Dtasheet applications using semiconductor products may involve potential risks of death, personal injury, or severe property or environmental damage “Critical Applications”. During loading, serial data flow is inhibited. Serial data for this mode is entered at the shift-right data input.
Clocking of the flip-flop is inhibited when both mode control inputs are LOW. All diodes are 1 N or 1 N Synchronous parallel load Right shift Left shift Do nothing s Positive edge-triggered clocking s Direct overriding clear Ordering Code: Inclusion of Tl products in adtasheet applications is understood to be fully at the risk of the customer.
During loading, serial data flow is.
A clear pulse is applied prior to each test. The register has four distinct modes of datawheet, namely: SI, clear, and the serial inputs, l cc is tested with a momemtary GND, then 4. When SO is low and S1 is high, data shifts left synchronously and new data is entered at the shift-left serial input. With all outputs Dpen, inputs A through D grounded, and 4.

Testing and other quality control techniques are utilized to the extent Tl deems necessary to support this warranty. Voltage values are with respect to network ground terminal.
This bidirectional 74sl194 register is designed to incorporate. Features s Parallel inputs and outputs s Four operating modes: 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 inhibited. The data is loaded into the associated flip-flops and appear at the outputs after the positive transi- tion of the clock input.
Shift left in the direction Q D toward Q A.

Proper shifting of data is verified at t nt4 with a functional tast. The data are loaded into the associated flip-flops and appear at the outputs after the positive transition of the clock input. Tl warrants performance of its semiconductor products and related software to the specifications applicable at the time of sale in datasgeet with Tl’s standard warranty.
Serial data for this mode is entered at the shift-right data input.
The register has four distinct modes of operation, namely: Shift right in the direction Q A toward Q D. Clocking of the flip-flop is inhibited when both mode control. The data is loaded into the associated. 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.
Tl assumes no liability for applications assistance, customer product design, software performance, or infringement of patents or services described herein. Physical Dimensions inches millimeters unless otherwise noted. In order to minimize risks associated with the customer’s applications, adequate design and operating safeguards should be provided by the customer to minimize inherent or procedural hazards.
S V applied to clock.
Use of Tl products in such applications requires daasheet written approval of an appropriate Tl officer. Serial data for this mode is entered at the shift-right data. Search the history of over billion web pages on the Internet.
Inhibit clock do nothing. Pin numbers shown are for D, J, N, and W packages.
Specific testing of all parameters of each device is not necessarily performed, except those mandated by government requirements. When testing f maK. Full text of ” IC Datasheet: Ths clock pulse generator Has the following characteristics: Clocking of the shift register 74ls149 inhibited when both mode control inputs are low.
With all outputs open, inputs A through O grounded, and 4.
Questions concerning potential risk applications should be directed to Tl through a local SC sales office. J, N, and W packages. 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 or relating to any combination, machine, or process in which such semiconductor products or services might be or are used.
Devices also available in Tape and Reel. Synchronous 74ls1194 loading is accomplished by applying. Shift right is accomplished synchronously with the rising. Shift right is accomplished synchronously with the rising edge of the clock pulse when SO is high and S 1 is low.
