NC7SZ157
TinyLogic
UHS 2-Input Non-Inverting Multiplexer
General Description
The NC7SZ157 is a single, high performance, 2 to 1
CMOS non-inverting multiplexer from Fairchild's Ultra High
Speed Series of TinyLogic
. 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 V
CC
operating range. The device
is specified to operate over the 1.65V to 5.5V V
CC
operat-
ing range. The inputs and outputs are high impedance
when V
CC
is 0V. Inputs tolerate voltages up to 5.5V inde-
pendent of V
CC
operating range.

Absolute Maximum Ratings
(Note 1)
Recommended Operating
Conditions
Note 1: Absolute maximum ratings are DC values beyond which the device
may be damaged or have its useful life impaired. The datasheet specifica-
tions should be met, without exception, to ensure that the system design is
reliable over its power supply, temperature, and output/input loading vari-
ables. Fairchild does not recommend operation outside datasheet specifi-
cations.

AC Electrical Characteristics

PD
is defined as the value of the internal equivalent capacitance which is derived from dynamic operating current consumption (I
CCD
) at no output
loading and operating at 50% duty cycle. (See Figure 2) C
PD
is related to I
CCD
dynamic operatic current by the expression:
I
