With all outputs open, inputs A through O grounded, and 4. Testing and other quality control techniques are utilized to the extent Tl deems necessary to support this warranty. Clocking of the flip-flop is inhibited when both mode control inputs are LOW. Shift right is accomplished synchronously with the rising. Search the history of over billion web pages on the Internet. All diodes are 1 N or 1 N The data are loaded into the associated flip-flops and appear at the outputs after the positive transition of the clock input.

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.

Order Number Package Number. Ths clock pulse generator Has the following characteristics: Shift right in the direction Q A toward Q D. Voltage values are with respect to network ground terminal. During loading, serial data flow is inhibited. Serial data for this mode is entered at the shift-right data.

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. Devices also available in Tape and Reel.

Synchronous parallel load Right shift Left shift Do nothing s Positive edge-triggered clocking s Direct overriding clear Ordering Code: 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.

The register has four distinct modes datasheer operation, namely: The register has four distinct modes of operation, namely: Clocking of the flip-flop is inhibited when both mode control.

Nor does Tl warrant or represent that any license, either express or implied, is granted under 74ls1944 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. Certain applications using semiconductor products may involve potential risks of death, personal injury, or severe property or environmental damage “Critical Applications”.

A clear pulse is applied prior to each test. Inclusion of Tl products in such applications is understood to be fully at datasheet risk of the customer.

Physical Dimensions inches millimeters unless otherwise noted. Clocking of the shift register is inhibited when both mode control inputs are low. Use of Tl products in such applications requires the written approval of an appropriate Tl officer. 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.

Inhibit clock do nothing. During loading, serial data flow is. When testing f maK. When SO is low and Datahseet is high, data shifts left synchronously and new data is entered at the shift-left serial input.

Full text of ” IC Datasheet: Questions concerning potential risk applications should be directed to Tl through a local SC sales office.

Specific testing of all parameters of each device is not necessarily performed, except those mandated by government requirements. With all outputs Dpen, inputs A through D grounded, and 4.

Pin numbers shown are for D, J, N, and W packages. Synchronous parallel loading is accomplished by applying. Shift right is accomplished synchronously with the rising edge of the clock pulse when SO is high and S 1 is low. Shift left in the direction Q D toward Q A.

The data is loaded into the associated flip-flops and appear at the outputs after the positive transi- tion of the clock input.
