TinyLogic UHS Dual Buffer
with 3-STATE Outputs
NC7WZ125
Description
The NC7WZ125 is a Dual Non−Inverting Buffer with independent
active LOW enables for the 3−STATE outputs. The Ultra High Speed
device is fabricated with advanced CMOS technology to achieve
superior switching performance 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 1.65 V to 5.5 V V
CC
operating range. The inputs and outputs are high impedance when
V
CC
is 0 V. Inputs tolerate voltages up to 5.5 V independent of V
CC
operating range. Outputs tolerate voltages above V
CC
when in the
3−STATE condition.

Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality
should not be assumed, damage may occur and reliability may be affected.
1. The input and output negative voltage ratings may be exceeded if the input and output diode current ratings are observed.

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 5) C
PD
is related to I
CCD
dynamic operating current by the expression:
I

) (V

) (f
