[ /Title (CD74 HC194, CD74H CT194) /Subject (HighSpeed CMOS Logic 4-Bit CD54HC194, CD74HC194, CD74HCT194 Data sheet acquired from Harris Semiconductor SCHS164G September 1997 - Revised May 2006 High-Speed CMOS Logic 4-Bit Bidirectional Universal Shift Register Features Description • Four Operating Modes - Shift Right, Shift Left, Hold and Reset • Synchronous Parallel or Serial Operation • Fanout (Over Temperature Range) - Standard Outputs . . . . . . . . . . . . . . . 10 LSTTL Loads - Bus Driver Outputs . . . . . . . . . . . . . 15 LSTTL Loads The ’HC194 and CD74HCT194 are 4-bit shift registers with Asynchronous Master Reset (MR). In the parallel mode (S0 and S1 are high), data is loaded into the associated flip-flop and appears at the output after the positive transition of the clock input (CP). During parallel loading serial data flow is inhibited. Shift left and shift right are accomplished synchronously on the positive clock edge with serial data entered at the shift left (DSL) serial input for the shift left mode, and at the shift right (DSR) serial input for the shift right mode. Clearing the register is accomplished by a Low applied to the Master Reset (MR) pin. • Wide Operating Temperature Range . . . -55oC to 125oC Ordering Information • Typical fMAX = 60MHz at VCC = 5V, CL = 15pF, TA = 25oC • Asynchronous Master Reset • Balanced Propagation Delay and Transition Times • Significant Power Reduction Compared to LSTTL Logic ICs PART NUMBER • HC Types - 2V to 6V Operation - High Noise Immunity: NIL = 30%, NIH = 30% of VCC at VCC = 5V • HCT Types - 4.5V to 5.5V Operation - Direct LSTTL Input Logic Compatibility, VIL= 0.8V (Max), VIH = 2V (Min) - CMOS Input Compatibility, Il ≤ 1µA at VOL, VOH Pinout CD54HC194 (CERDIP) CD74HC194 (PDIP, SOIC, SOP, TSSOP) CD74HCT194 (PDIP) TOP VIEW MR 1 TEMP.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability information and additional product content details. TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
