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 datwsheet line.
Testing and other quality control techniques are utilized to the extent Tl deems necessary to support this warranty. Use of Tl products in such applications requires dattasheet written approval of an appropriate Tl officer.

Synchronous parallel load Right shift Left shift Do nothing s Positive edge-triggered clocking s Direct overriding clear Ordering Code: All diodes are 1 N or 1 74ls19 During loading, serial data flow is. Clocking of the flip-flop is inhibited when both mode control. Shift right in the direction Q A toward Q D. Physical Dimensions inches millimeters unless otherwise noted.
When testing f maK. Inclusion of Tl products in such applications is understood to be fully at the risk of the customer. Tl assumes no liability for applications assistance, customer product design, software performance, or infringement of patents or services described herein. A clear pulse is applied prior to each test.

J, N, and W packages. Clocking of the shift register is inhibited when both mode control inputs are low. Shift left in the direction Q D toward Q A.
This bidirectional shift register is designed to incorporate. Specific testing of all parameters of each device is not necessarily performed, except those mandated by government requirements.
Certain applications using semiconductor products may involve potential risks of death, personal injury, or severe property or environmental damage “Critical Applications”. Pin numbers shown are for D, J, N, and W packages.
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. Shift right is accomplished synchronously with the rising edge of the clock pulse when SO is high and S 1 is low. The register has four distinct modes of operation, namely: Search the history of over billion web pages on the Internet.
Serial data for this mode is entered at the shift-right data input. Questions concerning potential risk applications should be datasheef to Tl through a local SC sales office. Voltage values are with respect to network ground terminal. During loading, serial data flow is inhibited. Full text of ” IC Datasheet: Proper shifting of data is verified at t nt4 with a functional tast.

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. Serial data for this mode is entered at the shift-right data input.
SI, clear, and the serial inputs, l cc is tested with a momemtary GND, then 4. 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. The data is loaded into the associated flip-flops and appear at the outputs after the positive transi- tion of the clock input.
Shift right is accomplished synchronously with the rising. Serial data for this mode is entered at the shift-right data.
Ths clock pulse generator Has the satasheet characteristics: Devices also available in Tape and Reel. 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.
Clocking of the flip-flop is inhibited when both mode control inputs are LOW. Features s Parallel inputs and outputs s Four operating modes: The 74ls1944 are loaded into the associated flip-flops and appear at the outputs after the positive transition of the clock input.
Order Number Package Number. Inhibit clock do nothing. With all outputs open, inputs A through O grounded, and 4. When SO is low and S1 is high, data shifts left synchronously and new data is entered at the shift-left serial input. Synchronous parallel loading is accomplished by applying. With 74sl194 outputs Dpen, inputs A through D grounded, and 4.
