1 / 9 page MOTOROLA CMOS LOGIC DATA 135 MC14034B 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. • Pin–for–Pin Replacement for CD4034B. MAXIMUM RATINGS* (Voltages Referenced to VSS) Symbol Parameter Value Unit VDD DC Supply Voltage – 0.5 to + 18.0 V Vin, Vout Input or Output Voltage (DC or Transient) – 0.5 to VDD + 0.5 V lin, lout Input or Output Current (DC or Transient), per Pin ± 10 mA PD Power Dissipation, per Package† 500 mW Tstg Storage Temperature – 65 to + 150 _C TL Lead Temperature (8–Second Soldering) 260 _C * Maximum Ratings are those values beyond which damage to the device may occur. †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.
