54LS194A General Description
This bidirectional shift register is designed to incorporate virtually all of the features a system designer may want in a
shift register they feature parallel inputs parallel outputs right-shift and left-shift serial inputs operating-mode-control
nputs and a direct overriding clear line The register has our distinct modes of operation namely: Parallel (broadside) load right (in the direction QA toward QD) Shift left (in the direction QD toward QA) Inhibit clock (do nothing)Synchronous parallel loading is accomplished by applying he four bits of data and taking both mode control inputs S0
and S1 high The data is loaded into the associated flip- lops and appear at the outputs after the positive transition
of the clock input During loading serial data flow is inhibited
Shift right is accomplished synchronously with the rising edge of the clock pulse when S0 is high and S1 is lowSerial data for this mode is entered at the shift-right data input When S0 is low and S1 is high data shifts left synchronously and new data is entered at the shift-left serial input
Clocking of the flip-flop is inhibited when both mode control inputs are low

54LS168
The 54LS168 is a fully synchronous 4-state updown coun- ter featuring a preset capability for programmable operation carry lookahead for easy cascading and a UD input to con- trol the direction of counting It counts in the BCD (8421) sequence and all state c...
54LS164
These 8-bit shift registers 54LS164 feature gated serial inputs and an asynchronous clear. A low logic level at either input inhibits entry of the new data, and resets the first flip-flop to the low level at the next clock pulse, thus providing complete con...
54LS163A
These synchronous, presettable counters 54LS163A feature an internal carry look-ahead for application in high-speed counting designs. The LS161A and LS163A are 4-bit binary counters. The carry output is decoded by means of a NOR gate, thus preventing spikes ...
