MOTOROLA CMOS LOGIC DATAMC14042B
156
The MC14042B Quad Transparent L atch is constructed w ith MOS
P–channel a nd N –channel e nhancement m ode devices i n a single
monolithic s tructure. Each l atch has a separate d ata input, b ut all four
latches share a common clock. The clock polarity (high or low) used to
strobe data through the latches can be reversed using the polarity input.
Information present at the data input is transferred to outputs Q and Q
during
the clock level which is determined by the polarity input. When the polarity
input is in the logic “0” state, data is transferred during the low clock level,
and when the polarity input is in the logic “1” state the transfer occurs during
the high clock level.

#Data labelled “Typ” is not to be used for design purposes but is intended as an indication of the IC’s potential performance.
**The formulas given are for the typical characteristics only at 25_C.
†To calculate total supply current at loads other than 50 pF:
IT(CL) = IT(50 pF) + (CL – 50) Vfk
where: IT is in µA (per package), CL in pF, V = (VDD – VSS) in volts, f in kHz is input frequency, and k = 0.004.
This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However,
precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance
circuit. For proper operation, Vin and V
out
should be constrained to the range VSS ≤ (Vin or V
out
) ≤ VDD.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS or VDD). Unused outputs must
be left open.
