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 The ’165 and ’LS165A are 8-bit serial shift registers that shift the data in the direction of QA toward QH when clocked.
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.
These registers also feature gated clock (CLK) inputs and complementary outputs from the eighth bit.
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.
Parallel loading is inhibited as long as SH/LD is high.
Data at the parallel inputs are loaded directly into the register while SH/LD is low, independently of the levels of CLK, CLK INH, or serial (SER) inputs.
