Certain applications using semiconductor products may involve potential risks of death, personal injury, or severe property or environmental damage “Critical Applications”. When SO is low and S1 is high, data shifts left synchronously and new data is entered at the shift-left serial input.
The data are loaded into the associated flip-flops and appear at the outputs after the positive transition of datahseet clock input. Serial data for this mode is entered at the shift-right datasheeh input. All diodes are 1 N or 1 N Voltage values are with respect to network ground terminal. Ths clock pulse generator Has the following characteristics: This bidirectional shift register is datashee to incorporate.
Inhibit clock do nothing. The register has four distinct modes of operation, namely: Tl warrants performance of its semiconductor products and related software to the specifications 74ls14 at the time of sale in accordance with Tl’s standard warranty. Full text of ” IC Datasheet: Features s Parallel inputs and outputs s Four operating modes: The data is loaded into the associated.

Shift right is accomplished synchronously with the rising. Testing and other quality control techniques are utilized to the extent Tl deems necessary to support this warranty.
SI, clear, and the serial inputs, l cc is tested with a momemtary GND, then 4.
Clocking of the flip-flop is inhibited when both mode control inputs are LOW. Devices also available in Tape and Reel. During loading, serial data flow is inhibited.
With all outputs Dpen, inputs A through D grounded, and 4.

The circuit contains 46 equivalent gates and datashert 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. With all outputs open, inputs A through O grounded, and 4. Inclusion of Tl products in such applications is understood to be fully at datasgeet risk of the customer.
Physical Dimensions inches millimeters unless otherwise noted. Shift right is accomplished synchronously with the rising edge of the clock pulse when SO is high and S 1 is low.
The data is loaded into the associated flip-flops and appear at the outputs after the positive transi- tion of the clock input. Serial data for this mode is entered at the shift-right data. Proper shifting of satasheet is verified at t nt4 with a functional tast.
When testing f maK. In order to minimize risks associated with the customer’s applications, adequate design dztasheet operating safeguards should be provided by the customer to minimize inherent or procedural hazards.
Shift left in the direction Q D toward Q A. J, N, and W packages. During loading, serial data flow is inhibited. Use of Tl products in such applications requires the written approval of an appropriate Tl officer. S V applied to clock.
Clocking of the flip-flop is inhibited when both mode control. A clear pulse is applied prior to each test.
Serial data for this mode datashete entered at the shift-right data fatasheet. 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 datashret by applying the four vatasheet of data and taking both mode control inputs, SO and SIhigh. The register has four distinct modes of operation, namely: 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 dataeheet which such semiconductor products or services might be or are used.
Questions concerning potential risk applications should be directed to Tl through a local SC sales office. Shift right in the direction Q A toward Q D.
