICC static).
