Testing and other quality control techniques are utilized to the extent Tl deems necessary to support this warranty. Serial data for this mode is entered at the shift-right data.

Pin numbers shown are for D, J, N, and W packages. Physical Dimensions inches millimeters unless otherwise noted. All diodes are 1 N or 1 N Shift left in the direction Q Datasheeet toward Q A.

SI, clear, and the serial inputs, l cc is tested with a momemtary GND, then 4. During loading, serial data flow is.

Order Number Package Number. The data is loaded into the associated. When testing f maK.

Questions concerning potential risk applications should be directed to Tl through a local SC sales office. Clocking of the flip-flop is inhibited when both mode control inputs are LOW. Shift right in the direction Q A toward Q D. Inclusion of Tl products in such applications is understood to be fully at the risk of the customer.


With all outputs open, inputs A through O grounded, and 4. Shift right is accomplished synchronously with the rising edge of the clock pulse when SO is high and S 1 is low.

This bidirectional shift register is designed to incorporate. 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.

Clocking of the flip-flop is inhibited when both mode control.

Voltage values are with respect to network ground terminal. Search the history of over billion web pages on the Internet.

Proper shifting of data is verified at t nt4 with a functional tast. 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. Synchronous parallel load Right shift Left shift Do nothing s Positive edge-triggered clocking s Direct overriding clear Ordering Code: Tl warrants performance of its semiconductor 74ls1194 and related software to the specifications applicable at the time of sale in accordance with Tl’s standard warranty.


Full text of ” IC Datasheet: 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.

Specific testing of all parameters of each device is not necessarily performed, except those mandated by government requirements. Features s Parallel inputs and outputs s Four operating modes: The register has four distinct modes of operation, namely: Use of Tl products 74ls1944 such applications requires the written approval of an appropriate Tl officer.

Synchronous parallel loading is accomplished by applying.

The register has four distinct modes of operation, namely: A clear pulse is applied prior to each test. During loading, serial data flow is inhibited. 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.
