TinyLogic UHS Buffer with
Three-State Output
Description
The NC7SZ125 is a single buffer with three−state output from
ON Semiconductor’s Ultra−High Speed (UHS) 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 very broad VCC operating range. The device is
specified to operate over the 1.65 V to 5.5 V range. The inputs and
output are high impedance above ground when VCC is 0 V. Inputs
tolerate voltages up to 5.5 V independent of VCC operating voltage.
The output tolerates voltages above VCC when in the 3−STATE
condition.
Features
•Ultra−High Speed: tPD 2.6 ns (Typical) into 50 pF at 5 V VCC
•High Output Drive: ±24 mA at 3 V VCC
•Broad VCC Operating Range: 1.65 V to 5.5 V
•Matches Performance of LCX when Operated at 3.3 V VCC
•Power Down High−Impedance Inputs / Outputs
•Over−Voltage Tolerance Inputs Facilitate 5 V to 3 V Translation
•Proprietary Noise / EMI Reduction Circuitry
•Ultra−Small MicroPak Packages
•Space−Saving SC−74A and SC−88A Packages
•These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS
Compliant

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