Texas Instruments SN74165
The ’165 and ’LS165A are 8-bit serial shift registers that shift the data in the direction of QA toward QH when clocked. These registers also feature gated clock (CLK) inputs and complementary outputs from the eighth bit.| Part No. | SN74165 |

SN54165, SN54LS165A, SN74165, SN74LS165A PARALLEL-LOAD 8-BIT SHIFT REGISTERS SDLS062D – OCTOBER 1976 – REVISED FEBRUARY 2002 D Complementary Outputs D Direct Overriding Load (Data) Inputs D Gated Clock Inputs D Parallel-to-Serial Data Conversion TYPE ’165 ’LS165A TYPICAL MAXIMUM CLOCK FREQUENCY 26 MHz 35 MHz TYPICAL POWER DISSIPATION 210 mW 90 mW description Parallel-in access to each stage is made available by eight individual, direct data inputs that are enabled by a low level at the shift/load (SH/LD) input. All inputs are diode-clamped to minimize transmission-line effects, thereby simplifying system design. Clocking is accomplished through a two-input positive-NOR gate, permitting one input to be used as a clock-inhibit function. Holding either of the clock inputs high inhibits clocking, and holding either clock input low with SH/LD high enables the other clock input. Clock inhibit (CLK INH) should be changed to the high level only while CLK is high.
