The MC14174B hex type D flip–flop is constructed with MOS
P–channel and N–channel enhancement mode devices in a single
monolithic structure. Data on the D inputs which meets the setup time
requirements is transferred to the Q outputs on the positive edge of the
clock pulse. All six flip–flops share common clock and reset inputs.
The reset is active low, and independent of the clock.
• Static Operation
• All Inputs and Outputs Buffered
• Diode Protection on All Inputs
• Supply Voltage Range = 3.0 Vdc to 18 Vdc
• Capable of Driving T wo Low–Power TTL Loads or One Low–Power
Schottky TTL Load over the Rated T emperature Range
• Functional Equivalent to TTL 74174

2. Maximum Ratings are those values beyond which damage to the device
may occur.
3. Temperature Derating:
Plastic “P and 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, V
