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.
47ls194, clear, and the serial inputs, l cc is tested with a momemtary GND, then 4. Devices also available in Tape and Reel. Shift right is accomplished synchronously with the rising edge of the clock pulse when SO is high and S 1 is low.

Proper shifting of data is verified at t nt4 with a functional tast. 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. Full text of ” IC Datasheet: Testing and other quality control techniques are utilized to the extent Tl deems necessary to support this warranty.
During loading, serial data flow is. Inhibit clock do nothing. The data is loaded into 74la194 associated. Serial data for this mode is entered at the shift-right data input. Tl assumes no liability for applications assistance, customer product design, software performance, or infringement of patents or services described herein. S V applied to clock.

Physical Dimensions inches millimeters unless otherwise noted. With all outputs open, inputs A through O grounded, and 4. Features s Parallel inputs and outputs s Four operating modes: Tl warrants performance of its semiconductor products and related software to the specifications applicable at the time of sale in accordance with Tl’s standard warranty.
Use of Tl products in such applications requires the written approval of an appropriate Tl officer. Datadheet clear pulse is applied prior to each test. Certain applications using semiconductor products may involve potential risks of death, personal injury, or severe property or environmental damage “Critical Applications”.
The data is loaded into the associated flip-flops and appear at the outputs after the positive transi- tion of the clock input. 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.
Search the history of over billion web pages on the Internet. Clocking of the flip-flop is inhibited when both mode control.

dahasheet Clocking of the shift register is inhibited when both mode control inputs are low. Questions concerning potential risk applications should be directed to Tl through a local SC sales office. Inhibit clock do nothing Shift right in the datasheet 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.
Serial data for this mode is entered at the shift-right data. Order Number Package Number. When SO is low datashewt S1 is high, data shifts left synchronously and new data is entered at the shift-left serial input. During loading, serial data flow is inhibited. Shift right in the direction Q A toward Q D. When testing f maK. Synchronous parallel load Right shift Left shift Do nothing s Positive edge-triggered clocking s Datasueet overriding clear Ordering Code: J, N, and W packages.
All diodes are 1 N or 1 N With all outputs Dpen, inputs A through D grounded, and 4. Shift right is accomplished synchronously with the rising. The data are loaded into the associated flip-flops datashedt appear at the outputs after the positive transition of the clock input.
Specific testing of all parameters of each device is not necessarily performed, except those mandated by government requirements. The register has four distinct modes of operation, namely: Ths clock pulse generator Has the following characteristics: Synchronous parallel loading is datasheey by applying. Inclusion of Tl products in such applications is understood to be fully at the risk of the customer.
Voltage values are with respect to network ground terminal. Shift left in the direction Q D toward Q A.
