1 / 6 page MOTOROLA CMOS LOGIC DATA MC14194B 284 4-Bit Bidirectional Universal Shift Register The MC14194B is a 4–bit static shift register capable of operating in the parallel load, serial shift left, serial shift right, or hold mode. The asynchronous Reset input, when at a low level, overrides all other inputs, resets all stages, and forces all outputs low. When Reset is at a logic 1 level, the two mode control inputs, S0 and S1, control the operating mode as shown in the truth table. Both serial and parallel operation are triggered on the positive–going transition of the Clock input. The Parallel Data, Data Shift, and mode control inputs must be stable for the specified setup and hold times before and after the positive–going Clock transition. • Synchronous Right/Left Serial Operation • Synchronous Parallel Load • Asynchronous Hold (Do Nothing) Mode • Functional Pin for Pin Equivalent of LS194 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 Iin, Iout 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 Q LOGIC DIAGRAM RESET CLOCK DSR S0 S1 1 11 2 9 10 5 6 4 3 DP1 DP0 DP2 DP3 7 DSL Q0 Q1 Q2 Q3 15 14 13 12 D R D Q D Q D Q C C C C R R R VDD = PIN 16 VSS = PIN 8 MOTOROLA SEMICONDUCTOR TECHNICAL DATA © Motorola, Inc. 1995 REV 3 1/94 MC14194B L SUFFIX CERAMIC CASE 620 ORDERING INFORMATION MC14XXXBCP Plastic MC14XXXBCL Ceramic MC14XXXBD SOIC TA = – 55° to 125°C for all packages.
