The data is loaded into the associated flip-flops and appear at the outputs after the positive transi- tion of the clock input. Features s Parallel inputs and outputs s Four operating modes: Tl warrants performance of its semiconductor products and related software to 7l4s194 specifications applicable at the time of sale in accordance with Tl’s standard warranty. Ths clock pulse generator Has the following characteristics: When SO is low and S1 is high, data shifts left synchronously and new data is entered at the shift-left serial input.
Devices also available in Tape and Reel. Synchronous parallel loading is accomplished by applying. With all outputs open, inputs A through O grounded, and 4. The data are loaded into the associated flip-flops and appear at the outputs after the positive transition of the clock input.
The data is loaded into the associated. S V applied to clock.

During loading, datasheet data flow is inhibited. Questions concerning potential risk applications should be directed to Tl through a local SC sales office. Voltage values are with respect to network ground terminal. Serial data for this mode is entered at the shift-right data.
Clocking of the shift register is inhibited when both mode control inputs are low. Full text of ” IC Datasheet: Serial data for this mode is entered at the shift-right data input. J, N, and W packages.
Shift right is accomplished synchronously with the rising edge of the clock pulse when SO is high and S 1 is low. Pin numbers shown are for D, J, N, and W packages. Synchronous parallel load Right shift Left shift Do nothing s Positive edge-triggered clocking s Direct overriding clear Ordering Code: Proper shifting of data is verified at t nt4 with a functional tast. Use of Tl products in such applications requires the written approval of an appropriate Tl officer.
Certain applications using semiconductor products may involve potential risks of death, personal injury, or severe property or environmental damage “Critical Applications”. Testing and other quality control techniques are utilized to the extent Tl deems necessary to support this warranty.
Nor does Tl warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right of Tl covering dattasheet relating to any combination, machine, or process in which such semiconductor products or services might be or are used.
This bidirectional shift register is designed to incorporate. In order to minimize risks associated with the customer’s applications, 74ls149 design and operating safeguards should be provided by the customer to minimize inherent or procedural hazards.
Clocking of the flip-flop is inhibited when both mode control inputs are LOW.
The register has four distinct modes of operation, namely: With all outputs Dpen, inputs A through D grounded, and 4. All diodes are 1 N or 1 N Shift left in the direction Q D toward Q A. A clear pulse is applied prior to each test.
SI, clear, and the serial inputs, l cc is tested with a momemtary GND, then 4. Inhibit clock do nothing Shift right in the direction Qa toward Qq Shift left in the direction Qq toward Qa Parallel broadside load Synchronous parallel loading is accomplished by applying the four bits of data and taking both mode control inputs, SO and SIhigh.

During loading, serial data flow is inhibited. Order Number Package Number. Tl assumes no liability for applications assistance, customer product design, software performance, or infringement of patents or services described herein. Shift right is accomplished synchronously with the rising. Clocking of the flip-flop is inhibited when both mode control.
Inclusion of Tl products in such applications is understood to be fully at the risk of the customer. Search the history of over billion web pages on the Internet. The register has four distinct modes of operation, namely: When testing f maK.
Inhibit clock do nothing. Serial data for this mode is entered at the shift-right data input. Specific testing of all parameters of each device is not necessarily performed, except those mandated by government requirements. Shift right in the direction Q A toward Q D. The circuit contains 46 equivalent gates and features parallel inputs, parallel outputs, right-shift and left-shift serial inputs, operating-mode-control inputs, and a direct overriding clear line.
During loading, serial data flow is. Physical Dimensions inches millimeters unless otherwise noted.
