SEMICONDUCTOR TECHNICAL DATA
8-Bit Universal Bus Register
The MC14034B is a bidirectional 8–bit static parallel/serial, input/output
bus register. The device contains two sets of input/output lines which allows
the bidirectional transfer of data between two buses; the conversion of serial
data to parallel form, or the conversion of parallel data to serial form.
Additionally the serial data input allows data to be entered shift/right, while
shift/left can be accomplished by hard–wiring each parallel output to the
previous parallel bit input.
Other useful applications for this device include pseudo–random code
generation, sample and hold register, frequency and phase–comparator,
address or buffer register, and serial/parallel input/output conversions.
• Bidirectional Parallel Data Input
• Diode Protection on All Inputs
• Supply Voltage Range = 3.0 Vdc to 18 Vdc
• Capable of Driving Two Low–power TTL Loads or One Low–power
Schottky TTL Load Over the Rated Temperature Range.

†Temperature Derating:
Plastic “P and D/DW” Packages: – 7.0 mW/_C From 65_C To 125_C
Ceramic “L” Packages: – 12 mW/_C From 100_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.
