NC7WZ241
TinyLogic UHS Dual Buffer
with 3-STATE Outputs
Description
The NC7WZ241 is a Dual Non−Inverting Buffer with 3−STATE
outputs. The output enable circuitry is organized as active LOW for
one buffer and active HIGH for the other buffer, thus facilitating
transceiver operation.
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 VCC operating range. The device is specified to operate over the
1.65 V to 5.5 V VCC operating range. The inputs and outputs are high
impedance when VCC is 0 V. Inputs tolerate voltages up to 5.5 V
independent of VCC operating range. Outputs tolerate voltages above
VCC when in the 3−STATE condition.

5. 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 6) CPD is related to ICCD dynamic operating current by the expression:
ICCD = (CPD) (VCC) (fIN) + (ICCstatic).
