MC14042B
Quad Transparent Latch
The MC14042B Quad Transparent Latch is constructed with MOS
P−channel and N−channel enhancement mode devices in a single
monolithic structure. Each latch has a separate data input, but 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.

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. Temperature Derating: “D/DW” Packages: –7.0 mW/_C From 65_C To 125_C
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 Vout should be constrained
to the range VSS ≤ (Vin or Vout) ≤ 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.
